Drop -fno-... compiler flags from CMakeLists (#4457)
- `-fno-builtin` should not be necessary: a) by default, we assume
  that a libc exists on the system the project is compiled for, but
  b) even if the assumption does not hold, `-fno-builtin` can be
  passed as an external CFLAG to the build system, plus c) the use
  of builtins is expected to help both code size and performance.
  (Except when jerry-math is enabled.)
- `-fno-stack-protector` should not be necessary: it is the default
  not to instrument code with stack protection.

Officially introduce amalgamated builds (#4416)
Remove redundancy between all-in-one and all-in-one-source builds
by keeping only the second, and adopt the more established term
"amalgamated" build for it. This change includes the following:

- Replace `ENABLE_ALL_IN_ONE` and `ENABLE_ALL_IN_ONE_SOURCE` cmake
  options with `ENABLE_AMALGAM` top-level option.
- Replace `--all-in-one` option of `build.py` helper with
  `--amalgam`.
- Merge the `srcmerger.py` and `srcgenerator.py` tool scripts into
  `amalgam.py` (with improvements).
- Update documentation.

Disable libjerry-math by default (#4428)
Normally, it is more usual and safe to use a toolchain's native
math library. Especially, if multiple components of a project use
math functions, in which case all components should be linked
against the same libm.

The libjerry-math can be used, of course, but as it needs extra
care and consideration, it should be opt-in.

Rename jerry-libm to jerry-math (#4410)
That "libm" in the name of the library resulted in awkward naming
on *nix systems (`libjerry-libm.*`, "lib" occurring twice). And the
name of the corresponding header is `math.h` anyway.

Note that this is a breaking change in some sense. The commit
contains no API change, but the build system does change for users
of the math library.

8ee8bc2767 Improve libfuzz integration (#2916)
- Allow command line tools to build together with libfuzzer driver.
  Compile everything with `-fsanitize=fuzzer-no-link` to prevent
  linking in libfuzzers's `main` symbol in all executables (causing
  duplicate symbol errors in command line tools), and add
  `-fsanitize=fuzzer` to the libfuzzer driver only.

- Make ASan optional when building with libfuzzer to allow the user
  to choose freely from available sanitizers (e.g., UBSan, MSan,
  HWASan).

- Stabilize libfuzzer by resetting PRNG seed at every invocation.

Remove jerry-libc (#2332)
Rationale:
- There is no port under targets/ that would use it. All of them
  turn it off when building.
- That's no surprise, as jerry-libc supports no barebone MCUs but
  posix targets with syscalls only. Actually, that's Linux only,
  because macOS builds have turned off the use of jerry-libc a
  while ago.
- And there is no point in maintaining a highly restricted set of
  libc functions: as soon as someone wants to use JerryScript in a
  scenario that needs more functions than jerry-main, they have to
  choose a different libc (most problably the compiler's default
  one).

I think that we should not keep supporting an otherwise unused
library for the purposes of jerry-main on arm/x86/x64-linux  only.

b61d0ed856 Rework command line handling of build tool (#2373)
In `tools/build.py`:
- For the sake of readability, group CLI arguments as general build
  options, options to control the building of components, and
  component-specific options.
- To prevent duplications, remove the defaults from those CLI
  arguments that correspond to CMake options and have defaults in
  any of the CMakeLists. Should any of the defaults change, they
  will have to be changed at a single place only. (Those options
  that are not set on the command line of `tools/build.py` are not
  passed as options to `cmake` either.)
- Convert `--unittests` and `--doctests` to ON/OFF options like the
  rest of the component switches.
- Touch on some of the help messages of the CLI arguments.

Other changes:
- The change in `--unittests` and `--doctests` is a slightly CLI-
  breaking change of `tools/build.py`. Thus, follow up on this in
  `tools/run-tests.py`.
- Move `ENABLE_ALL_IN_ONE` into `jerry-core` as it is not a general
  option but specific to that component.
- Remove the forcing of `ENABLE_ALL_IN_ONE` for some compilers/
  platforms as it is still an option, not a hard requirement.

Related changes:
- Collect unit test binaries in the `tests` subdir of the build
  tree instead of `bin`.
- The `ls`-based collection of the unit test binaries had some
  shortcomings hitherto unrevealed (it didn't filter for files so
  it could potentially "collect" dictionaries, too), which has now
  been replaced with a more stable `find`-based solution.

a0db3ee5b3 Ensure that the test version of the command line tool is stable for benchmarking (#2076)
Some benchmark suites contain test cases that have nonreproducible
behaviour. This is mostly caused by relying on "now" when dealing
with dates or timestamps, instead of using a fixed moment. (A
notorious example is the crypto-aes.js test case of the sunspider
bechmark suite, where the heap memory consumption can vary between
34K-41K heap because of using `(new Date()).getTime()`.)

This commit renames the jerry-minimal command line tool to
jerry-test (to better reflect its purpose) and adds extra code,
which intercepts some calls to libc (`gettimeofday`, `rand`) and
pins their results to some fixed values. This makes the tool
useless in a general case but ensures stable results when
benchmarking -- for which it is mostly used.

As a side effect, the commit also changes jerry-libc by making all
libc functions weak symbols to allow their override from
application code.

81952f3cd0 module: Re-implement using library constructors/destructors (#2018)
By using constructors/destructors we unify the case of static linking with
that of dynamic linking, and we reuse the build flag FEATURE_INIT_FINI. Using
constructors/destructors also allows us to cover the case where library
constructor/destructor functionality is unavailable, because we can expose the
module registration/unregistration functions as global symbols, to be called
explicitly from within the application.

8aca0acaa1 Aftermath of PRs #1505 and #1755 (#1771)
PR #1505 added support for TI compiler. It explicitly added a
message to notify the user that static linking is forced. PR #1755
added a more generic approach to signal such forced settings and
adapted the TI-specific static linking notification to this
approach. However, it turned out that TI forcibly changed another
setting, too: it disabled release binary stripping, but without
notification. This patch fixes this by moving the setting override
to a consistent place and adding a notification.

PR #1505 also added some source code changes, most importantly a
complex struct initialization for a variable in
`ecma-objects-general.c`. However, that initialization was coded
as a macro to trick the style checker. This patch gets rid of that
macro and uses proper C99 struct initializer with designators.

fdbbd0e8af Turn port implementations into proper libraries (#1777)
This commit changes the concept of JerryScript port implementations
from a simple directory of C source files (which get injected among
the sources of `jerry-core`) into a proper static library (which
may be linked to an application together with `jerry-core`). As a
consequence, this commit introduces a new library to the
JerryScript component architecture: the sources of the default port
implementation form `jerry-port-default`.

Changes in more detail:

- The sources in `targets/default` are moved to `jerry-port/default`
  and are turned into a proper static library.
  - Actually, the default port implementation has two library
    variants, one that implements the bare minimum only
    (`jerry-port-default-minimal`) and one that has some extra
    functionalities specific to this implementation (the "full"
    `jerry-port-default`).
  - The new libraries have an interface header in
    `jerry-port/default/include`, which extends the common
    `jerryscript-port.h` API with functions specific to these
    libraries.
  - All non-standard port functions have now the
    `jerry_port_default_` prefix (this affects `jobqueue_init` and
    `jobqueue_run`).
  - The jobqueue implementation functions became config macro
    independent: it is now the responsibility of the linker to pick
    the needed objects from the library, and omit those (e.g.,
    jobqueue-related code) that are not referenced.
  - Build of the libraries can be controlled with the new
    `JERRY_PORT_DEFAULT` cmake option.

- The cmake option `PORT_DIR` is dropped, and `PORT_DIR/*.c` is not
  appended to `jerry-core` sources.
  - Instead, the `jerry` tool of `jerry-main` links to
    `jerry-port-default`, while `jerry-minimal` links to
    `jerry-port-default-minimal`.
  - `tests/unit-core` tests are also linked to
    `jerry-port-default-minimal`.

- Tools adapted.
  - `build.py` has `--jerry-port-default` instead of `--port-dir`.
  - `check-*.sh` have paths updated (`jerry-port/default` instead
    of `targets/default`).

- Miscellaneous.
  - Dropped `#ifndef`s from `jerryscript-port.h`. It is a public
    header of the `jerry-core` library, which means that it must
    not contain configuration-dependent parts (once the library is
    built with some config macros and the archive and the headers
    are installed, there is no way for the header to tell what
    those config macrose were).
  - Added documentation comments to the JobQueue Port API (in
    `jerryscript-port.h`) and to several default port
    implementation functions (in `jerry-port/default`).

0511091e8a Streamline copyright notices across the codebase. (#1473)
Since the project is now hosted at the JS Foundation we can move to unified copyright notices for the project.

Starting with this commit all future contributions to the project should only carry the following copyright notice (except for third-party code which requires copyright information to be preserved):

"Copyright JS Foundation and other contributors, http://js.foundation" (without the quotes)

This avoids cluttering the codebase with contributor-specific copyright notices which have a higher maintenance overhead and tend to get outdated quickly. Also dropping the year from the copyright notices helps to avoid yearly code changes just to update the copyright notices.

Note that each contributor still retains full copyright ownership of his/her contributions and the respective authorship is tracked very accurately via Git.

9915307bc0 Drop -gdwarf-4 from compiler flags (#1385)
`-g` is enough (most modern compilers use DWARF4 as default, at
least, e.g., GCC has switched from DWARF2 in 4.8), more future
proof (if a compiler moves to a newer version, it wont get forced
to a fixed older version), and less restrictive (some compilers
handle the "standard" `-g` only but don't understand its variants).

513d9f4c9c Sync cmake and build.py defaults (#1360)
* Cmake had LTO OFF, build.py had LTO ON by default. ON became the
  common setting.
* Cmake had snapshot save/exec OFF, build.py had them ON by
  default. OFF became the common setting.

d38ab71140 Improve the linking of libraries (#1338)
Although both jerry-libc and jerry-libm have configuration options
that enable/disable their build, in practice, only jerry-libc can be
replaced with the system (compiler-default) libc. If jerry-libm is
disabled, the build of jerry-main fails, as there is no way to
instruct the linker to link the system libm to the binary. (The
build system does have a way to pass flags to the linker, but those
flags are listed before the linked objects. For the references to
get resolved correctly, the libraries to be linked have to be
specified _after_ the objects.)

This patch adds the EXTERNAL_LINK_LIBS configuration option to
CMakeLists, which ensures that the specified libraries get
correctly passed to the linker. (E.g, replacing jerry-libm with
system libm becomes possible with
`JERRY_LIBM=OFF EXTERNAL_LINK_LIBS='-lm'`.)

Additionally, the patch also makes the following related changes:

* Removes the COMPILER_DEFAULT_LIBC configuration option, as it is
  (almost) always the opposite of JERRY_LIBC. Moreover, its name is
  misleading: its only role is to add `-nostdlib` to the linker
  flags.

* Makes use of transitive library dependencies: if a library has
  another library as dependency, and it is linked to a binary, its
  dependency is linked as well. Thus, jerry-libc, jerry-libm, and
  any external libraries are added to jerry-core as dependency, and
  then only jerry-core is linked to executables (cmake will take
  care of the rest).

* build.py and run-tests.py follow up the changes, along with some
  minor syntax changes.

* Moves static linking option to global CMakeLists, as unit test
  binaries should be linked the same way as jerry-main.

* Adds EXTERNAL_COMPILER_FLAGS and EXTERNAL_LINKER_FLAGS as last to
  the flag list, to allow user override of (nearly) anything.

The patch speculatively follows up the build system changes in the
mbed, riot-stm32f4, and zephyr targets.
