This change adds a build option that allows adjusting the garbage
collection heap usage limit, which can be used to fine-tune how often
garbage collection should be triggered.

Previously after the library was build there was no easy way
to get back the information of how it was build.
This change adds a bit of CMake code to generate the
jerryscript-config.h file containing the default options
and adding the modified build options/features.

This patch unifies the recursion limit checking for RegExp, function call and JSON as well.
Until now the limit was only a counter which was increased/decreased at certain points.
This counter has been substituted with a numeric limit which allows to restrict the stack usage.
This patch fixes#2963 and resolves the closed#2258 issue.

There are quite a few configuration macros in the project.
As discussed in the #2520 issue there are a few awkward constructs.
Main changes:
* Renamed all CONFIG_DISABLE_<name>_BUILTIN macro to JERRY_BUILTIN_<name> format.
* The special JERRY_BUILTINS macro specifies the basic config for all es5.1 builtins.
* Renamed all CONFIG_DISABLE_ES2015_<name> to JERRY_ES2015_<name> format.
* The special JERRY_ES2015 macro specifies the basic config for all es2015 builtins.
* Renamed UNICODE_CASE_CONVERSION to JERRY_UNICODE_CASE_CONVERSION.
* Renamed ENABLE_REGEXP_STRICT_MODE to JERRY_REGEXP_STRICT_MODE.
* All options (in this change) can have a value of 0 or 1.
* Renamed ENABLE_REGEXP_STRICT_MODE to JERRY_REGEXP_STRICT_MODE.
JERRY_REGEXP_STRICT_MODE is set to 0 by default.
* Reworked CONFIG_ECMA_NUMBER_TYPE macro to JERRY_NUMBER_TYPE_FLOAT64 name and now
it uses the value 1 for 64 bit floating point numbers and 0 for 32 bit floating point
number.
By default the 64-bit floating point number mode is enabled.
* All new JERRY_ defines can be used wit the `#if ENABLED (JERRY_...)` construct to
test if the feature is enabled or not.
* Added/replaced a few config.h includes to correctly propagate the macro values.
* Added sanity checks for each macro to avoid incorrectly set values.
* Updated profile documentation.
* The CMake feature names are not updated at this point.

Introduce a new way of building: before any file is compiled
all source files are combined into a single C file and all
header files into a single H file (per subdir).
This new approach makes it possible to quickly integrate JerryScript
into other projects:
```
$ gcc -o demo demo.c jerryscript.c jerryscript-port-default.c -lm
```
To use the source generator run:
```
$ cmake -Bbuild_dir -H. -DENABLE_ALL_IN_ONE_SOURCE=ON
$ make -C build_dir generate-single-source
```
This will create the following files in the `build_dir`:
* jerryscript.c
* jerryscript.h
* jerryscript-config.h
* jerryscript-port-default.c
* jerryscript-port-default.h

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.

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.

None of the code paths have been tested for long and especially the
Freya code paths have been long abandoned. This patch:
- Merges Valgrind-Freya into Valgrind code path (there should be no
need to choose between them, Valgrind should work just fine).
- Removes leftover code (`VALGRIND_FREYA_CHECK_MEMPOOL_REQUEST` and
`valgrind_freya_mempool_request`).
- Adds `JMEM_` prefix to Valgrind-related macros (to correctly
leave the `VALGRIND_` prefix to Valgrind).
- Moves the definition of the Valgrind-related macros to a common
header to avoid duplication.
Note: Adding a CI job to perform Valgrind Memchecks is left for
follow-up as it turns out to be excessively slow (>50 mins for a
`--jerry-tests --jerry-test-suite` run, and even a simple
`--jerry-tests` may get terminated prematurely because of timeout
issues).

* Replace JERRY_JS_PARSER feature guard with JERRY_DISABLE_JS_PARSER
All feature guards of jerry-core are deciding about the inclusion
or exclusion of a feature based on the state (defined or undefined)
of a macro -- except for the JS parser guard, which requires
`JERRY_JS_PARSER` to be defined with a value of either 0 or 1. This
has some issues:
- The engine cannot be built with a "clean" compiler invocation,
i.e., without any `-D` command line macro definitions. This is
painful for targets that must use a different build system from
the project's own python/cmake-based one.
- Some build systems in targets and even some code in jerry-code
are already confused about the different semantics of
`JERRY_JS_PARSER`, and simply define it without a value and make
decisions based on the macro being simply defined or not.
This patch renames the guard to `JERRY_DISABLE_JS_PARSER` and makes
use of it in jerry-core based on its state, not based on its value.
As obvious from the guard name, the default for the JS parser is
that it is included in the build.
The patch also touches those targets in the repository that
explicitly defined the original macro (correctly or incorrectly).
* Make cppcheck verbose
Cppcheck can be quite slow sometimes, especially on Travis CI,
which has a "10 mins without output means failure" rule. As the
code base of the project grows, we start to undeterministically
fall over that limit. Thus, this PR makes cppcheck verbose to
ensure that it keeps Travis CI continuously fed with output.

Moved all public API headers under the `jerry-core/include`
directory. This makes installing all the public headers easier.
Also, should we have new public headers in the future, their
installation will be automatic, there will be no need to update the
build files. Moreover, this aligns better with the structure of
other libraries in the project (in those cases, public headers
always reside in `<library>/include`).
Moved all public API implementations under the `jerry-core/api`
directory. This cleans up the root directory of `jerry-core`,
moving all implementation code under "modules", i.e.,
subdirectories. This also makes the future splitting of the big and
monolithic `jerry.c` along features easier, if needed. (Debugger
and snapshot-related functions are already in separate sources.)
Notes:
* `jerryscript.h` is split up to separate header files along
feature boundaries. These new headers are included by
`jerryscript.h`, so this is not a breaking change but header
modularization only.
* `jerry-snapshot.h` is still under `jerry-core/api`, keeping it as
a non-public header.
* This commit also adapts all targets to the include path change.

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`).

All public headers should follow the pattern `jerryscript[-*].h`.
The `jerry-api.h` to `jerryscript.h` renaming has already happened
a while ago, now it's time for the port API header to follow.
This patch
* renames the public header file,
* updates all includes to use the new file name (in `jerry-main`,
in all the targets, and in the docs), and
* keeps `jerry-port.h` as a deprecated forwarding header to leave
some time for external users to follow up with this change.
As a related change, the header of the default port implementation
is also changed to `jerryscript-port-default.h`.

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.
