The -f and --generate-function-snapshot switch are added to the jerry-snapshot
command line tool so the entire javascript input can be interpeted and
loaded as a function snapshot. The function arguments must be given in
the command line.
Example:
echo "return a + b;" > myfunc.js
./jerry-snapshot generate -f "a, b" myfunc.js

The current module implementation resolves module paths relative to the
current working directory, but paths should be resolved relative to the
currently evaluated module/source.
This requires a change in the jerry_port_normalize_path port API
function, so that it also takes the current module path as an argument.
On the engine side, we now also create a module object for the main
script, so that we can properly identify the base path for other
modules.

When using ES6 modules it was not possible to identify which module
an error originates from.
This PR changes the error message to also include the file path using
the file:line:column format, and updates the source context printing for
unhandled exceptions to use the correct file.

- 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.

Removed 'jerry_parse_and_save_literals' and introduced
'jerry_get_literals_from_snapshot' instead which works
on snapshot buffers rather than source code. Added literal
saving feature to snapshot merge in the snapshot command
line tool. Also added missing 'jerry_cleanup()' calls to the
snapshot tool. Improved the console messages of the snapshot
tool.

There was quite some confusion about terminology around instances
and contexts. All the docs mentioned external contexts but
functions and types were referring to instances, and the relation
between these two concepts were not clear. This commit keeps
(external) context as the only surviving concept.

The `[jerry|ecma]_char_ptr_t` types are some old legacy that are
used quite inconsistently. Their `[jerry|ecma]_char_t *` variants
are used a lot more often, so it's better to stick to one form
throughout the code base.

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 the snapshot tool the files were opened
in text mode. However the snapshot files
are binary files thus it is advised to use the
binary mode when opening the files.
Specifying the binary mode is a must on Windows
platform otherwise the read/write operations
are inserting extra '\r' characters.
To make the tools consitent across OSes all
fopen are now opening files in binary mode.
Also update jerry-libc to accept the 'b'
modifier and add a test case where the JS
file uses CR-LF line endings.

In general, public headers should not have compiler-specific
constructs but both the core and the port headers have attributes,
which are non-standard. It's better to factor out such constructs
to a common place (a new header) and hide them behind macros, which
can then be defined on a per-compiler basis.
This patch moves the existing definitions of function attributes and
likely/unlikely builtins to the new header. At the same time, it
unifies the names of these attribute defines and where they are
used. Moreover, it touches on jerry-main and removes the uses of
`__attribute__((unused))` entirely and replaces them with the
elsewhere used `(void) ...` pattern.

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.

- After the message received the engine will call the cleanup and init

for a new client connection(rest of the work is the client's responsibility).
