Revise tools scripts to be python3 compatible on win32 (#4856)
We introduce setup_stdio function to setup stdout/stderr properly.
For python <-> python pipe, we always use 'utf8'/'ignore' encoding for not lost characters.
For tty <-> python, we using native encoding with xmlcharrefreplace to encode, to preserve maximal information.
For python <-> native program, we use naive encoding with 'ignore' to not cause error

update_exclude_list with binary mode so that on win32 would not generate \r\n

run-test-suite.py: Handling skiplist properly on win32

Fixes #4854

Fixes test262-harness.py complain cannot use a string pattern on a bytes-like object with running test262 with python3

For reading/writing to file, we use 'utf8' /'ignore' encoding for not lost characters.
For decoding from process stdout, using native encoding with decoding error ignored for not lost data.
Execute commands also ignore errors
Fixes #4853

Fixes running test262-esnext failed with installed python3.9 on win32 with space in path
Fixes #4852

support both / \ in --test262-test-list arg

On win32.
python tools/run-tests.py  --test262-es2015=update --test262-test-list=built-ins/decodeURI/
python tools/run-tests.py  --test262-es2015=update --test262-test-list=built-ins\decodeURI\
should be both valid,
currently only --test262-test-list=built-ins\decodeURI\ are valid.

Support snapshot-tests-skiplist.txt on win32 by use os.path.normpath

Guard run-tests.py with timer.

All run-tests.py are finished in 30 minutes in normal situation.
May change the timeout by command line option

Move Windows CI to github actions
Define TERM colors for win32 properly

flush stderr.write stdout.write

On CI, the stderr are redirect to stdout, and if we don't flush stderr and stdout,
The output from stderr/stdout would out of sync.

`Testing new Date(-8640000000000000) and fixes date for win32`
So that the CI can passed

if sys.version_info.major >= 3: remove, as we do not support python2 anymore

Fixes compiling warnings/errors for mingw/gcc

Introduce JERRY_ZSTR_ARG macro to avoid jerryx_print_string, jerryx_print_byte, jerry_port_print_byte, strlen (#4982)
Replace usage of jerryx_print_byte, jerryx_print_string with jerryx_print_buffer.

As we now have JERRY_ZSTR_ARG, so we can take advantage of it

With this, the jerry_port_print_byte port api won't need any more
this reduced the port api surface

Update cppcheck (#5108)
Re-enable cppcheck CI job

Update cppcheck suppression list:
    The new version of cppcheck raises warnings for many potential
    issues that are guarded against, so those warnings have been
    supressed.

Handle realloc failures:
    - jerry-ext/util/sources.c
    - jerry-port/common/jerry-port-io.c

Refactor test-snapshot: move each test to separate functions like some
others already were.

Rename `handler` variables inside `main` of `test-api.c` as they
shadowed the `handler` function in the same file.

Update jerry-port and jerry-ext (#4907)
Notable changes:
  - Updated and the port API interface, new functions have been added
    and some have been changed. The port library is now cleaned up to
    not have any dependency on jerry-core, as it should be. The port library
    is now strictly a collection of functions that implement
    embedding/platform specific behavior.
  - The default port implementation has been split for windows and unix.
    Implemented port functions have been categorized and reorganized,
    and marked with attribute((weak)) for better reusability.
  - External context allocation has been moved to the port API instead
    of a core API callback. The iterface has also been extended with a
    function to free the allocated context. When external context is
    enabled, jerry_init now automatically calls the port implementation
    to allocate the context and jerry_cleanup automatically calls the port
    to free the context.
  - jerry_port_log has been changed to no longer require formatting to
    be implemented by the port. The reason beind this is that it was vague what
    format specifiers were used by the engine, and in what manner. The port
    function now takes a zero-terminated string, and should only implement
    how the string should be logged.
  - Logging and log message formatting is now handled by the core jerry library
    where it can be implemented as necessary. Logging can be done through a new
    core API function, which uses the port to output the final log message.
  - Log level has been moved into jerry-core, and an API function has
    been added to set the log level. It should be the library that
    filters log messages based on the requested log level, instead of
    logging everything and requiring the user to do so.
  - Module resolving logic has been moved into jerry-core. There's no
    reason to have it in the port library and requiring embedders to
    duplicate the code. It also added an unnecessary dependency on
    jerry-core to the port. Platform specific behavior is still used through
    the port API, like resolving module specifiers, and reading source file
    contents. If necessary, the resolving logic can still be overridden as
    previously.
  - The jerry-ext library has also been cleaned up, and many utility
    functions have been added that previously were implemented in
    jerry-main. This allows easier reusability for some common operations,
    like printing unhandled exceptions or providing a repl console.
  - Debugger interaction with logged/printed messages has been fixed, so
    that it's no longer the port implementations responsibility to send
    the output to the debugger, as the port should have no notion of what a
    debugger is.  The printing and logging functions will now pass the
    result message to the debugger, if connected.
  - Cleaned up TZA handling in the date port implementation, and simplified
    the API function prototype.
  - Moved property access helper functions that use ASCII strings as
    keys from jerry-ext to the core API.

Rework the public API (#4829)
Related to #4186.

Some notable changes:
  - The term 'Error' now strictly refers to native Error objects defined in
    the ECMA standard, which are ordinary objects. All other uses of
    'error' or 'error reference' where the term refers to a thrown value is
    now called 'exception'.

  - Simplified the naming scheme of many String API functions. These functions
    will now also take an 'encoding' argument to specify the desired
    encoding in which to operate.

  - Removed the substring-copy-to-buffer functions. These functions
    behaved awkwardly, as they use character index to specify the
    start/end positions, and were mostly used incorrectly with byte
    offsets instead. The functionality can still be replicated with
    other functions if necessary.

  - String-to-buffer functions will no longer fail if the buffer is not
    sufficiently large, the string will instead be cropped.

  - Fixed the usage of the '_sz' prefix in many API functions. The term
    'sz' means zero-terminated string in hungarian notation, this was
    used incorrectly in many cases.

  - Renamed most of the public API functions to have shorter, more on-point
    names, rather than the often too long descriptive names. Functions are now
    also grouped by the type of value they operate on, where this makes
    sense.

Refactoring time-related default port implementations (#4513)
In the non-Windows code paths:
- New approach to compute TZA without the need for GNU-specific
  `struct tm.tm_gmtoff`.
- Always using `usleep` to sleep. (No real need for `nanosleep` as
  port API has sleep granularity of milliseconds.)
- Not checking for "time.h" at build configuration time as that
  header is mandated by the C standard.
- Not checking for "unistd.h" at build configuration time as that
  header is mandated by the POSIX standard (the default port is
  targeting POSIX systems -- and Windows).
- Fixing some macro guards.

Drop the minimal variant of the default port implementation (#4331)
The minimal variant became quite meaningless lately. There were two
port APIs originally that had extra functions in the default port
in addition to the core-mandated implementations: the I/O and
Termination port APIs. However, the extra Termination API code was
removed a year ago, leaving some minimal extension in the I/O port
only. As the overhead of the extension is negligible, it is not
worth maintaining two library variants.

Therefore
- this commit removes the minimal variant of the default port lib,
- rewrites uses of the minimal variant to use the variant with the
  I/O extension, and
- updates targets where I/O port code was copy-n-pasted.

Resolve module paths relative to the current module (#2976)
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.

3f6599c358 Add a "single" source/header file generation and build mode (#2790)
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

In the previous approach `jerryx_port_handler_print_char` was implemented
in by the jerry-default-port. This implementation however required the
jerry-ext handler header file which created a requirement in the
jerry-default-port for the jerry-ext headers.

77767c2161 Add pkg-config metadata files for libraries (#2680)
Should core, ext, libm, and/or port libraries be properly installed
on some system, help compilation and linking against them by
providing standard `.pc` files, which can be picked up by
pkg-config.

3afc4b0b85 Change jerry_port interface to allow for a correct implementation of timezones. (#2540)
The previous jerry_port interface did not allow timezones to be handled correctly,
even if the host system was up to the task. This PR changes the jerry_port interface
to allow a completely correct implementation to exist, and provides one (for Linux/BSD
systems) in default-date.c.

Fixes #1661
