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.

Replace DisplayData to DebuggerAction. The new class has only four type
options. Furthermore several functions returning with DisplayData is
changed to return with string.

This was needed for the VScode extension so we know in total howmany frames we have in the backtrace.

Sending the output to the debugger client, at the moment only the JS side prints are sent over.

Convert debug server port from a compile-time constant to a context
variable. This enables each engine instance (either running in the
same process or in different processes) to listen for connections
at different ports, i.e., multiple engines can be debugged at the
same time on the same machine.

Now the debugger generates a breakpoint for each function before
its first executable statement. This allows inspecting the function
arguments. Position (line and column) info is also added which
simplifies finding of anonymus functions. Several tests were
update to check more corner cases.

The debugger supports setting breakpoints, execution control (step, next, continue)
and getting backtrace. The communication is WebSocket-based, so a browser can
communicate with JerryScript without any intermediate application.
