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.

- Fix cases where a function parameter binding is redeclared inside a parameter initializer eval
- Fix cases where a let- or function arguments binding is redeclared inside a function block because
there is a declaration in a function parameter initializer eval
- Also remove the ECMA_PARSE_CHAIN_INDEX_SHIFT macro, added a debugger_eval_chain_index named field to the jerry context instead

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.

The same data is returned for the script and all of its functions,
including those which are created by an eval call.

In some parts of Proxy internal methods the compiler can do a bit of
tail call optimalization which would be ok, but the current stack limit
check framework in Jerry uses the stack pointer to calculate the stack depth.
This way of stack depth calculation is affected by the tail call optimalization
(as the stack does not increase).
By disabling the tail call optimalization at given points the stack limit calculation
will work as expected. This causes a bit of stack overhead, but the Proxy in it self
is a fairly big chunk of code and this stack limit would only be relevant if the Proxy
already does recusion which already very edge case.
The stack limit (--stack-limit=..) should be enabled to correctly report such stack
depth errors.
