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.

Under the cover of the debugger transport layer, allocation on the
engine's heap has been made available to the public. As there are
actually no restrictions on what the allocated memory can be used
for, the memory management functions better fit in the core part
of the API.

Closes #1805

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.

This patch adds a new finalize_cb callback to jerry_context_data_manager_t.
The callback is run as the very last thing in jerry_cleanup, after the VM has been torn down entirely.
There was already the deinit_cb, which is run while the VM is still in the process of being torn down.
The reason the deinit_cb is not always sufficient is that there may still be objects alive (because they still being referenced) that have native pointers associated with the context manager that is being deinit'ed.
As a result, the free_cb's for those objects can get called *after* the associated context manager's deinit_cb is run. This makes cleanup of manager state that is depended on by the live objects impossible to do in the deinit_cb. That type of cleanup can only be done when all values have been torn down completely.

Update documentation for jerry string to buffer function with suggestions to use substring. (#2174) (#2174)

In some use cases, you want to reliably copy jerry strings to buffer, even if it doesn't fit target buffer, but is acceptable to lose some bytes. In those cases, the documentation will now suggest using the substring function as an alternative instead.

Aborts are similar to exceptions except they are not caught by catch
and finally blocks. Callbacks should honor aborts as well and return
them without processing them. Aborts are never thrown by JavaScript
code.

In the future certain events such as out-of-memory condition may
also throw aborts.

Added two new api functions:
* jerry_parse_and_save_function_snapshot
* jerry_load_function_snapshot_at

The jerry_parse_and_save_function_snapshot function allows
creating snapshots from snapshot arguments and body source.

The jerry_load_function_snapshot_at function enables loading
back functions from a given snapshot as a JS function object.
