Zher Huei Lee e3e2f06324 Replacement of internal RegEx with PCRE2 
The pattern and replacement matching behaviour has been changed purely
due to the nature of switching to a standards-compliant library.

One mistake in the previous behaviour was that named groups didn't have
a number. This has been corrected.

As names are actually just an alias of numbered groups,
RegExMatch::get_name_dict() is now get_names() and is a dict
referring to the group number it represents.

Duplicate names are enabled and the with the first matching instance
used.

Due the lack of a suitable equivalent in PCRE2, RegExMatch::expand() was
removed.

  • Upstream: ?

TODO.

enet

Files extracted from upstream source:

  • all .c files in the main directory (except unix.c win32.c)
  • the include/enet/ folder as enet/ (except unix.h win32.h)
  • LICENSE file

Important: enet.h, host.c, protocol.c have been slightly modified to be usable by godot socket implementation and allow IPv6. Two files (godot.cpp and enet/godot.h) have been added to provide enet socket implementation using Godot classes. It is still possible to build against a system wide ENet but doing so will limit it's functionality to IPv4 only. Check the diff of enet.h, protocol.c, and host.c with the 1.3.13 tarball before the next update.
