Important: Some files have been modified by Godot developers so that they work
for all platforms (especially UWP). Check the diff with the 1.3.13 tarball
before the next update.
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.
