Important: enet.h, host.c, protocol.c have been slightly modified
to be usable by godot socket implementation and allow IPv6.
Apply the patch in the `patches/` folder when syncing on newer upstream

Apply the patches in the `patches/` folder when syncing on newer upstream
commits.
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.
