## enet
- Upstream: http://enet.bespin.org

Files extracted from upstream source:
- all .c files in the main directory (except unix.c win32.c)

Important: enet.h, host.c, protocol.c have been slightly modified
to be usable by Godot's socket implementation and allow IPv6 and DTLS.
Apply the patches in the `patches/` folder when syncing on newer upstream
commits.
Three files (godot.cpp, enet/godot.h, enet/godot_ext.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 its functionality to IPv4 only.
