Add missing #includes to headers and rename tox_old to tox_group.

Also, no longer #include the group code into tox.c. Instead, compile it
separately in tox_group.c. This is a bit less surprising to someone looking
around the code. Having some implementations in a .h file is certainly a bit
surprising to a disciplined C programmer, especially when there is no technical
reason to do it.
