* librb is no longer a separately configured subproject.
* charybdis is now a standalone directory with a binary.
* Include path layout now requires a directory ircd/ rb/ etc.
Clean up spaces/tabs mixing mess (bleh), add some defaults for authd
stuff, and get rid of CHARYBDIS_SOMAXCONN (just define SOMAXCONN if it's
available...).
Default values for default_floodcount and default_ident_timeout are set
in s_conf.c. Remove code that checks for missing values in ircd.c.
Additionally, reset default_ident_timeout to 5 if an invalid value (i.e.
0) is provided.
they are ALL gone. all of this stuff is now determined at runtime via getrlimit(2).
- due to this, devpoll is broken. i'm not motivated to fix it at the moment.
