* 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.
If there are holes in the auth_providers ID numbers, the array allocated
based on list length won't be large enough to handle all the IDs.
(auth->data could be converted to a dlink_list)
* long is too small on 32-bit systems, use unsigned long long if we want
to check for out of range values
* UINT32_MAX is a valid cid, and 0 isn't
* make auth->cid a uint32_t not uint16_t
Iteration is the primary thing done on these, so using a dictionary
doesn't help a lot. Furthermore (and most importantly), they are not
safe to delete from.
It's a bit of a hack, but better than before. Rather than rehashing
(which could get us into an endless loop), we now segregate the
configuration phase (creating entries ircd-side in case we restart authd
later) and sending phases (when configure_authd() is called). Since we
have to call configure_authd() no matter what (to send timeouts etc.)
and we have to send this data to configure authd anyway, and sending
duplicate data is bad, this is the only way I can think of for now.
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...).
Provider ID's are now assigned dynamically at load-time. To accomodate
this, there is now a lookup system for finding providers by name (all
providers have names as well).
Provider status (done, running, not run) is now attached to the
provider-specific data of the client. A reference count of auth
instances is kept in the auth_client struct to determine if a client is
done or not.
This also moves a lot of the logic for manipulating provider data into
into the provider.h header for inlining (no point in a function call for
these simple accessors).
