pthreads not working/not used

[Yann Kaiser]

luke introduced recently pthreads support, but forgot to put hooks in the most important parts
I wrote a patch to that purpose, but it crashes at second auth try

putting that here so we have a better place to either
* fix the patch
* ditch pthreads

(zthread support is still present atm, but at configure time, pthread gets 'priority')

[Luke-Jr (luke-jr)]

For reference, I did this for several reasons:
- zThread is no longer maintained
- zThread is not available for any Debian
- pthreads is standard/built-in to any common OS

Removed from 0.2.8, here is the original patch.

[Luke-Jr (luke-jr)]

If you're going to disable it, please do so correctly: modify the configure script to never enable it, don't remove the code entirely...

[Luke-Jr (luke-jr)]

Please test 0.2.8 HEAD; it should work now (also re-enabled)...

Note that my machines are all still single-core, so REAL testing is much needed. :)

server crashes randomly when I try to login:
armagetronad-dedicated: tpp.c:63: __pthread_tpp_change_priority: Assertion `new_prio == -1 || (new_prio >= __sched_fifo_min_prio && new_prio <= __sched_fifo_max_prio)' failed.

client recording:
- Login attempt denied because server was recording too: "Your login process will be delayed [...]"
- Left the server
- Joined again: the request was still pending (is that behavior wanted??) -> inserted password
- When round finished the login didn't succeed
- Tried again to login, died, inserted password
- At round end server crashed

sorry for the (short) time you'll lose watching me playing, I couldn't resist XD
