Added -install arg to linux dedicated servers, to automatically install dependancies and updates. Fix edge friction (at least when pm_edgefriction is 2 and not empty - can't break compat). Added getchannellevel csqc builtin. git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@5438 fc73d0e0-1445-4013-8a0c-d673dee63da5

/*

Threading:
|
|
When the main thread will harm the filesystem tree/hash, it will first lock fs_thread_mutex (FIXME: make a proper rwlock).
|
|
Worker threads must thus lock that mutex for any opens (to avoid it changing underneath it), but can unlock it as soon as the open call returns.
|
|
Files may be shared between threads, but not simultaneously.
|
|
The filesystem driver is responsible for closing the pak/pk3 once all files are closed, and must ensure that opens+reads+closes as well as archive closure are thread safe.
