b10eb8758b Disable the H.323 proxy again - it's too buggy to be supported option

cedc0276dc Import H.323 proxy of IPFilter 3.4.25. Upon closer examination, 
the QNX licence seems to be allow both non-commercial and commercial
use actually.

According to Darren, the H.323 proxy code is buggy ATM, but is imported
here for reference anyway.

a180cee23b Pool deals fairly well with physical memory shortage, but it doesn't 
deal with shortages of the VM maps where the backing pages are mapped
(usually kmem_map).  Try to deal with this:

* Group all information about the backend allocator for a pool in a
  separate structure.  The pool references this structure, rather than
  the individual fields.
* Change the pool_init() API accordingly, and adjust all callers.
* Link all pools using the same backend allocator on a list.
* The backend allocator is responsible for waiting for physical memory
  to become available, but will still fail if it cannot callocate KVA
  space for the pages.  If this happens, carefully drain all pools using
  the same backend allocator, so that some KVA space can be freed.
* Change pool_reclaim() to indicate if it actually succeeded in freeing
  some pages, and use that information to make draining easier and more
  efficient.
* Get rid of PR_URGENT.  There was only one use of it, and it could be
  dealt with by the caller.

75c5a16cfc Enforce a lower bound of 32 for tcp_mssdflt. 
This avoids kernel crashes when we don't handle nonsensial values
like 0 gracefully. Better check here once beforehand than having to
check for non meaningful values in time critical paths (like tcp_output).

tcp_now wrapping is handled correctly).
