Summary:                    [patch] Loading chan_iax2.so allocates >100M RSS
Description: 
The main asterisk process resident memory usage jumps over 100 MB when
loading chan_iax2.so. The configuration file iax.conf is empty.

If this is not reproducible for other people, let's compare build
environment and libraries.

  Change mutex tracking so that it only consumes memory in the core mutex
object when it's actually being used.
  
  This reduces the overall size of a mutex which was 3016 bytes before
this back
  down to 216 bytes (this is on 64-bit Linux with a glibc-implemented
mutex).
  The exactness of the numbers here may vary slightly based upon how
mutexes are
  implemented on a platform, but the long and short of it is that prior to
this
  commit, chan_iax2 held down 98MB of memory on a 64-bit system for
nothing more
  than a table of 32767 locks.  After this commit, the same table occupies
a mere
  7MB of memory.
