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.
