> This patch has rippled out from the original goal of getting better error messages from {{INTERNAL_OBJ}}.  I found that providing only a REF_DEBUG version of __ao2_ref and __ao2_alloc resulted in faster performance, so I've expanded this to all code with REF_DEBUG dual ABI.  REF_DEBUG no longer has an effect on ABI, it is only used to set reference debugging to enabled by default.  Reference debugging can be controlled in asterisk.conf, refdebug=yes|no in the options section.

> All test runs were done on my Linux Mint 17 workstation, with reference debugging disabled.  I watched TV during each run to ensure I wouldn't do anything to effect system load.  patch4 is the original scope of changes to __ao2_ref and __ao2_alloc, INTERNAL_OBJ and is_ao2_object.  patch5 is the full removal of REF_DEBUG dual ABI.
