[apr] Backport APR_RING_FOREACH and APR_RING_FOREACH_SAFE macros to APR for unimrcp compatibility.
[unimrcp] configure.gnu - need full path, not relative path for library paths
[unimrcp] added uni_revision.h - couldn't get it to autogenerate from build
[mod_unimrcp] add better logging and error checking on module load. Currently dumps core on MRCPv1 TTS attempt
[mod_unimrcp] don't configure MRCPv1 session with a connection agent- causes crash
