FS-6450 [unimrcp] Update library

[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
