added if condition  for g729 codec .  After installation bcg729 library from git repo , it helps to find right path.

To avoid repeated strcmp()s and make use of switch()'s optimised binary
lookup, we employ a second build step that preprocesses certain .c files
and uses gperf to substitute pseudomacros with their respective constant
hash value.

(cherry picked from commit db7537b1f0)

The redis onekey concepts is introduced to reduce traffic to redis
and redis notification traffic.
It modifies the current structure for one call in redis, which are
multiple keys with pre- and postfixes and the callid in between to
one key with the structure "json-<callid>". The value is a json
formatted string with the previous multi-key identifiers in it.
