Some clients rely on Base64 padding characters (i.e., '=') to be present
in encoded SRTP key/salt strings to determine the length of the encoded
data. However, FreeSWITCH removes these characters before including the
encoded strings in the SDP. This causes those clients that rely on the
padding to truncate the encoded data and be unable to properly set up an
encrypted SRTP session.

This change introduces a channel flag named 'rtp_pad_srtp_keys'. When
this flag is enabled, FreeSWITCH includes the Base64 padding characters
in the SDP. This allows clients that rely on the padding to retrieve the
full key and salt values and successfully negotiate an SRTP stream with
FreeSWITCH.

When running "make swigclean" in mod_lua directory and trying to compile
mod_lua afterward, the build fails because the target mod_lua_wrap.cpp
doesn't exist. The target is wrongly called lua_wrap instead.

making all mod_lua
make[7]: Entering directory '/path/to/freeswitch-1.6.17/src/mod/languages/mod_lua'
  CXX mod_lua_la-mod_lua.lo
  CXX mod_lua_la-freeswitch_lua.lo
make[7]: *** No rule to make target 'mod_lua_wrap.cpp', needed by 'mod_lua_la-mod_lua_wrap.lo'. Stop.

Fix this by renaming lua_wrap to mod_lua_wrap.cpp.
