These build as of FS-4265 being fixed.

Languages are installed at /usr/share/freeswitch/lang so that they can
be referred to by the user's configuration in /etc/freeswitch.  As a
Debian package user isn't going to have access to `make vm-sync` these
files need to be readily available somewhere.

On a GNU/Linux system -g3 and -ggdb3 should produce the same result
under gcc, but clang only recognizes -g3.

Previously mod_xml_cdr would only make its directory if log-dir was
not specified.  The behavior now matches that of mod_json_cdr.

FS-5084 There is only one thing I can see that might be the case, try this patch [bounty payable via paypal@freeswitch.org]

adding other kinds of image (specifically RTP and TCP/TPKT).

FS-5068 --resolve this was an edge case assert in a DNS error.  You may want to check that you have valid DNS servers but this should stop the crash

libzrtp strings are weird, and we were previously misusing the
function zrtp_zstrcpyc.  We can't use ZSTR_GV because it does insane
things and causes an array-bounds warning on gcc 4.7.  So we have to
take matters into our own hands and setup the string correctly and
copy data into it.

Because we were doing it wrong, people would get weird pseudo-random
single-character names for the zrtp cache file, and the file would end
up in the wrong place.  Now that this is fixed, users will need to
locate and move their zrtp cache file to their db_dir and name it
"zrtp.dat" if they wish to keep their current ZRTP cache.

mod_voicemail: add extra param inside the MWI event to know if it was fired because of a new message, or other reason
