If a 183 with sdp response is receive without a To tag the sdp is not
negotiated. According to RFC 3261 section 12.1.2 while a To tag is required,
the client needs to still be able to handle the missing tag case for
backwards compatibility.

This patch, accepted by and applied to pjproject, makes it so if an incoming
180/183 with SDP comes in without a To tag it gets appropriately handled.

OSX does not support 'readlink -f' or 'sed -r'.  Replace readlink with
the GNU make macro 'realpath'.  Replace sed with grep in one place, cut
in the other.

Mac doesn't like the comparison of -1 to an enum, so store the result of
ast_sip_str_to_dtmf to an int so we can check for the negative return
value.  ast_sip_str_to_dtmf returns an int so this is only delaying the
implicit type cast.

test_pbx used raise without explicitly including signal.h.  On Mac for
some reason nothing else includes it.

test_logger checked if an unsigned int was negative.  Switch the
variable to 'int' so that error check can be effective.

Some net-snmp builds do not provide the RONLY declare, only
NETSNMP_OLDAPI_RONLY.  Map RONLY to NETSNMP_OLDAPI_RONLY to get around
this error.

It's impossible for gwtimeout or fdtimeout to be less than 0 because
they are unsigned int's.  Remove checks and unreachable branches.

This adds the printf attribute and changes 'fmt' from 'const void *' to
'const char *'.  This resolves a warning from some compiler for
vsnprintf needing a literal string for format.

Declare 'res' initialized to -1 to deal with earlier error paths that
could cause 'res' to be returned uninitialized.
