* Add error handing in mod_freetdm for ftdm trace failures
* Allow freetdm signaling modules to specify a destroy function
* Added conditional forwarding to the freetdm gsm module
Just specify the conditional-forwarding-number gsm parameter in freetdm.conf.xml
* Added new 'gsm call' freetdm command for raw GSM calls which can be
used to enable/disabling network features (e.g call *93) without
having to resort to use a full originate that requires routing the
call somewhere when answered
* Miscelaneous cleanup of piggy coding style left over by one of the
previous authors -_-
Currently only enabled in the analog e&m module but any
signaling module can easily take advantage of it with a small
modification to the signaling module to set span->sig_release_guard_time_ms
* Rename option ringback-during-collect to immediate-ringback
* Allow regular ringback tone with immediate-ringback, not just a wav file
* Do not request full frame of data, just packet_len which is what we receive per IO interval
* Ignore user data when playing ringback tone
FTDM_SIGEVENT_UP was falling through to FTDM_SIGEVENT_PROGRESS_MEDIA, which
does (almost) the same, so no harm, but still fix it.

Portability fix for uClibc and other (linux) environments that lack execinfo.h.
ftdm_backtrace_walk() and related return FTDM_NOTIMPL and print a message
if backtraces are not available in the current environment.

Indicator in IAM message.
- ss7_iam_nature_connection_hex is the channel variable to carry
HEX value from/to IAM message
- X-FreeTDM-IAM-NATURE-CONN-HEX is the x-header string to carry
HEX value from/to sip invite message
- This IE is 8 bit hex, which turns into 2 chars
- Only Satellite indicator, Continuity check indicator, and Echo
control device indicator are supported. Spare value are not taken.
Spare value is always set to all zero.
- example:
To set 00010101 (bit H-A), set X-FreeTDM-IAM-NATURE-CONN-HEX string
value to 15 in the sip invite message to NSG.
When NSG send out sip invite, if the incoming IAM message comes with
Nature of Connection IE, NSG will put X-FreeTDM-IAM-NATURE-CONN-HEX
in the invite x-header. For example, if the IE value is 00001010 in
the IAM, NSG will send X-FreeTDM-IAM-NATURE-CONN-HEX with value string
of "0A".
- Two characters are madatory. "0A" must be specified rather than "A". If
invalid format or characters are found, this x-header will be ommited.
- Valid characters include 0-9, A-F, and a-f
Read the forward call indicator IE and print it into channel variable
ss7_iam_fwd_ind_hex. If this variable exists, put it in the x-header.
This implementation takes bits of A, CB, D, E, F, HG, I from the hex
value. Bits of KJ, L, P-M are not taken and set to 0.
The hex value is H-A-P-I, H is the highest bit to A, and next is P-I.
I is the lowest bit in the whole field, and H is the highest bit in
the whole field. Refer to Q.763 chapter 3.23.
