  Ported ast_fax_caps_to_str() to 10, not sure why it wasn't already here.
  
  This function prints a list of caps instead of a hex bitfield.

  Fixup a race condition in res_fax.c where FAXOPT(gateway)=no will
  turn off the gateway but the framehook is not destroyed.
  
  this problem happens when a gateway is attempted in the dialplan and
  the device is not available i may want to do fax to mail in the server
  it will not be allowed.
  
  instead of checking only AST_FAX_TECH_GATEWAY also check gateway_id
  
  Reverts 338904
  
  Fix some white space.

0f0956e67a Fax gateway functionality (i.e. translating between a T.30 terminal and a T.38
terminal). Can be enabled on a channel by setting FAXOPT(gateway)=yes in the
dialplan.

Big thanks to irroot for porting this code to use the framehooks api.

32d43ebe19 When a error in T.38 negotiation happens or its rejected on a channel the
state of the channel reverts to unknown this should be rejected.
 
 this is important for negotiating T.38 gateway see #13405

 This patch adds a option T38_REJECTED that behaves as T38_DISABLED except it reports state rejected.

 Trivial Change to res_fax to honnor UNAVAILABLE and REJECTED states.

c26c190711 Asterisk media architecture conversion - no more format bitfields
This patch is the foundation of an entire new way of looking at media in Asterisk.
The code present in this patch is everything required to complete phase1 of my
Media Architecture proposal.  For more information about this project visit the link below.
https://wiki.asterisk.org/wiki/display/AST/Media+Architecture+Proposal

The primary function of this patch is to convert all the usages of format
bitfields in Asterisk to use the new format and format_cap APIs.  Functionally
no change in behavior should be present in this patch.  Thanks to twilson
and russell for all the time they spent reviewing these changes.

d40ccb8a7b Fix bug with 'F' option for ReceiveFAX and SendFAX.
Skipping the call to set_t38_fax_caps() caused the FAX session
details to not be marked as supporting audio FAX either... the
function's name is a bit misleading. This patch restores the
single bit of non-T.38 behavior from that function when audio
mode is forced.

e4ec545e59 Rename the SendFAX/ReceiveFAX 'force audio' option.
The recently added option to disable usage of T.38 for a single
session should have been named 'F' for 'force audio', since that
is really what the user is asking to happen (and it's a positive
option instead of a negative option that way).

2a7500021e Add ability to disable T.38 usage for specific SendFAX/ReceiveFAX sessions.
Sometimes during troubleshooting it can be useful to disable T.38 usage in order
to narrow down a problem. This patch adds an 'n' option to SendFAX and ReceiveFAX
so that can be done without having to disable T.38 usage entirely for the peer
that Asterisk is communicating with.

(inspired by trying to assist Bryant Zimmerman on asterisk-users)

c149b851b3 This commit contains several changes to the way output channel variables are handled.
FAX output channel variables will now match the values reported by FAXOPT() and should be set in all failure and success cases.

This commit also contains a few modifications to the way FAXOPT() variables are populated in a few spots and fixes for some reference count leaks of the session details structure in some failure cases.

Also found and fixed more cases where FAXOPT(status) may not have gotten set.

13f523731a Update res_fax and res_fax_spandsp to be compatible with Fax For Asterisk 1.2.
The fax session initilization code for T.38 faxes has been rewritten. T.38 session initialization was removed from generic_fax_exec, and split into two different code paths for receive and send.  Also the 'z' option (to send a T.38 reinvite if we do not receive one) was added to sendfax.

In the output of 'fax show sessions', the 'Type' column has been renamed to 'Tech' and replaced with a new 'Tech' column that will report 'G.711' or 'T.38'.

Control of ECM defaults has been added to res_fax

A 'fax show settings' CLI command has been added.

Support of the new AST_T38_REQUEST_PARMS control method request to handle channels that have already received a T.38 reinvite before the FAX application is start has been added.

Support for the 'fax show settings' command has been added to res_fax_spandsp and handling of the ECM flag has been slightly altered.

42577406fd Improve handling of T.38 re-INVITEs that arrive before a T.38-capable
application is executing on a channel.

This patch addresses an issue found during working with end-users
using res_fax. If an incoming call is answered in the dialplan, or
jumps to the 'fax' extension due to reception of a CNG tone (with
faxdetect enabled), and then the remote endpoint sends a T.38
re-INVITE, it is possible for the channel's T.38 state to be
'T38_STATE_NEGOTIATING' when the application starts up. Unfortunately,
even if the application wants to use T.38, it can't respond to the
peer's negotiation request, because the AST_CONTROL_T38_PARAMETERS
control frame that chan_sip sent originally has been lost, and the
application needs the content of that frame to be able to formulate a
reply.

This patch adds a new 'request' type to AST_CONTROL_T38_PARAMETERS,
AST_T38_REQUEST_PARMS. If the application sends this request, chan_sip
will re-send the original control frame (with
AST_T38_REQUEST_NEGOTIATE as the request type), and the application
can respond as normal. If this occurs within the five second timeout
in chan_sip, the automatic cancellation of the peer reinvite will be
stopped, and the application will 'own' the negotiation process from
that point onwards.

This also improves the code path in chan_sip to allow sip_indicate(),
when called for AST_CONTROL_T38_PARAMETERS, to be able to return a
non-zero response, which should have been in place before since the
control frame *can* fail to be processed properly. It also modifies
ast_indicate() to return whatever result the channel driver returned
for this control frame, rather than converting all non-zero results
into '-1'. Finally, the new request type intentionally returns a
positive value, so that an application that sends
AST_T38_REQUEST_PARMS can know for certain whether the channel driver
accepted it and will be replying with a control frame of its own, or
whether it was ignored (if the sip_indicate()/ast_indicate() path had
properly supported failure responses before, this would not be
necessary).

This patch also modifies res_fax to take advantage of the new request.

In addition, this patch makes sip_t38_abort() actually lock the
private structure before doing its work... bad programmer, no donut.

This patch also enhances chan_sip's 'faxdetect' support to allow
triggering on T.38 re-INVITEs received as well as CNG tone detection.

43d922b5a6 Improve handling of values supplied to FAXOPT(ecm).
Previously, values that began with whitespace were silently treated as 'no',
and all non-'yes' values were also treated as 'no'. Now the supplied value
is specifically checked for a 'yes' or 'no' (or equivalent) value, after skipping
leading whitespace. If the value is not valid, then a warning message is generated.
