Remove the 'state' variable of per-channel data, use active flag exclusively to track
open/close state.

Add misdn_activate_channel()/misdn_deactivate_channel() helper functions, rename old
one to _misdn_toggle_channel() (internal).

Add _nowait variant of channel de-/activation function, that just sends the mISDN request message.

ftmod_isdn: Use span trunk_mode to select default mode and print warning if final modes do not match.

Same as ftmod_libpri.

Store call CRV in caller_data.call_reference and use call private to hold the
FreeTDM channel object.

Remove isdn_data->channels_{local,remote,outbound}_crv arrays.

Allow (and force) inbound call state transition DIALTONE -> DOWN for
incoming RELEASE COMPLETE messages in NT mode.

Dialtone in NT mode works, everything else needs more testing.

Create new demo IVR XML and phrases. (New sound files needed.) Update phrase_en.xml to-be-recorded sound files.

FS-4453 --resolve this will now cause up to a 20 second timeout waiting for the response and the call will be blocking

ftmod_misdn currently returns len == 0 if the incoming message,
that triggered the read() call, does not contain any data.
Users of ftdm_channel_read() need to handle this case, or they
may possibly end up in an endless loop.

This patch reworks the ftdm_channel_read() handling in ftmod_isdn
and prevents it from entering an endless loop. The read error counter
is reset on first sucessful read w/ data.

FS-4373 --resolve this is probably the same issue nobody would file a bug about on the mailing list even after I begged them to from last weekend

implementations for platforms with slow floating point

FAX engine yet.

Our main version string is designed for release engineering purposes:
it matches file name conventions used for versioned tarballs and the
versions sort lexicographically while containing all pertinent
information.

With this commit we add in parentheses a more human-friendly rendering
of the version string: we spell out the meaning of each field and
render the datetime in RFC 822 notation.

Showing whether the git repository is clean at the time of build will
be useful, but currently something in our bootstrap/configure/early
make process is causing the tree to look unclean at just the wrong
moment and clean builds are showing up as unclean.

open a door to write video data
so it is possible to record a .fsv file
also possible to write to .mp4 with proper file format support

audio only at this time
video is possible when add a file_write_video interface to core
only tested/working with 8000hz at this time
