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.

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.
