Enhancements to trace logging, include threads and context ID.
Changed default opal_conf.xml to allow more than just G.711 uLaw and not to clutter log file with debug logs.
Added to opal_conf.xml item for "disable-transcoding".
Updated build/buildopal.sh to use correct ./configure items for PTLib, allow for something other than standard install directory for PTLib/OPAL and be able to easily bind to a specific release of PTLib/OPAL.
Callbacks are invoked from ftdm_span_start/_stop().
I/O is started before SIG and shut down in reverse order.
This is needed for ftmod_misdn, to move the mISDN message handling
into a separate thread (solving the mISDN socket vs. FreeTDM API issues).
With these callbacks, the I/O thread can be started after the span I/O configuration
has been (successfully) completed and stopped before destroying the span.
NOTE: Both SIG and I/O callbacks are called with the span mutex locked,
so threads created or destroyed synchronously in either of the custom
start/stop functions, can not use ftdm_span_*() functions that lock
the span mutex (e.g. ftdm_span_get_channel_count()).

The --enable-builtin-tiff option appends libs/tiff-3.8.2/libtiff/libtiff.la
to LIBS, causing the AC_CHECK_LIB([jpeg]...) check to fail, because
libtiff.la does not exist at configure time.
Temporarily store tiff and jpeg libs in TIFF_-/JPEG_LIBS variables and
append them to LIBS after all library checks have run.
Example error output:
configure:20049: checking for jpeg_start_compress in -ljpeg
configure:20074: cc -o conftest -O2 -pipe -fno-strict-aliasing -L/usr/local/lib conftest.c -ljpeg -lm /usr/home/ports/net/freeswitch-core-devel/work/freeswitch-1.2.1/libs/tiff-3.8.2/libtiff/libtiff.la >&5

The len variable can, in certain situations (large burst of incoming non-SLIN audio),
exceed the size of the on-stack frame buffer, which causes ftdm_buffer_read_loop() to
overwrite the dt_buffer pointer.
Use ftdm_min() to make sure len (after conversion to SLIN units) isn't larger
than the frame buffer size.
Also adds are couple more code comments.

Do a "soft" wraparound with modulo, removes the ~0.5s tone glitch.
(Multiply ts.rate (samples) by two to match the offset unit (bytes, 2 per sample).)

Store the offset in the teletone buffer in the b-channel private data.
An NT-mode setup with ftmod_misdn showed severe (dial-)tone distortions
in a sound editor (330Hz sine wave phase errors), caused by
using a global teletone buffer offset.
Switching to a per-channel offset, that is advanced by the amount
of data actually written to the channel, removes (almost) all
distortions.
There is still a minimal phase error every ~500ms (audible) that
needs more investigating.

Might as well import these too...
ftdm_offset_of() - Get offset of member in structure.
ftdm_container_of() - Get pointer to enclosing structure from pointer to structure member.
