This commit brings in the changes that were living out on the
svn/asterisk/team/sruffell/asterisk-1.4-transcoder branch. codec_dahdi.c now
always uses signed linear as the simple codec so that a soft g729 codec will
not end up being preferred to the hardware codec. There are also changes to
allow codec_dahdi.c to feed packets to the hardware in the native sample size of
the codec. This solves problems with choppy audio when using G723.

Replace a bunch of if defined checks for Zaptel/DAHDI through several new defines in dahdi_compat.h. This removes a lot of code duplication. Example from bug:
#ifdef HAVE_ZAPTEL
fd = open("/dev/zap/pseudo", O_RDWR);
#else
fd = open("/dev/dahdi/pseudo", O_RDWR);
#endif
is replaced with:
fd = open(DAHDI_FILE_PSEUDO, O_RDRW);

release. Codec dahdi no longer functions with the transcoder interface in
zaptel at this time (which the last zaptel release was 1.4.11).
NOTE: Still needs an update to the configure script to make sure that
codec_dahdi is only built if the new transcoder interface is present in the
drivers.
