Summary:                    [patch] callprogress and faxdetect not read when
building channel results in fax detection failure
Description: 
The faxdetect and callprogress attributes are not read when creating
channels with build_channels with channels/chan_dahdi.c, and therefore, the
following chan_dahdi.conf prevents fax detection from happening :
[channels]
#include "dahdi-channels.conf"
callprogress=yes
faxdetect=both
usecallerid=yes
callwaiting=yes
usecallingpres=yes
callwaitingcallerid=yes
threewaycalling=yes
transfer=yes
canpark=yes
cancallforward=yes
callreturn=yes
echocancel=no

Actually, it looks like the whole [channels] section should be read to
populate the conf variable before calling build_channels().

I'm not sure if it's the right way to solve this issue, and there is a
configuration workaround (see the additional information). The attached
patch does the following :
- make Asterisk read the [channels] section without building channels
first ;
- build a first version of the configuration in the base_conf variable ;
- build a new configuration from base_conf and actually call
build_channels() after reading the channel attribute.
