Spandspi's FAX engine now gives separate size and resolution information about
...
the images on the line and the images in the file. The ties in with the recent
addition of image resizing and flattenign for colur images.
mod_spandsp has been changed to make use of the additional information.

Some cleanups of FAX modem tone handling

T.31 now has basically functional T.38 mode - needs more testing, though
...
Various modules which lacked routines to get at the sub-structures now
have them.
The tests have been tweaked so they only access internals where essential.

Relaxed the constraints for declaring a clean end of call on FAX receive. If we
...
get an EOP, we no longer worry whether the final stages tidy up. This helps
tolerate the increasing number of VoIP calls which hang up before the audio has
flushed down the line.
A few little cleanups.

Add image squashing feature to the FAX engine so a superfine image or fine
...
image can be sent to a machine which has those resolutions inhibited.

Some tweaks to spandsp tests. Make spandsp write TIFF files more like the

TIFF/FX spec says, even though no software seems to care.

This should have moved us from tiff-3.8.2 to tiff-4.0.2 . The windows builds

will need rechecking.

Changes to the signaling tone detector to detect concurrent 2400Hz + 2600Hz
...
tones. This passes voice immunity and other key tests, but it bounces a bit
when transitions like 2400 -> 2400+2600 -> 2600 occur. Transitions between
tone off and tone on are clean.
