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.

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.
