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.
The V.17 modem has been modified, so it will not clear the most recent
saved AGC value if long training is requested.
The T.38 gateway codec now has fillin implemented properly
Fixed VS2005 version of make_modem_filter
Fixed a couple of places where declaration and definition of functions do not have the same calling conventions. Only relevant for Win32 compiles.
