Fix bugs accessing properties of AU (mostly logging calls) when the last AU of a stream has already been muxed and hence free-ed.

Add logic to correctly delay the addition of released Picture's to the
Picture free list so they can't be reused before all Pictures that might
reference them have also been released.

jpeg2yuv can read filenames from stdin too

Initial Fix attempt for broken handling of forcing P frames.

Ok - after discussion with James revert some of the argument sanity checking
by putting it back inside the ALTIVEC_VERIFY ifdef. Leave the one check
for 16x16/8x8 blocks present to avoid a repeat of the yuvdenoise debug session.

at Stefan's request (he is on travel for a while) administer first aid to
the program by changing it to use 16x16 search blocks rather than 32x32 blocks.
The accelerated SAD routines have a 16x16 limit. Altivec routines check for
this and will log a message and exit, but the MMX versions will simply crash
eventually.

Enable some of the sanity checks that were hidden inside '#ifdef ALTIVEC_VERIFY'
conditionals. In particular the requirement in sad_00 that 'h' be 8 or 16 was
being violated by yuvdenoise and the program was mysteriously coredumping.

IF "user input" (in this case a parameter from a user program into a library)
can cause a program to segfault THEN that condition SHOULD BE CHECKED and
a meaninful error given.

After enabling the checks the cause of the problem was immediately known:

**ERROR: [yuvdenoise] sad_00: h != [8|16], (32)

Update documentation - lingering references to jpeg-mmx

Aesthetic changes, use 'err' as a local variable rather than 'errno' (system
error), use filen() instead of hardcoding filedescriptor numbers

Add the y4mivtc executable.
