  h264_refs: make sure not to write over the bounds of the default ref list

Conflicts:
	libavcodec/h264_refs.c

This condition should be impossible and was checked for by asserts.
the asserts are moved up in this merge to gurantee that no out of array
access can happen even if the state is "impossible".
Also if such impossible states could somehow be created, that should
be dealt with and not silently ignored.

This reverts commit ca21116b.

Revert suggested by Jamal:
"Bad secondary effect i just noticed: Every time version.h is changed
 (git pull for example), anything that includes config.h will be
 recompiled. And that means pretty much every single file in the tree.
"

Avoid clash with version.h of the libraries.

Call ff_mpeg4_decode_picture_header() only when the decoder has the
MPEG4 codec id, not based on a vaguely related value of h263_pred.

Fixes invalid writes.

Simplify.

This should workaround an apparent mis-compilation with gcc 4.2 on BSD
The function is rarely called and not inlining should have no speed
effect

Some systems provide Perl without pod2man.

Also add appropriate dependency declarations for perl and texi2html.
