5a93a85fd0 avformat/mxfdec: fix last packet timestamps 
The current edit unit cannot be reliably determined for the last packet of a
video stream, because we can't query the start offset of the next edit unit
from the index. This caused missing timestamps for the last video packet.

Therefore from now on, we allow setting the PTS even if we are not sure of the
current edit unit if mxf_set_current_edit_unit returned a specific failure, and
the assumed current edit unit is the last.

Fixes last packet timestamp of:
ffprobe -fflags nofillin -show_packets tests/data/lavf/lavf.mxf -select_streams v

42a22d01d1 doc: reorganize developer.texi chapter hierarchy 
Previously, the Developer Documentation <ffmpeg.org/developer.html>
contained a single chapter, "1. Developer Guide," with all content under
that single chapter. Thus the document structure was one level deeper
and more complicated than it needed to be.  It differed from similar
documents such as /faq.html, which have multiple chapters.

Eliminate the single chapter, and promote each section underneath to
chapter, and each subsection to section. Thus content and relative
structure remains the same, but the overall structure is simpler.
Anchors within the page remain the same.
