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.

The existing logic overrides container metadata even in cases where the
container metadata must be trusted (e.g. HDR). The original spec had no
provision for specifying color volume, so many files rely on the
assumption of Rec. 709.

An update to the spec included a 'clv' field for explicitly signaling
that the container should be trusted in an existing bitfield in the
frame header, but the default of 0 from old encoders forces Rec. 709,
which would break any HDR stream. Because there is no place in DNxHR for
specifying a transfer function, DNxHR HDR files must include
container-level color information.

This patch maintains the existing behavior of choosing the 709 over the
601 matrix when container-level information is missing, and allows
container-level information to win if present.
