avcodec/Makefile: Fix opus parser dependency.
The opus.c file uses ff_celt_freq_range and ff_celt_freq_bands which are
defined in opustab.c. The opus parser needs to include that file to
avoid linker errors when not including the opus encoder/decoder.

avcodec/decode: reset codec on receiving packet after EOF in compat_decode
In commit 061a0c14bb57 ("decode: restructure the core decoding code"), the
deprecated avcodec_decode_* APIs were reworked so that they called into the
new avcodec_send_packet / avcodec_receive_frame API. This had the side effect
of prohibiting sending new packets containing data after a drain
packet, but in previous versions of FFmpeg this "worked" and some
applications relied on it.
To restore some compatibility, reset the codec if we receive a new non-drain
packet using the old API after draining has completed. While this does
not give the same behaviour as the old API did, in the majority of cases
it works and it does not require changes to any other part of the decoding
code.

arm/hevc_idct: fix compilation on Android
Compilation error "out of range" fixed for armeabi-v7a. Compilation failed
trying to build libvlc.aar for ARM7 android on ubuntu 16.04 host. Error
messages is "Offset out of range". The reason of the error is assembler LDR

doc/developer: revise mailing list section
The Developer Documentation had instructions to
subscribe to the ffmpeg-cvslog email list. But that is
no longer accurate. For the purposes in this section --
review of patches, discussion of development issues --
ffmpeg_devel is the appropriate email list. Some developers
may want to monitor ffmpeg-cvslog, but it is not mandatory.
This is v3 of this doc, based on discussion in thread
<https://ffmpeg.org/pipermail/ffmpeg-devel/2017-November/220528.html>
and in response to docs Maintainer comments in
<https://ffmpeg.org/pipermail/ffmpeg-devel/2017-December/221596.html>.
1. In doc/developer.texi, add a new section about
ffmpeg-devel, based on existing text from ffmpeg-cvslog
section regarding discussion of patches and of
development issues. Reflect wording from discussion at
<https://ffmpeg.org/pipermail/ffmpeg-devel/2017-November/221199.html>
but with copy-editing to make wording more concise.
2. In doc/developer.texi, rewrite the ffmpeg-cvslog section
to match the current usage of ffmpeg-cvslog. Some
developers choose to follow this list, but it is not
mandatory.
There are a lot of improvements possible to the
Developer Documentation page, beyond this refactoring.
However, making those improvements is a much bigger
and more difficult task. This change is "low hanging
fruit".

opus_pvq: do not compile encoding/decoding code if the encoder/decoder is disabled
This should save quite a bit of space if either has been disabled for size reasons.
Could just check if the encoding flag is set during runtime on every single location,
however the overhead of branch misses would somewhat decrease performance.
opus: add an option to toggle intensity stereo phase inversion
Due to a somewhat high volume of complains, phase inversion has
been made optional with RFC8251. This allows for better bass
frequency response when partially downmixing to play on systems
with an LFE speaker.
This decoder-side change, introduced in RFC 8251 (section 9), slightly
improves the decoded quality of 16kbps speech in Hybrid Mode.
Differences can be seen/heard in testvector05.bit, testvector06.bit,
and testvector12.bit in the RFC 6716/8251 testvectors found here:

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:

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.
