The encoder has no delayed packets at the end of the encoding
process, so signaling this capability is unnecessary.
This also fixes an assertion failure introduced in 827d6fe73d, as
return values higher than 0 are not expected.

This patch removes a check which throws an error if
the log2 precinct width/height is 0. The standard allows
the first component to have 0 as the log2 width/height.
However, to ensure proper intialization of coding style,
an extra check has been added.

libopenjpeg2000 uses ceiling division while dividing tile
co-ordinates with the sample separation. Also, corrections
were made to the WRITE_FRAME macro.

Now we just use one ADTS raw frame to calculate the bit rate, it's
lead to a larger error when get the duration from bit rate, the
improvement cumulate Nth ADTS frames to get the average bit rate.
e,g used the command get the duration like:
ffprobe -show_entries format=duration -i fate-suite/aac/foo.aac
before this improvement dump the duration=2.173935
after this improvement dump the duration=1.979267
in fact, the real duration can be get by command like:
ffmpeg -i fate-suite/aac/foo.aac -f null /dev/null with time=00:00:01.97
Also update the fate-adtstoasc_ticket3715.

There is no reason to special-case writing a value of zero as uvlc
element as the generic code is perfectly capable of doing so.

Commits 957a593cd9 and
11828b8885 made the flv demuxer export
a certain flag as side data to be used by the nellymoser decoder for
mid-stream sample rate changes. It used a custom side data type 'F' that
was never officially documented.
Yet since 2215c39e94 (merged in commit
52c522c720) this information is exported
via the properly documented AV_PKT_DATA_PARAM_CHANGE side data.
The merge commit therefore stopped exporting the 'F' sidedata; yet the
changes in the Nellymoser decoder (which are now dead code (and would
become dangerous if lots of new side data types were added)) have not
been removed. This commit does this.

Following the same logic as 061a0c14bb, this commit turns the old encode API
into a wrapper for the new one.
Signed-off-by: James Almer <jamrial@gmail.com>
This commit follows the same logic as 061a0c14bb, but for the encode API: The
new public encoding API will no longer be a wrapper around the old deprecated
one, and the internal API used by the encoders now consists of a single
receive_packet() callback that pulls frames as required.
