FLV spec only has AVC end of sequence tag, and the EOS tag has a
CodecID as other video data packet. MPEG4 doesn't conformance to
the spec, but it's there for a decade. So only 'fix' the EOS tag
rather than remove it completely.

HLS segments may be MPEG-TS or fragmented MP4, so those (de)muxers are
required for reading/writing HLS media segments.

Fixes functionality with --disable-everything --enable-demuxer=hls
--enable-muxer=hls

libplacebo gained these exciting new functions upstream.

According to https://github.com/Intel-Media-SDK/MediaSDK/blob/master/doc/mediasdk-man.md#configuration-change.
Before calling MFXVideoENCODE_Reset, The application needs to retrieve
any cached frames in the SDK encoder.
A loop is added before MFXVideoENCODE_Reset to retrieve cached frames
and add them to async_fifo, so that dynamic configuration works when
async_depth > 1.

ISOBMFF (14496-12) made this field ('channelcount') in the
AudioSampleEntry structure non-template¹ somewhere before the
release of the 2022 edition. As for ETSI TS 126 244 AKA 3GPP
file format (V16.1.0, 2020-10), it does not seem contain any
references limiting the channelcount entry in AudioSampleEntry
or in its own definition of EVSSampleEntry.

fate-mov-mp4-chapters test had to be adjusted as it output a
mono vorbis stream, which would now be properly marked as such
in the container.

1: As per 14496-12:
   Fields shown as “template” in the box descriptions are fields
   which are coded with a default value unless a derived
   specification defines their use and permits writers to use
   other values than the default.

When building FFMPEG in the MSYS environment under Windows, one
must not use forward slashes ('/') for command-line options.  It
appears that the MSYS shell interprets these as absolute paths and
then automatically rewrites them into equivalent Windows paths.  For
example, the '/nologo' switch below gets rewritten to something like
'C:/Program Files/Git/nologo', and this obviously breaks the build.
Thankfully, most M$ tools accept dashes ('-') as well.

Many filters accept user-provided data that is cumbersome to provide as
text strings - e.g. binary files or very long text. For that reason such
filters typically provide a option whose value is the path from which
the filter loads the actual data.

However, filters doing their own IO internally is a layering violation
that the callers may not expect, and is thus best avoided. With the
recently introduced graph segment parsing API, loading option values
from files can now be handled by the caller.

This commit makes use of the new API in ffmpeg CLI. Any option name in
the filtergraph syntax can now be prefixed with a slash '/'. This will
cause ffmpeg to interpret the value as the path to load the actual value
from.

Callers currently have two ways of adding filters to a graph - they can
either
- create, initialize, and link them manually
- use one of the avfilter_graph_parse*() functions, which take a
  (typically end-user-written) string, split it into individual filter
  definitions+options, then create filters, apply options, initialize
  filters, and finally link them - all based on information from this
  string.

A major problem with the second approach is that it performs many
actions as a single atomic unit, leaving the caller no space to
intervene in between. Such intervention would be useful e.g. to
- modify filter options;
- supply hardware device contexts;
both of which typically must be done before the filter is initialized.

Callers who need such intervention are then forced to invent their own
filtergraph parsing, which is clearly suboptimal.

This commit aims to address this problem by adding a new modular
filtergraph parsing API. It adds a new  avfilter_graph_segment_parse()
function to parse a string filtergraph description into an intermediate
tree-like representation (AVFilterGraphSegment and its children).

This intermediate form may then be applied step by step using further
new avfilter_graph_segment*() functions, with user intervention possible
between each step.

Refuse to link uninitialized filters or initialize a filter twice.

Also, replace an AVFilterContext argument with a logging context+private
class, as those are the only things needed in this function.

Will be useful in future commits.
