This ensures that any processing between the MDCT and exponent extraction will
be using clipped coefficients.

For 9/10bit, it means we don't have to upscale to 16bit before
actual scaling or pixel format conversion, and thus a performance
gain.

EBML_STOP leaves matroska->current_id set. Then matroska_read_seek changes
the stream position without resetting current_id.  The next
matroska_parse_cluster  fails due to calculation of incorrect pos.  So clear
current_id when avio_seek happens in matroska_read_seek.

Without this, members that have been declare with the DECLARE_ALIGNED
macro don't show up at all in the generated documentation.

libavutil/opt.c:604:1: warning: missing braces around initializer [-Wmissing-braces]

The targets are now part of FATE and can be run as individual FATE targets.

This fixes this compilation warning, by making endptr a non-const
pointer, as required by strtol:
In function ‘udp_open’:
warning: passing argument 2 of ‘strtol’ from incompatible pointer type

This fixes building with --enable-small, by using the correct

In adjust_frame_information(), msc is incremented for each sfb in each
sub-window then compared against max_sfb which is for a single sub-window.

This resulted in frames using EIGHT_SHORT_SEQUENCE where the first few
sub-windows increment msc to a value that results in ms_mode == 2. Even
though only some of the bands are actually using Mid/Side.

aacenc: Implement dummy channel group analysis that just calls the single channel analysis for each channel.

PLD is present in ARMv5TE and later, which is checked for separately.

ogg_save() copies streams[], but doesn't keep track of free()'ed
struct members. Thus, if in between a call to ogg_save() and
ogg_restore(), streams[].private was free()'ed, this would result
in a double free -> crash, which happened when e.g. playing small
chained ogg fragments.

This means that precision is retained when scaling between sample
formats with >8 bits per component (48bit RGB, 16bit grayscale,
9/10/16bit YUV).

GNU make 3.81 apparently does not support order-only prerequisites
with pattern rules, and thus fails to create the tools directory
if it is missing.  Naming the objects explicitly in the rule makes
it work properly.
