Favor draw_mouse option. Should simplify parsing, and make it more
robust.

Add documentation for options draw_mouse, framerate, and video_size.

In particular, fix trac ticket #1314.

In particular, do not upcase first word, do not use final dot, use a verb
to specify what the option does, sort entries by name, apply random
vertical align.

Improve rendering.

Create a dedicated options subchapter, rather than a subchapter for each
option.

This is more consistent with the rest of the docs. Also apply misc minor
fixes for improving rendering.

The syntax of the 'glob_sequence' pattern type is explained in the image2
manual section, so there is no need to replicate it here.

Also discourage the use of such deprecated pattern type by not showing
examples employing it.

Replace the syntax explanation with an use example of the 'glob' pattern
type.

Allow to override the default 'glob_sequence' value, which is deprecated
in favor of the new 'glob' and 'sequence' options.

The new pattern types should be easier on the user since they are more
predictable than 'glob_sequence', and do not require awkward escaping.

This also avoids a pointless cast.

This is limited to the chars that arent filtered by av_log() already
we might filter more aggressively if theres some case where this becomes
needed.

Fix bogus warnings of the kind:
option 'color' is ignored with source 'testsrc'

when the color value is not explicitely set and the filter is different
from "color".

This fixes build failures on debian/kfreebsd

The a.out object format does not allow aligning sections.
On OS/2 LD aligns sections to 16 bytes.

Renames the old test to allow using fate-nuv as group for all
nuv tests.

Set the transactionId to 0 to signal the server a return _result/_error
is not expected.

Solves the problems experienced with strict rtmp servers.

It expects maximum value to be 32767 but calculations in scale_vector()
which uses this function can give it ABS(-32768) which leads to wrong
result and thus clipping is needed.

Due to some mistake LPC vector for the first subframe was used for all
subframes instead of their own LPC vectors.

id3 v2.2 uses image format ("JPG","PNG") instead of mimetypes.

Currently, the attached picture is skipped because the format string
does not match a known picture mimetype.

This patch fixes this behaviour.
