movtextdec: Don't emit errors for normal duration-end packets.
The logic here was off. If the packet size is exactly two, then
it's a well-formed empty subtitle, used to mark the end of the
duration of the previous subtitle.

srtenc: Add timing-less "subrip" encoder.
Unsurprisingly, if a timing-less subrip decoder is desireable, an
encoder is as well. With this in place, we can move on to remove
the use of the old encoder/decoder with embedded timing and move
all timing handling the (de)muxer where they belong.

srtdec: Add timing-less "subrip" decoder.
After various discussions, we concluded that, amongst other things,
it made sense to have a separate subrip decoder that did not use
in-band timing information, and rather relied on the ffmpeg level
timing.
As this is 90% the same as the existing srt decoder, it's implemented
in the same file.

LICENSE: correct incorrect claims on *GPL incompatibility
There are currently no statements from any person qualified in the art
of law about the LGPL compatibility of the libfaac license and others.
Furthermore their is no consensus about their compatibility amongth
people not qualified in the art.
Also of interrest may be that ubuntu distributes and links libfaac

rtmp: Add support for SWFVerification
Specifies how the server verifies client SWF files before allowing the
files to connect to an application. Verifying SWF files is a security
measure that prevents someone from creating their own SWF files that can
attempt to stream your resources.

rtmp: Do not send _checkbw calls as notifications
The _checkbw calls were changed to use transactionId 0 in commit 82613564 so that servers would not return _result/_error about it.
While this is the strict interpretation of the spec, there are
servers that return _error about it, even if transactionId was 0.
The latest version of EvoStream Media Server (the commercial version
of crtmpserver) behaves properly as described, i.e. returning an
_error normally but not returning anything when using transactionId
0. The latest version of crtmpserver (right now at least) doesn't
behave like this though, it returns an error even if transactionId
was 0.
There are also other servers that return errors even if transactionId
is set to 0. Therefore set a proper transaction id so that the invoke
can be tracked and the error properly ignored instead.

This function is always called with a non-negative argument, so
those special cases are not needed. In the places the argument
might be zero, the return value for a zero argument does not matter
since it would then be used to scale an array full of zeros.

lavfi: use min_perms and rej_perms for out pads.
There are several reasons for doing that:
1. It documents the code for the reader and helps find
inconsistencies and bugs.
2. For rej_perms, it guarantees the change will be done
even if the output reference can be created by several
code paths.
3. It can be used to predict cases where a copy will,
or will not happen and optimize buffer allocation
(for example not request a rare direct-rendering buffer
from a device sink if it will be copied anyway).
Note that a filter is still allowed to manage the permissions
on its own without using these fields.

lavf: probe PGS subtitles definition.
The resolution is in the packets, so decoding must happen.
Since most other formats do not set the dimension, make it
a special case for PGS. If other codecs were to have the

dvdsubenc: make it usable for transcoding.
DVD subtitles packets can only encode a single rectangle:
if there are several, copy them into a big transparent one.
DVD subtitles rely on an external 16-colors palette:
use a reasonable default one, stored in the private context,
and encode it into the extradata, as specified by Matroska.
TODO: allow to change the palette with an option.
Each packet can use four colors out of the global palette.
The old logic was to map transparent colors to the color 0
and all other colors to 3, 2, 1, cyclically in descending
frequency order, completely disregarding the original color.
Select the "best" four colors from the global palette, according
to heuristics based on frequency, opacity and brightness, and
arrange them in standard DVD order: background, foreground,
outline, other.
TODO: select the alpha value more finely; see if CHG_COLCON can
allow more than 4 colors per packet.
Note that the symbols used to run the hardware decoder in asynchronous mode
has been marked as deprecated and will be dropped at a future version dump.
