rtpdec: Remove an outdated todo comment

This comment was added in e309128f, in 2002, and has been brought
along since then more or less unmodified.

The first point of the todo was implemented in dbf30963 in 2006,
the second one is not relevant to rtpdec.c (brought along from
rtp.c in 8eb793c4 in 2008) but would be more relevant to the
rtp muxer, although it isn't a good idea anyway.

ZeroCodec: Flip output

The initial testing of the VFW binary codec was flawed,
likely due to an AviSynth bug.

Re-testing using VirtualDub and various professional editing
applications has revealed it should have been flipped.

build: fix 'clean' target

This fixes removal of TOOLS as well as HOSTPROGS declared in the
top-level Makefile.  The clean target in common.mak needs to be
eval'd since the variables used within are reset for each library.

Make LOCAL_ALIGNED syntactically similar on all systems

This changes the LOCAL_ALIGNED definition on systems where
DECLARE_ALIGNED is used so it matches the manual alignment
case, ensuring invalid use will not compile on x86 only to
fail on everything else.

swfdec: do better validation of tag length

Avoids trying to read a packet with 0 or negative size.
Avoids a potential infinite loop due to seeking backwards.

Partially based on a patch by Michael Niedermayer.
swfdec: cosmetics: fix indentation
lavr: clarify documentation for avresample_get/set_matrix()
lavr: temporarily store custom matrix in AVAudioResampleContext

This allows AudioMix to be treated the same way as other conversion contexts
and removes the requirement to allocate it at the same time as the
AVAudioResampleContext.

The current matrix get/set functions are split between the public interface
and AudioMix private functions.
x86inc: support stack mem allocation and re-alignment in PROLOGUE

Use this in VP8/H264-8bit loopfilter functions so they can be used if
there is no aligned stack (e.g. MSVC 32bit or ICC 10.x).

rtpdec: Improve some comments

The previous comment about the buffer was wildly inaccurate and
misleading.
