The previous code dependent on the input buffer matching the
buffer that has been provided by yadifs get_buffer.
The API does in now way gurantee this though its often true.
This fixes some out of array reads.
The regression test checksums change due to "out of picture" values
being initialized differently.
There should be no visual difference in the filters output

dvbsub: fix encoding of termination packets.
The old code generates a termination packet with the same regions as the
start packet and page_state set to "only what changed"; the result is
that the termination packet is decoded as identical to the start packet.
The new code does as found in some DVB broadcasts: produce a packet with
no regions. This is done by expecting num_rects to be 0 rather than
using a flip-flop. ffmpeg.c is updated accordingly.

mpegvideo: reduce excessive inlining of mpeg_motion()
The main benefit of inlining this function is from constant
propagation for the 'field_based' argument. Instead of inlining
all calls, create two versions of the function for field_based
values of 0 and 1.

mpegvideo: convert mpegvideo_common.h to a .c file
This file defines a single, huge function, MPV_motion(), which
although being declared inline is not actually inlined by the
compiler (for good reason). There is thus no sense in defining
this function in a header file, resulting in multiple copies of
it in the final library.

avconv: maintain sync on lavfi outputs.
Before this commit, poll_filters() reads all frames available on each
lavfi output. This does not work for lavfi sources that produce
an unlimited number of frames, e.g. color and similar.
With this commit, poll_filters() reads from output with the lowest
timestamp and returns to wait for more input if no frames are available
on it.

g723_1: clip argument for 15-bit version of normalize_bits()
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.

build: change checkheaders to use regular build rules
Many compilers need special flags to compile *.h files as regular
source code, if they will do so at all. Rather than hoping all
compilers will have such a flag and adding mappings for it, create
wrapper .c files for test building single headers.
This allows using the regular rule for compiling C files without the
need for special flags, and it also provides proper dependency tracking
for these objects.

rtmp: Add support for subscribing live streams
When streaming live streams using the Akamai, Edgecast or Limelight CDN,
players cannot simply connect to the live stream. Instead, they have to
subscribe to it, by sending an FC Subscribe call to the server.
checkheaders: Fix directory creation in out-of-tree builds.
checkheaders wasn't creating folders as needed, so if it was run

it tried to compile headers inside the ARCH folders.
