28df0151b6 configure: Add a dependency on vc1_decoder from vc1_parser
This fixes builds with vc1_parser enabled without vc1_decoder. All
the vc1_decoder object files were included in the vc1_parser line
in libavcodec/Makefile before, but architecture specific object files
for vc1_decoder were not.

6039248018 mem: fix pointer pointer aliasing violations
This uses explicit memory copying to read and write pointer to pointers
of arbitrary object types. This works provided that the architecture
uses the same representation for all pointer types (the previous code
made that assumption already anyway).

3c18a7b188 avio: Do not consider the end-of-buffer position valid
Trigger a refill if the seek action moves the pointer
at the end of the buffer.

Before this patch the read action following the seek would trigger
the refill, while write action would write outside the buffer.

In the Libav codebase few muxers seek forward outside of what
already has been written so it is quite unlikely to experience
the problem with the default buffer size.

167e004e1a h264: drop any pretense of support for data partitioning
It does not work correctly and apparently never did. There is no
indication that this (mis)feature is ever used in the wild or even that
any software other than the reference supports it.

Since the code that attempts to support it adds some nontrivial
complexity and has resulted in several bugs in the past, it is better to
just drop it.

cf1e0786ed error_resilience: move the MECmpContext initialization into ER code
Currently, it needs to be initialized by the ER caller (which is
currently either a mpegvideo decoder or h264dec). However, since none of
those decoders use MECmpContext for anything except ER, it makes more
sense to handle it purely inside ER.

2a06c2a03e mpegvideo_enc: Draw edges on input for non-multiple of 16 resolutions
This improves motion estimation and avoids using uninitialized data
for resolutions that aren't a multiple of 16.

Prior to d2a25c40, the edges used to be initialized so that encoding
was deterministic, but after that commit it started using uninitialized
data (for non multiple of 16 resolutions).
