10b77fbf0d avcodec/mips: Split uni mc optimizations to new file
This patch moves HEVC code of uni mc cases to new file hevc_mc_uni_msa.c.
(There are total 5 sub-modules of HEVC mc functions, if we add all these modules in one single file, its size would be huge (~750k) & difficult to maintain, so splitting it in multiple files)
This patch also adds new HEVC header file libavcodec/mips/hevc_macros_msa.h

0ad04bf6a2 dvdsubdec: reset buffer size on invalid over-large packets
Otherwise it will never be reset, and remain "stuck" in this state
forever. Can happen when seeking: the decoder will receive fragments
from different file positions, which triggers the condition easily.

9ae766d1c6 avcodec/vdpau: Re-factor pre-hwaccel helper functions into separate header
h264.h and hevc.h are mutually exclusive due to defining some of the same
names. As such, we need to avoid forcing h264.h to be included if we want
hevc decode acceleration to be possible.

However, some of the pre-hwaccel helper functions need h264.h. To avoid
messy collisions, let's move the declaration of all those helpers to
a separate header which we will exclude for the hevc support (which will
be hwaccel-only).

e48a9ac9af libshine: fix support for shine 3.0
shine_encode_buffer expects written to be an int pointer, while the
previous shine_encode_frame expected it to be a long pointer.

Thus encoding with libshine currently always fails with
"internal buffer too small", because a negative return value of
shine_encode_buffer is interpreted as a very large long value.
