e268a352af mjpegdec: parse RSTn to prevent skipping other data in mjpeg_decode_scan 
Check explicitly if enough bits are left to prevent an infinite loop
when the bitstream buffer is not followed by zero-padding.

Based on patches by Michael Niedermayer <michaelni@gmx.at>.

4b84f68223 4xm: pass the correct remaining buffer size to decode_i2_frame(). 
frame_size is the number of bytes left in the packet, so if we are passing
buf-4 we can safely read frame_size+4 bytes.

a2d1d21629 avio: exit early in fill_buffer without read_packet 
Fixes an invalid free() with ass in avi. The sample in bug 98 passes
parts of AVPacket.data as buffer for the AVIOContext. Since the packet
is quite large fill_buffer tries to reallocate the buffer before doing
nothing. Fixes bug 98.

d209c27b09 vc1dec: fix invalid memory access for small video dimensions 
For small video dimensions, these calculations of the upper bound
for pixel access may have a negative result. Using an unsigned
comparison to bound a potentially negative value only works if
the greater operand is non-negative. Fixed by doing edge emulation
when the upper bound is probably negative, everywhere that this
pattern appears.

For small video dimensions calculations of the upper bound for pixel

works only if the greater operand is non-negative. This is fixed by
doing edge emulation explicitly for such conditions.

98f24ecd6c rv34: joint coefficient decoding and dequantization 
Perform dequantization while decoding coefficients instead of performing it
on the entire coefficients buffer.

Since quantized coefficients are very sparse, this usually causes a small
speedup. Speedup of around 1% on Panda board compared to the removed here
neon code. Global speedup is probably around 3%.

0749720b6c avplay: Don't call avio_set_interrupt_cb(NULL) 
Since we don't use avio_set_interrupt_cb for interrupt callbacks,
we don't need to call it to reset the interrupt cb either.

This avoids a warning about use of deprecated functions.
