295a7c0238 4xm: Prevent buffer overreads. 
4xm decoder while decoding i2 frames can overread the buffer if proper checks
are not made.

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.

893f137679 4xm: fix calculation of the next output line position in decode_i2_frame(). 
The current code doesn't work unless width is an exact multiple of 16.

00a1cdd264 Place some START_TIMER invocations in separate blocks. 
This fixes compilation failures related to START_TIMER/STOP_TIMER macros and
-Werror=declaration-after-statement.  START_TIMER declares variables and thus
may not be placed after statements outside of a new block.

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.

aacf6b3a2f rv34: fix invalid memory access for small video dimensions 
For small video dimensions calculations of the upper bound for pixel
access may result in negative value. Using an unsigned comparison
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.
