66f5a6b419 mpegvideo: drop 'inline' from some functions
These functions do not benefit from being inlined.  They are large,
and there are no opportunities for constant propagation.

66f52d0c3d nellymoserdec: drop support for s16 output.
It internally decodes as float and then converts to s16 by a call to
float_to_int16(). The caller can do this just as well by using lavr.

8b78c2969a bmpdec: only initialize palette for pal8.
Gray8 is not considered to be paletted, so this would cause an invalid
write.

Fixes bug 367.

3b4bb19e63 lavf: flush the output AVIOContext in av_write_trailer().
This is consistent with stdio and is what we want to do in all cases.

Fixes a bug in the voc muxer which didn't flush in write_trailer()
previously. This is the cause of the change in the test results.

692dd8ed26 configure: x86: improve ebp availability check
Some compilers are extra strict about register usage in main(),
disallowing ebp in inline asm there while allowing it elsewhere.
This change makes the test better reflect actual usage.

714508bcb9 vorbisdec: ensure FASTDIV denominator is never 1
In both usages of FASTDIV the denominator might be 1.

Using a branch could make the function slower than using a normal
division.

Both denominator and numerator can be multiplied by 2 safely and
using shifts is faster than using a branch.

62c9ae11a7 Add a smooth streaming segmenter muxer
This muxer splits the output from the ismv muxer into individual
files, in realtime.

The same can also be done by the standalone tool ismindex, but this
muxer is needed for doing it in realtime (especially for live
streams that need extra handling for updating the lookahead fields
in the fragment headers).

Using this muxer, one can deliver live smooth streaming from a
normal static file web server. (Using ismindex, one can deliver
premade smooth streaming files from a static file web server,
or prepare files for serving with IIS.)
