a22ae9f0c5 mpegts: Remove one 64-bit integer modulus operation per packet
The common case of the pointer having increased by one packet (which results
in no change to the modulus) can be detected with a 64-bit subtraction,
which is far cheaper than a division on many platforms.

d7a4f8f8b9 Move MASK_ABS macro to libavcodec/mathops.h
This macro is only used in two places, both in libavcodec, so this
is a more sensible place for it.

Two small tweaks to the macro are made:

- removing the trailing semicolon
- dropping unnecessary 'volatile' from the x86 asm
