Inconsistencies between the dimensions/pixel format of avctx and the
frame can confuse API users.
For example this can crash the demuxing_decoding example.
Back up the previous values and restore them, when decoding the next
frame. This is necessary, because these can be different between the
returned frame and the last decoded frame.

Fixes clang warning "absolute value function 'fabsf' given an argument
of type 'double' but has parameter of type 'float' which may cause
truncation of value [-Wabsolute-value]".
Having this macro in an header only facilitates the use of such header.
The code increase is minimal and files have one less dependency
on mpegvideo.h.
These 2 are highly related so they are in the same commit
Fixes part of Ticket4605
Fixes p0_04.j2k

This is implemented but i suspect does not work correctly as no file using this
seems to decode correctly.

This works with one of 2 RLCP samples i have, the other appears to also
use selective arithemtic coding bypass which may or may not be the reason why it does
not work
