  avutil: Remove deprecated intfloat_readwrite code

Conflicts:
	libavutil/intfloat_readwrite.c
	libavutil/intfloat_readwrite.h

The files are left in place as they are still used by some projects
mplayer is one.
Theres no hurry in removing the code, it can as well be removed once
no projects use it anymore
