Michael Niedermayer dfa5d1a366 avcodec/iff: Check for overlap in cmap_read_palette()

Andreas Rheinhardt f12e662a3d libavcodec/iff: Use unsigned to avoid undefined behaviour 
The initialization of the uint32_t plane32_lut matrix uses left shifts
of the form 1 << plane; plane can be as big as 31 which means that this
is undefined behaviour as 1 will be simply an int. So make it unsigned
to avoid this.

Michael Niedermayer f76d7352e0 avcodec/iff: Check ham vs bpp 
This checks the ham value much stricter and avoids hitting cases which cannot be reached
with data from the libavformat demuxer.
