f1e173049e avcodec/jpeg2000: Remove CBLK limit 
This also reduces the amount of memory needed
Fixes Ticket4672

The new code seems slightly faster as well, probably due to better cache usage

8bedbb82ce j2k/jpeg2000: split data pointer in int & float. 
This fixes a TODO item and unifies both decoders structures
It also fixes undefined behavior due to aliasing violations

I choose 2 fields instead of a union because mistakely using the
wrong type with a union will lead to hard to debug "wrong output"
while with 2 fields mistakely using the wrong type will crash
with a null pointer derefernce which is much easier to debug
