avcodec/utils: initialize pixel buffer pool
This should silence many valgrind warnings about use of uninitialized data, all the warnings i looked at where false positives having their uninitialized data not actually used. The same effect could be achieved by listing all code that touches the pixel buffer in the valgrind suppression file. Note, valgrind also fails to trace the origins correctly.
