The alignment guaranteed by malloc is not always sufficient. E.g. vector
instructions or hardware subsystems want specifically aligned buffers. The
attached patch will use posix_memalign if available to allocate buffers.
Alignment is pagesize().

We could have a configure option to specify the alignment needs.

Elements would still need to check the alignment and do a memcopy if the
alignment is not good. E.g. we cannot guarantee alignments when doing
subbuffers.
