Blackfin arch: fix some bugs in lib/string.h functions found by our string testing modules
- use ints for the return value rather than char since we actually return
an int and we dont want it improperly being sign extended during the reload
http://blackfin.uclinux.org/gf/project/uclinux-dist/tracker/?action=TrackerItemEdit&tracker_item_id=3525
- if src is shorter than the requested number of copy bytes, we need to null
pad the rest
http://blackfin.uclinux.org/gf/project/uclinux-dist/tracker/?action=TrackerItemEdit&tracker_item_id=3524
- mark these as __volatile__ and add memory to the clobber list so gcc does
not optimize buffers around on us we may be using
- rewrite asm code to be readable/maintainable
