Use alloc_size attribute on *alloc functions

malloc and family were not declared with __attribute__((alloc_size)).
This was (sometimes) preventing FORTIFY_SOURCE related functions
from knowing the size of the buffer it's dealing with, inhibiting
FORTIFY_SOURCE protections.

Add __attribute__((alloc_size))

Information about the alloc_size attribute can be found
at http://gcc.gnu.org/onlinedocs/gcc/Function-Attributes.html
