Make the malloc(3) family of functions weak and make their non-weak

implementations visible for use by applications. The functions $F that
are now weak symbols are:
	allocm, calloc, dallocm, free, malloc, malloc_usable_size,
	nallocm, posix_memalign, rallocm, realloc, sallocm

The non-weak implementations of $F are exported as __$F.
