Change brk's prototype from char *brk(const char *) to int brk(const void *)

and sbrk's prototype from char *sbrk(int) to void *sbrk(intptr_t).

This makes us more consistant with NetBSD and standards which include
these functions. Bruce pointed out that ptrdiff_t would probably
have been better than intptr_t, but this doesn't match other
implimentations.

Also remove local declarations of sbrk and unnecessary casting.
