src/libexec/rtld-elf/malloc.c, branch releng/8.1

In preparation for a new malloc implementation:

2006-01-12T07:28:21Z

* Add posix_memalign(). * Move calloc() from calloc.c to malloc.c. Add a calloc() implementation in rtld-elf in order to make the loader happy (even though calloc() isn't used in rtld-elf). * Add _malloc_prefork() and _malloc_postfork(), and use them instead of directly manipulating __malloc_lock. Approved by: phk, markm (mentor)

Very minor style nit: sort include files alphabetically.

Fix signed/unsigned comparison warnings.

2003-05-04T00:56:00Z

Add missing include files I forgot about in previous commit.

Remove /usr/lib/elf from a default search path.

Move xprintf to malloc.c, it is only used there. Make static. Submitted by: phantom

Include stddef.h for NULL definition, rather than rolling our own here.

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

2002-01-24T12:11:31Z

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.
