THREAD_UNLOCK() on error before returning; millert@ ok.

correct an alignment mis-conception for malloc(0) returned regions.
OK deraadt@

mprotect allocations sized at 0 bytes. This will cause a fault for access
to such, permitting them to be discovered, instead of exploited as the ssh

-1 -> MAP_FAILED

Use madvise(MADV_FREE) to allow the 'h' option.
(the code was already there, just not enabled).

calloc() needs to be separate from malloc in case a user wants to have
their own malloc() implementation.

Move calloc() into malloc.c and only zero out the area if malloc()
didn't do so for us. By default, malloc() zeros out the space it
allocates but the programmer cannot rely on this as it is implemen

Move calloc() into malloc.c and only zero out the area if malloc()
didn't do so for us. By default, malloc() zeros out the space it
allocates but the programmer cannot rely on this as it is implementation-
specific (and configurable via /etc/malloc.conf)

use writev() where possible

wrong ret type for write define (millert@)

malloc can't use write() if it fails very early, so use the unwrapped syscall _thread_sys_write() if we are threaded

Add thread-safety to libc, so that libc_r will build (on i386 at least).

(setlogin is no longer a special syscall)
Add -pthread option to gcc (that makes it use -lc_r and -D_POSIX_THREADS).
Doc some re-entrant routines
Add libc_r to intro(3)
dig() uses some libc srcs and an extra -I was needed there.
Add more md stuff to libc_r.
Update includes for the pthreads api

Don't enumerate every arch in the #if since all OpenBSD platforms use the same values for malloc_pageshift and malloc_minsize except for sparc

Oh fun, mucking about with files used on all archs.

This is one of many places in the source that have

Is there some possible way to eliminate, reduce these or

Oh fun, mucking about with files used on all archs.

This is one of many places in the source that have
#if defined("list all architectures")
Is there some possible way to eliminate, reduce these or at least
have a file that describes all occurrances so that when a new port is
done this could be addressed. like the recent hppa port, does it need to
take a look at this????

Change realloc(foo,0) to behave like malloc(0). Both now return a pointer
to an object of size zero. This will allow testing on reallocs return value
to determine if the operation was successful or n

malloc_init() should try to not modify errno

Use MALLOC_EXTRA_SANITY consistently (EXTRA_SANITY was used in many places)
sizeof *pt -> sizeof *px (point to same type of struct but looked wrong).

Make it possible to not output warnings (errors causing aborts are always
output).

Add x/X option to behave like X11 xmalloc; from FreeBSD
Reduce diffs wrt. FreeBSD some

Be more careful with mixing types

Check for overflow; from FreeBSD
