libs have it, it is a function that is considered harmful, so:
Delete malloc_usable_size(). It is a function that blurs the line
between malloc managed memory and application managed memory and
exposes some of the internal workings of malloc. If an application
relies on that, it is likely to break using another implementation
of malloc. If you want usable size x, just allocate x bytes. ok

here could creates non-uniformity since very short fetches of 0 would
be excluded. blocks of 0 are just as random as any other data, including
blocks of 4 4 4.. This is a misguided attempt to identify errors from the
entropy churn/gather code doesn't make sense, errors don't happen.

The C implementation of str{,r}chr are not linked to the build, because
assembly implementations are used, but change to code for easier reference.
At least the i386 and amd64 are checked and seem to do the correct thing.
Found thanks to the csh any/strchr change.
minor pointers and OK millert@
- Start with a full page of struct region_info's
- Save an mprotect in the init code: allocate 3 pages with none and
make the middle page r/w instead of a r/w allocation and two calls to make the
guard pages none
but at that time ffs function calls were generated instead of the
compiler inlining the code. Now that ffs is marked protected in
libc this is handled better. Thanks to kshe who prompted me to
look at this again.
dance, mark it protected. This works better for both gcc and clang: gcc
blocks overriding of internal calls, while clang permits inlining again.

to builtins like mem{set,cpy,move} and __stack_smash_handler. So, when
building with clang, instead mark those as protected visibility to get rid
of the PLT relocations. We can't take the address of them then, but that's
ok: it's a build-time error not a run-time error.
ok kettenis@
Complete in the sense that all POSIX *locale(3) and *_l(3) functions
are included, but in OpenBSD, we of course only really care about
LC_CTYPE and we only support ASCII and UTF-8.
With important help from kettenis@, guenther@, and jca@.
Repeated testing in ports bulk builds by naddy@.
Additional testing by jca@, sebastia@, dcoppa@, and others.
OK kettenis@ dcoppa@, and guenther@ on an earlier version.
Riding guenther@'s libc/librthread major bump.
