It's been a quarter century: we can assume volatile is present with that name.

Switch libc and libm to use strong aliases rather than weak aliases
where appropriate. Among other things makes the symbols consistent

While at it, kill unused LINTLIBRARY/PROTOLIB1 cruft which was there
to trick lint into recording the right prototypes for aliased
functions. Most of the work done at the awesome n2k13 hackathon.

Agreed by kettenis@, guenther@, matthew@.

Remove excessive sys/cdefs.h inclusion
ok guenther millert kettenis

Revert (leaving the complex math part alone). Some stuff is depending
on this historical behavior; so we're stuck in this stupid situation.
No cookie for me.

this is not a write-only register. might have caused to optimize
it away. ok miod@

since there's nothing else in arm's fabs.c, replace

Credits to drahn@ otto@ and deraadt@ for feedback and help testing.

Upgrade procedure if you don't want to use the damn snapshots:
- build and install new kernel, reboot off it
- build new gcc, do not install it yet
- make includes
- install new gcc
- build and install lib/csu and lib/libc
- make build

Move (back) to softfloat on sh for now.

Preliminary userland bits for OpenBSD/landisk, many things coming from
NetBSD.
