Use the same inline assembly constraints as for libc fp*(), when operating
on the floating-point control register.

Reduce libm's exports and make internal calls go direct.
All dependencies on libc are now via reserved/standardized names.

Missing $OpenBSD$'s.

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

Switch libc and libm to use strong aliases rather than weak aliases
where appropriate. Among other things makes the symbols consistent
across all architectures (notably where ldbl mantissa is 53 bits).

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@.

Aliases for extended precision were missed on a few functions on hppa.
Reported by Brad, thanks!

Tweak inline asm to prevent gcc4 from optimizing away crucial bits of it.

(the 33,000 line diff is essentially mechanical)
ok with the idea millert, ok dms
