_C_LABEL() and _ASM_LABEL() are no longer useful in the "everything
is ELF" world. Eliminate use of them in amd64, arm64, armv7, i386,
macppc, mips64, and sparc64 code.

Remove long unused WARN_REFERENCES macro; idea guenther@, ok jsg@ jca@

Provide ENTRY_NB() for i386

ok guenther

More steps for i386 Meltdown fix:

- provide struct cpu_info_full
- prepare K-U sections
- reorganize interrupt, trap, syscall entry to use K-U trampoline
- prepare pmap for entering special mappings, the mappings are not
setup yet

This code will already trigger performance issues. We do more tlb
flushes, but we do not unmap the kernel yet. The latter
will be needed to prevent Meltdown.

kill RCSID macros; discussed with millert

Provide remaining arch with END() macro for setting calculated size on
symbols in ASM

ok deraadt@ mpi@

Add STRONG_ALIAS macros to be used from assembly code in libc and
libm. While at it, remove now unused workarounds for lint.
Agreed by kettenis@, guenther@, matthew@.

Convert cpp | as rules in bsd.lib.mk and lib/libc/sys/Makefile.inc to pure cc
invocations. This allows us to use the compiler builtin define __PIC__ to check
for PIC/PIEness rather than passing -DPIC. Simplifies PIE work a lot.

ok matthew@, conceptually ok kurt@

Normalize sentinel. Use _MACHINE_*_H_ and _<ARCH>_*_H_ properly and consitently.

Discussed and okay drahn@. Okay deraadt@.

We can now access curcpu() members through %fs instead of doing it
with the complicated and expensive macros.
