Only include <assert.h> and <string.h> if !_KERNEL && !_STANDALONE

Actually... We need libkern.h also under _STANDALONE, so that
_DIAGASSERT gets defined. Fixes the mvmeppc libsa build.

- remove bcmp(9), bcopy(9), and bzero(9) from libkern since <sys/systm.h> has
macro which replace them with mem*() functions in #ifdef _KERNEL as noted
in man pages
- move declarations of bcopy(3) and bzero(3) into <lib/libsa/stand.h>
since they are still in libsa for some MD standalone sources
(I guess all bcmp(3) in standalone sources have been replaced with memcmp(3)
but they should be replaced with memcmp() anyway)

Add local declarations of bcmp() and bzero() because libkern.h no longer
provides those declarations.

It's possible that these can be removed later when we find out whether
these functions are actually needed in the kernel, but meanwhile, this
allows alpha, hp700 and the powerpc ports (who all build these as part
of libkern) to complete their builds.

for that. This way we pass the lib/libc/string/strrchr regression tests.

Merge libkern + libc common files. As requested by core.

branches: 1.3.78;
handle fortify, ansify.

don't do the weak symbol thing in kernel context.

branches: 1.1.2; 1.1.4;
Add strsep(3) to libkern.

To avoid code duplication, move strsep.c to the kernel/userland
common files.

Soon I will commit source-address selection (options IPSELSRC).
It will use strsep(3).

strspn: fix typo in comment

branches: 1.2.4;
fixes for GCC 6:

- -Wstrict-prototypes is not available for C++, so don't try to
ignore it for C++.
- remove many _DIAGASSERT() checks against not NULL for functions
with arguments with nonnull attributes. in two cases, leave
code behind that should set defaults to "(null)".
- use -Wno-error=frame-address for i386 mcount, as it seems valid
to assume the caller will have a frame.fair

branches: 1.1.2; 1.1.6;
