a4d179eeb6 Document memset_s(3). memset_s(3) is defined in
C11 standard (ISO/IEC 9899:2011) K.3.7.4.1 The memset_s function
(p: 621-622)

Fix memset(3) portion of the man page by replacing the first argument
(destination) "b" with "dest", which is more descriptive than "b".
This also makes it consistent with the term used in the memset_s()
portion of the man page.

See also http://en.cppreference.com/w/c/string/byte/memset.

9851b3400a Implement the memset_s(3) function as specified by the C11 ISO/IEC
9899:2011 Appendix K 3.7.4.1.

Other needed supporting types, defines and constraint_handler
infrastructure is added as specified in the C11 spec.

d0fd0203fb Replace dot-dot relative pathing with SRCTOP-relative paths where possible
This reduces build output, need for recalculating paths, and makes it clearer
which paths are relative to what areas in the source tree. The change in
performance over a locally mounted UFS filesystem was negligible in my testing,
but this may more positively impact other filesystems like NFS.

LIBC_SRCTOP was left alone so Juniper (and other users) can continue to
manipulate lib/libc/Makefile (and other Makefile.inc's under lib/libc) as
include Makefiles with custom options.

8876613dc5 Replace use of ${.CURDIR} by ${LIBC_SRCTOP} and define ${LIBC_SRCTOP}
if not already defined. This allows building libc from outside of
lib/libc using a reach-over makefile.

A typical use-case is to build a standard ILP32 version and a COMPAT32
version in a single iteration by building the COMPAT32 version using a
reach-over makefile.

46632c18bd Merge index() and strchr() together.
As I looked through the C library, I noticed the FreeBSD MIPS port has a
hand-written version of index(). This is nice, if it weren't for the
fact that most applications call strchr() instead.

Also, on the other architectures index() and strchr() are identical,
meaning we have two identical pieces of code in the C library and
statically linked applications.

Solve this by naming the actual file strchr.[cS] and let it use
__strong_reference()/STRONG_ALIAS() to provide the index() routine. Do
the same for rindex()/strrchr().

This seems to make the C libraries and static binaries slightly smaller,
but this reduction in size seems negligible.

2c0959ae6b Powerpc is special here. powerpc and powerpc64 use different ABIs, so
their implementations aren't in the same files.  Introduce LIBC_ARCH
and use that in preference to MACHINE_CPUARCH.  Tested by amd64 and
powerpc64 builds (thanks nathanw@)

ae80efa54f Handle machine-dependent (m-d) (string) sources more automatically.
The names of m-d variants are now added (manually) to MDSRCS instead
of to SRCS, and the names of all machine-independent (m-i) variants
that can reasonably be replaced by an m-d variant are now added
(manually) to MISRCS instead of to SRCS, so that a simple substitution
can be used to discard the unused m-i variants.  MISRCS is potentially
all m-i sources, but the substitution is too simple to be fast, so
MISRCS should be kept reasonably small.

libc/Makefile.inc:
Do the substitution.

libc/i386/string/Makefile.inc:
Add to MDSRCS instead of to SRCS.  Add the names of all sources in this
directory, but no others.

libc/string/Makefile.inc
