1bb07edbd4 Fix strcasecmp_l() and strncasecmp_l() POSIX 2008 compliance.
POSIX.1-2008 specifies that those two functions should be declared by
including <strings.h>, not <string.h> (the latter only has strcoll_l()
and strxfrm_l()):

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.

bar on understanding, so that programmers/auditors will a better job calling
all 3 of these functions."

e73151eb82 libc: Always use our own copy of sys_errlist and sys_nerr (.so only).
This ensures strerror() and friends continue to work correctly even if a
(non-PIE) executable linked against an older libc imports sys_errlist (which
causes sys_errlist to refer to the executable's copy with a size fixed when
that executable was linked).

The executable's use of sys_errlist remains broken because it uses the
current value of sys_nerr and may access past the bounds of the array.

Different from the message "Using sys_errlist from executables is not
ABI-stable" on freebsd-arch, this change does not affect the static library.
There seems no reason to prevent overriding the error messages in the static
library.

19c262fe87 Change index() and rindex() to a weak alias.
This allows people to still write statically linked applications that
call strchr() or strrchr() and have a local variable or function called
index.

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.

3c87aa1d3d Implement xlocale APIs from Darwin, mainly for use by libc++. This adds a
load of _l suffixed versions of various standard library functions that use
the global locale, making them take an explicit locale parameter.  Also
adds support for per-thread locales.  This work was funded by the FreeBSD
Foundation.

Please test any code you have that uses the C standard locale functions!

2973057493 Allow strerror(0) and strerror_r(0, ...).
Of course, strerror_r() may still fail with ERANGE.

Although the POSIX specification said this could fail with EINVAL and
doing this likely indicates invalid use of errno, most other
implementations permitted it, various POSIX testsuites require it to
work (matching the older sys_errlist array) and apparently some
applications depend on it.

dabae22639 Two optimizations to MI strlen(3) inspired by David S. Miller's
blog posting [1].

 - Use word-sized test for unaligned pointer before working
   the hard way.

   Memory page boundary is always integral multiple of a word
   alignment boundary.  Therefore, if we can access memory
   referenced by pointer p, then (p & ~word mask) must be also
   accessible.

 - Better utilization of multi-issue processor's ability of
   concurrency.

   The previous implementation utilized a formular that must be
   executed sequentially.  However, the ~, & and - operations can
   actually be caculated at the same time when the operand were
   different and unrelated.

   The original Hacker's Delight formular also offered consistent
   performance regardless whether the input would contain
   characters with their highest-bit set, as it catches real
   nul characters only.

These two optimizations has shown further improvements over the
previous implementation on microbenchmarks on i386 and amd64 CPU
including Pentium 4, Core Duo 2 and i7.
