Redo l10n support in the strerror family.

Instead of opening the message catelog whenever strerror is called,
keep track of the translations in the locale cache. For the C locale,
the builtin sys_errlist is used directly. Other locales will open
the catalog file on the first strerror call and build a translation
table, so that further calls in this locale can just use an array
lookup.

Install strncpy.3 to fix build

strncpy(3), stpncpy(3): Split man page out of strcpy(3), stpcpy(3).

These are for substantively different purposes (fixed-width fields
with optional NUL padding vs NUL-terminated strings), so they don't
belong together.

for GCC, built memset.c with -fno-builtin. this avoids GCC 10 compiling
memset() and emitting calls to memset() where it seems code that looks
like what memset() does, which ends up recursing and blowing the stack.

this makes mips userland with GCC 10 work.

Document strerror_l()

While here also document (but comment it out since it isn't
available - yet) strerror_lr(). To include that, simply
uncomment the relevant lines, and (twice I think) s/returns/return/
on lines just after currently commented out lines (that is, it
currently says, "A returns" after the comments are returned, we
need it to be "A and B return" - the "and B" appears when the comment
markers are removed, removing the 's' from returns must be done manually.

In addition to adding strerror_l() some additional enhancements were
made to the general strerror() doc.

Import wcsnlen(3) to libc

The wcsnlen(3) function conforms to POSIX.1-2008 and is an addition to the
ISO C standard.

size_t wcsnlen(const wchar_t *s, size_t maxlen);

The wcsnlen(3) function computes the number of wide-characters in a wide-
-string to which s points, not including NULL terminating wide-character
code and checking no more than maxlen wide-characters. This function never
examines wide-characters beyond a wide-string of maxlen size.


This function is a safer version of wcslen(3):

size_t wcslen(const wchar_t *s);


Update STANDARDS section of wmemchr(3) describing wide-character functions.

Replace consttime_bcmp/explicit_bzero by consttime_memequal/explicit_memset.

consttime_memequal is the same as the old consttime_bcmp.
explicit_memset is to memset as explicit_bzero was to bcmp.

Passes amd64 release and i386/ALL, but I'm sure I missed some spots,
so please let me know.

Add consttime_bcmp(3) and explicit_bzero(3) to makefile and set lists.

branches: 1.76.2;
Add "consttime_bcmp" and "explicit_bzero" functions for both kernel
abd userland, as proposed on tech-security, with explicit_bzero using
a volatile function pointer as suggested by Alan Barrett.
Both do what the name says. For userland, both are prefixed by "__"
to keep them out of the user namespace.

sense -- these are just some examples, more to come.

If SRCS contains any .S files then remove the corresponding .c file from

files for all the files they don't override.

Move popcount et al to src/common and add popcount32/popcount64.
Requested by rmind@. MD should now override popcount32/popcount64 and

Add popcount(3) and the long and long long version. Name is inspired by
gnulib, the implementation goes back to the AMD Software Optimizer
guide. A number of platforms will want to replace the C version with

[libc]
- localeio.[ch] and lc*.[ch] in src/lib/libc/locale was replaced by
new locale-db implementation using citrus_db backend,
see src/lib/libc/citrus/citrus_lc_*.[ch].
- add citrus_bcs_strtou?l.c. don't use strtou?l locale implementation
internally, because they're locale-aware function.
- add some stubs for multi-locale issue, see {current,global}_locale.c.
- remove some obsolete file, setrunelocale.c, ___runetype_mb.c.
- remove __savectype() from ctypeio.[ch].

[tools]
- mklocale(1): add new option ``-t'' that generates new style
LC_{MONETARY,NUMERIC,TIME,MESSAGES} locale-db format.
- chrtbl(1): added ctypeio.[ch] for __savectype().

[locale-db]
- added en_US.US-ASCII locale.
- removed some shareable locale definition file:
en_US.US-ASCII -> en_US.ISO8859-1, en_US.UTF-8
zh_CN.eucCN -> zh_CN.GB18030
and more...see src/share/locale/*/Makefile.
- remove obsoleted locale sr_YU, added new locale sr_ME, sr_RS.
- change locale name ja_JP.ISO2022-JP* -> ja_JP.ISO-2022-JP*
for X11's locale.alias file alignments.
- fix regression test, wrong wcs?width(3), NAN/INF usage.

i tested release-build following arch:
i386, amd64, hpc{mips,arm,sh}, sparc64, vax.

citrus_lc_*.[ch] also can read old-plain-text style locale-db.
so that backward compatibility is keeped, but lc*.[ch] can't read
new citrus_db'ed locale-db and localeio.c never check sanity,
so forward compatibility is broken ;-<

Delete unnecessary definitions of SIGRTMIN & SIGRTMAX

Long ago, SIGRTMIN & SIGRTMAX were #ifdef _KERNEL in

here (#ifndef SIGRTMIN so the duplicates vanished for
all practical purposes in 2016 when the symbols were
exposed to userland).

KNF. NFC.

Stop attempting to return a (char*) in place of (const char *)

This removes a cast that was added in 1994, when __strsignal()
returned a char * to convert the const char * element of sys_siglist
into a type that matched.

It should have been removed when __strsignal() was changed to
return const char * in 1998. But wasn't.

This should fix an inane warning (treated as an error) from a
compile stupid enough to allow a natural char * (as in char buf[N])
to be returned as a result (which is, of course, fine), but complains
about returning (char *) applied to a (const char *).

If port provides __weak_alias(), provide an Standard C and POSIX pure
identifier namespace by renaming non standard functions and variables
such that they have a leading underscore. The library will use those
names internally. Weak aliases are used to provide the original names
to the API.

This is only the first part of this change. It is most of the functions
which are implemented in C for all NetBSD ports. Subsequent changes are
to add the same support to the remaining C files, to assembly files, and
to the automagically generated assembly source used for system calls.
When all of the above is done, ports with weak alias support should add
a definition for __weak_alias to <sys/cdefs.h>.

Use reach-over sources from common/lib/libc

fix warns=4

Move UCB-licensed code from 4-clause to 3-clause licence.

Patches provided by Joel Baker in PR 22280, verified by myself.

back out the #ifdef _DIAGNOSTIC argument checks; too many people complained.
_DIAGASSERT() is still retained.

* use _DIAGASSERT() to check pointer arguments against NULL and file
descriptors against -1 (as appropriate).
* add actual checks which to detect stuff that would trigger_DIAGASSERT(),
and attempt to return a sane error condition.
* knf some code
* remove some `register' decls.

the first two items result in the addition of code similar to the
following in various functions:

_DIAGASSERT(path != NULL)
#ifdef _DIAGNOSTIC
if (path == NULL) {
errno = EFAULT;
return (-1);
}
#endif

when deciding whether to use standard system include files or libkern.h,
check _STANDALONE as well as _KERNEL. _KERNEL is incorrect for use when
building boot blocks, and it looks like the rest of the code is already
using _STANDALONE for this purpose.

remove obsolete register declarations

update to lite-2

add appropriate #ifdefs (kernel includes) so that these files can
be copied to libkern and built without modification.

Fix RCSID's
Use "extern.h" where appropriate.

don't include <sys/cdefs.h>, it's a 'private' header

Declare rcsid strings so they are stored in text segment.

Replace consttime_bcmp/explicit_bzero by consttime_memequal/explicit_memset.

consttime_memequal is the same as the old consttime_bcmp.
explicit_memset is to memset as explicit_bzero was to bcmp.

Passes amd64 release and i386/ALL, but I'm sure I missed some spots,
so please let me know.

Add man pages and xrefs for consttime_bcmp and explicit_bzero.

Use reach-over sources from common/lib/libc

Replace complicated and ugly makefile gook to make memmove,memcpy by
-Ding the bcopy.c source (and similarly strchr from index.c, strrchr
from rindex.c) with stub .c files for memmove, memcpy, strchr and
strrchr that simply #define the appropriate thing and #include the
appropriate .c file. Inspired by the way many m-d .S files handle the
same thing. This radically simplifies the Makefile.inc for libc/string
(and libkern).
