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.

Be more specific about the security issues.

Add companion mempcpy to wmempcpy, bump.

new gdb needs wmempcpy, give it to it.

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.

[libc]
- localeio.[ch] and lc*.[ch] in src/lib/libc/locale was replaced by
new locale-db implementation using citrus_db backend,

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.

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.

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 ;-<

old mklocale(1) doesn't know -t option, so you have to rebuild toolchain.

Add strings(3), collecting information about strings.h.
Add Xr for it to string(3).

XXX: if someone could make a HISTORY section, I'd appreciate it

PR/34238: Aleksey Cheusov: add wcsdup, wcscasecmp and wcsncasecmp functions

- Add strndup and stresep
- Use stresep so in fstab so that we can mount paths with white space in them.

branches: 1.60.2;
fix lib/33476:
added following manpages (derived from FreeBSD),
wcwidth(3) wcswidth(3)
wcstol(3) wcstoll(3) wcstoimax(3)
wcstoul(3) wcstoull(3) wcstoumax(3)
and update doc/TODO.i18n.

Use reach-over sources from common/lib/libc

- Fix the remaining indr_references so that they define lint symbols.
- Add an internal symbol for strerror_r (thanks klaus for noticing)
- Remove internal __strerror

PR/30845: Luke Mewburn: strerror_r(3) missing
- Merge 4.4BSD strerror.3 man page changes that summarize information
for all the error printing functions. This makes the perror(3) page
obsolete.
- Implement all error functions in terms of strerror_r(), including
__strerror() which is not used internally. Can it be removed?
- Bump version for strerror_r

Fix stupid typo. I added memmem, not memmove.

add memmem

Add strcasestr(3), case insensitive version of strstr(3).
Bump libc minor.

From FreeBSD.

- add wcstok(3),
- move btowc() and wctob() into each ctype modules,
- bump ctype interface ABI version,
- bump i18n modules' minor and
- update sets.
and fix a stupid bug in _RUNE_ISCACHED macro.

Need internal names for strlcat() and strlcpy().

split wide char section, just for readability/future possibility for .if

move wcs* and wmem* from lib/libc/locale to lib/libc/string.

update for knf (return value on separate line to function name...)
check dst and src aren't null pointers before trying to use them
enable strlcat/strlcpy

use ${ARCHDIR} instead of ${.CURDIR}/arch/${MACHINE_ARCH} where appropriate
libc builds on pmax again

Install a link for strtok_r(3).

switch bzero to version in memset.c.
bzero.c is now a "#define BZERO//#include memset.c" type file.
Remove comment from Makefile about the fact that this is on the todo list.

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).

note that bzero isn't yet being built from memset.c

update to lite-2

Update various aspects of the special target builds which should
have been done (by others) a long time ago:
* fix PIC compilation to use new PIC flags,
* make them 'make -j N' safe.

- use CPPFLAGS instead of CFLAGS
- use ${COMPILE.C} ... instead of ${CC} ${CFLAGS} -c ...

branches: 1.40.2;
rcsid police

move str[fp]time into libc/time.

add rules to build .ln files (memmove.ln, memcpy.ln, strchr.ln, strrchr.ln)
for objects built specially from other C files, when appropriate.

Add strtok_r() for reentrant (thread-aware) programs

Make it possible to have a md version of memccpy.

Clarify a comment slightly.

Separate machine dependencies.

list the files needed on the alpha.

specify man pages the new way.

Include files for pmax

__strerror() and __strsignal() have been broken out into their own files
and use message catalogs if NLS is defined.
Increased the size of char buffers used by strerror() and strsignal();
the error and signal strings may be much longer in some locales.

branches: 1.29.2;
Add strsignal() function like on Solaris.
We might want to be able to retrieve a locale-specific signal description
(from a message catalog) and we need a function call API for that feature.

We're supposed to include ${CPPFLAGS} when compiling .c files.

add Boyer-Moore string search routines, from Bostic. man page
needs to be fixed for mandoc, and RCSID's need to be added.

Changing the ns32k stuff.

memcpy.S and memmove.S on i386 are now separate.

Add strchr.S and strrchr.S for m68k.

Added some Sparc sources.

Also a memcpy.S for m68k.

Remove -p flags from .so builds.

Add memmove.S to m68k assembler stuff.

Use assembler versions of m68k stuff.

fix things so that memmove.so, et al., are built correctly on
machines w/o architecture-specific sources.

Changed occurance of MACHINE_ARCH == "hp300" to MACHINE_ARCH == "m68k"

get pc532 moved into ns32k; that's is MACHINE_ARCH

update for .S and MACHINE_ARCH

don't compiler strerror.c source here, and clean up.

Moved strerror.[c3] from libc/stdio to libc/string.
Since perror is not permitted to change strerror()'s static buffer, I have
changed both functions to pass their own buffers to the new library-internal
function _strerror() that actually does the error message string look up.
Split strerror manpage into strerror and perror manpages.

make an arch directory in libc, and move all machine dirs into it

Add swab.c or swab.s, as appropriate, to each machines source list instead
of always using swab.c

pc532 specifics.

Add RCS identifiers.

Add i386 assembly versions of bcmp & memcmp

enable memset & memchr.

Actually, just make memcpy() an alias for memmove().

Oops. Forgot to update the Makefile.
