libc: Reduce relative relocations in strftime().

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!

Spacing fixes. No actual change.

MFV of tzcode2009e:

Upgrade of the tzcode from 2004a to 2009e.

Changes are numerous, but include...

- New format of the output of zic, which supports both 32 and 64
bit time_t formats.

- zdump on 64 bit platforms will actually produce some output instead
of doing nothing for a looooooooong time.

- linux_base-fX, with X >= at least 8, will work without problems related
to the local time again.

The original patch, based on the 2008e, has been running for a long
time on both my laptop and desktop machine and have been tested by
other people.

After the installation of this code and the running of zic(8), you
need to run tzsetup(8) again to install the new datafile.

Pass a pointer to warn2 so the warn2 == IN_ALL would not be an
always-false condition.

Add glibc-style strftime(3) padding specifiers, namely, -(no padding),
_(use space as padding), and 0(zero padding).

These GNU extensions are widely used ones that is worthy for us to
have.

Merge changes from the tzcode2004a import. Wherever possible I tried to bring
us closer to the vendor branch.

Requested by: wollman

Remove a stale reference to %Ef and %EF from a comment.

Style: One space between "restrict" qualifier and "*".

- Add the 'restrict' qualifier to the function definition of
strftime(3) for IEEE Std 1003.1-2001 compliance and remove
excessive usage of the 'const' qualifier that was neither
present in the prototype in the publice header, nor in the
local prototype just above the function definition.
- Replace the K&R function definition with a ANSI-C one.
- Update the prototype of strftime(3) in its manual page.

Remove use of __P() (actually P()) from code now that it's no longer
available.

Fix the style of the SCM ID's.
I believe have made all of libc .c's as consistent as possible.

Get rid of non-standard %E[Ff] formats, userland apps already fixed

Relax local FreeBSD restrictions on 3 chars abbrev. name length and %c format
since they not allows POSIXly legal locale data. Currently, if relaxed form
POSIXly legal locale data will be used right now, some programs will be broken,
but it means that either locale data or programs must be fixed, not the library.

Introduce non-standard md_order (month/day order) locale field to be used later
via nl_langinfo(). Currently %EF and %Ef emulated using this field, but they
planned for remove in future in favour of nl_langinfo() test field.

Implement %F per POSIX

Implement ampm_fmt (%r) per POSIX

Back out snprintf -> sprintf change until I have time to look at it.

Hardcode c_fmt in a different way since used in nl_langinfo now

Catch up to latest chanage in timelocal structures exporting.

Remove _THREAD_SAFE and make libc thread-safe by default by
adding (weak definitions to) stubs for some of the pthread
functions. If the threads library is linked in, the real
pthread functions will pulled in.

Use the following convention for system calls wrapped by the
threads library:
__sys_foo - actual system call
_foo - weak definition to __sys_foo
foo - weak definition to __sys_foo

Change all libc uses of system calls wrapped by the threads
library from foo to _foo. In order to define the prototypes
for _foo(), we introduce namespace.h and un-namespace.h
(suggested by bde). All files that need to reference these
system calls, should include namespace.h before any standard
includes, then include un-namespace.h after the standard
includes and before any local includes. <db.h> is an exception
and shouldn't be included in between namespace.h and
un-namespace.h namespace.h will define foo to _foo, and
un-namespace.h will undefine foo.

Try to eliminate some of the recursive calls to MT-safe
functions in libc/stdio in preparation for adding a mutex
to FILE. We have recursive mutexes, but would like to avoid
using them if possible.

Remove uneeded includes of <errno.h> from a few files.

Add $FreeBSD$ to a few files in order to pass commitprep.

sprintf -> snprintf

Force %c to be "%a %Ef %T %Y" to eliminate problems with bad c_fmt

Submitted by: ru

There were so far only 42 different conversion specifications in
strftime(3), add another one. :) %z yields the local timezone's offset
in hours and minutes, as used in RFC822 headers. There's a precedence
for this in Lunux' libc, and Internet software (like Perl scripts)
start using it.

OKed by (wrt. the code freeze): jkh

%Ex -> %Ef to not conflict with POSIX
Add %EF (long months name / day order)
Check that O and E not intermixed
Add missing POSIX extension to example

Add %Ex extension to determine "%e %b" or "%b %e" order
Separate alternative for O and E cases

Implement new format specifier for strftime: %OB, alternative national
representation of the full month name. In the Russian locale, this alternative
will be "nominative case", useful when the date designate month as a whole.
E.g. month heading in a calendar. I hope it can be useful for some other
locales too.

$Id$ -> $FreeBSD$

Fixed printf format errors. Don't assume so many things about time_t.

Obtained from: partial merge of ADO version tzcode96h (was fully merged
in 1.10 but backed out in 1.11; the FreeBSD code for %s
was earlier, prettier but buggier).

Merged in better support of ISO 8601 from elsie.nci.nih.gov.
Added the conversion specifiers %g and %G, that are replaced
by the year which contains the greater part of the week in question.

Import strptime(3) into libc. We've got permission by Kevin Ruddy to
modify the original `no modifications' copyright message, and i've
included his mail into the source file.

The common localization functions between strptime(3) and strftime(3)
have been broken out into timelocal.[ch].

Revert $FreeBSD$ to $Id$

Include "setlocale.h" for _PathLocale like other parts already did

Should go in 2.2

Update the comment why range checking is not needed

Should go in 2.2

Make the long-awaited change from $Id$ to $FreeBSD$

This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.

Boy, I'm glad we're not using sup anymore. This update would have been
insane otherwise.

Add comment that range checking is already done at upper level
Kill snprintf left in collate.c from previous backout

Should go in 2.2

Move PATH_LOCALE handling to setlocale.c, simplify locale path building,
don't treat empty encoding as C encoding

Revert to old version of strftime.c; the new one doesn't work right.

Merge the recently-imported tzcode96h distribution (libc portion). The
part that does zic(8)/zdump(8) is still yet to be imported (but the old
zic and zdump will work just fine with these header files and the
data format has not changed).

Don't reset LC_TIME to C when it isn't neccessary

Restore %s format support from previous version

Fix default %c to be ctime-compatible as supposed (by Solaris too)

Implement locale-sensitive strftime () from ADO (heavily modified
by me). This probably loses for multibyte characters, but I have no
way of telling. I'll let ache decide whether to add this support to
startup_setlocale. Note that for this to make any sense at all, the
symlinks in /usr/share/locale must go. (For the moment, this doesn't
make any difference since there are no locales supplied.)

Obtained from: Arthur David Olson <ado@elsie.nci.nih.gov>

On snap 950210, format %s (print seconds from the epoch) is missing
from the code in strftime.c . This affects both the library code
and all the commands using it (e.g. date +%s).

Note that %s is not required by ANSI, but we've already got it in 1.1.5.1.
