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!

3d74e220a5 strptime(3) confused July with June with the fr_FR locale.
When parsing the month "juillet" (abbr "jul"), %B recognized it as
"juin" (abbr "jui") because the full name of the month names is
checked at the same time as the abbrevation.

The new behaviour checks the full names first before checking the
abbrevation names.

methods are only invoked when __isthreaded is true at which point it is safe

dfc79e892f 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.

  posix1e: acl_size.c has been never compiled in,

  some symbols are specific only to some architectures,
  e.g., ___tls_get_addr is only defined on i386.

  __htonl, __htons, __ntohl and __ntohs are no longer

9685457382 On FreeBSD/arm, any value > 50 bits will result in a rediculously huge
number being returned for mktime and timegm calls.  Choose 48 because
that works well.  This does reduce the dynamic range of tm_year from
about 2 billion years down to "only" about 9 million years.  Please
contact me if this restriction poses a problem.

Due to the complexity of the code, I admit that I didn't trace down
what, exactly, was overflowing with longer bits.  This fixes software
that we run on the embedded systems we have.

ee4dc2a402 struct tm.tm_year is listed as 'years since 1900', and is signed. On
64 bit systems, years roughly -2^31 through 2^31 can be represented in
time_t without any trouble.  32 bit time_t systems only range from
roughly 1902 through 2038.  As a consequence, none of the date munging
code for all the various calendar tweaks before then is present.  There
are other problems including the fact that there was no 'year zero' and
so on.  So rather than get excited about trying to figure out when the
calendar jumped by two weeks etc, simply disallow negative (ie: prior to
1900) years.

This happens to have an important side effect.  If you bzero a 'struct
tm', it corresponds to 'Jan 0, 1900, 00:00 GMT'.  This happens to be
representable (after canonification) in 64 bit time_t space.  Zero tm
structs are generally an error and mktime normally returns -1 for them.
Interestingly, it tries to canonify the 'jan 0' to 'dec 31, 1899', ie:
year -1.  This conveniently trips the negative year test above, which
means we can trivially detect the null 'tm' struct.

This actually tripped up code at work. :-/  (Don't ask)

c91e947dbd Detect range errors when using the %s specifier. Previously, LONG_MAX
was rejected as a range error, while any values less than LONG_MIN
were silently substituted with LONG_MIN.  Furthermore, on some
platforms `time_t' has less range than `long' (e.g. alpha), which may
give incorrect results when parsing some strings.
