MFC: sync with -CURRENT's stdtime code

2002-03-12T17:24:54+00:00

This MFC brings to -STABLE following changes/features:

. get rid of non-standard %E[Ff] formats
. add %F per POSIX
. add %r per POSIX (ampm_fmt)
. hardcode c_fmt in a different way since used in nl_langinfo now
. make '%A' and '%a', '%B' and '%b' same per POSIX
. introduce non-standard md_order (month/day order locale field).
  This field is available to user-land apps via nl_langinfo(3)
  and supposed to replace all usages of %E[Ff] in more correct way.
. allow POSIX legal data on 3 chars abbrev, name length
  and %c format

WARNING: please beware about this commit. It can trigger some
hidden or implicit problems with locale/time specific functions or
related/dependent stuff in userland applications. Please report
anything unusual!

Simplify sytem call renaming. Instead of _foo() <-- _libc_foo <-- foo(),

2000-01-27T23:07:25+00:00

just use _foo() <-- foo().  In the case of a libpthread that doesn't do
call conversion (such as linuxthreads and our upcoming libpthread), this
is adequate.  In the case of libc_r, we still need three names, which are
now _thread_sys_foo() <-- _foo() <-- foo().

Convert all internal libc usage of: aio_suspend(), close(), fsync(), msync(),
nanosleep(), open(), fcntl(), read(), and write() to _foo() instead of foo().

Remove all internal libc usage of: creat(), pause(), sleep(), system(),
tcdrain(), wait(), and waitpid().

Make thread cancellation fully POSIX-compliant.

Add three-tier symbol naming in support of POSIX thread cancellation

points.  For library functions, the pattern is __sleep() <--
_libc_sleep() <-- sleep().  The arrows represent weak aliases.  For
system calls, the pattern is _read() <-- _libc_read() <-- read().

%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

1999-09-11T21:35:21+00:00

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.

Replace memory leaking instances of realloc with non-leaking reallocf.

1998-09-16T04:17:47+00:00

In some cases replace if (a == null) a = malloc(x); else a =
realloc(a, x); with simple reallocf(a, x).  Per ANSI-C, this is
guaranteed to be the same thing.

I've been running these on my system here w/o ill effects for some
time.  However, the CTM-express is at part 6 of 34 for the CAM
changes, so I've not been able to do a build world with the CAM in the
tree with these changes.  Shouldn't impact anything, but...
