ff847ecb82 In threaded processes, destroy the mutex atexit_mutex when we've
finished using it.  This allows the mutex's allocated memory to be
freed.

This is one sense a rather silly change, since at this point we're
less than a microsecond away from calling _exit; but fixing this
memory leak is likely to make life easier for anyone trying to
track down other memory leaks.

5b3fab81ab Fix a bug due to a type conversion from 64 to 32 bits. The side effect of
this type conversion is the high bits which were used to indicate if a
special character was a literal or special were dropped. As a result, all
special character were treated as special, even if they were supposed to
be literals.

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.

e27ed89aef Merger of the quota64 project into head.
This joint work of Dag-Erling Smørgrav and myself updates the
FFS quota system to support both traditional 32-bit and new 64-bit
quotas (for those of you who want to put 2+Tb quotas on your users).

By default quotas are not compiled into the kernel. To include them
in your kernel configuration you need to specify:

options         QUOTA                   # Enable FFS quotas

If you are already running with the current 32-bit quotas, they
should continue to work just as they have in the past. If you
wish to convert to using 64-bit quotas, use `quotacheck -c 64';
if you wish to revert from 64-bit quotas back to 32-bit quotas,
use `quotacheck -c 32'.

There is a new library of functions to simplify the use of the
quota system, do `man quotafile' for details. If your application
is currently using the quotactl(2), it is highly recommended that
you convert your application to use the quotafile interface.
Note that existing binaries will continue to work.

Special thanks to John Kozubik of rsync.net for getting me
interested in pursuing 64-bit quota support and for funding
part of my development time on this project.

702f62fb48 getcwd(3): Clarify that EACCES may or may not be checked.
POSIX permits but does not require checking access on the current and parent
directories.

Because various programs do not like it if getcwd(3) fails, it seems best
to avoid checking access as much as possible. There are various reports in
GNATS about this (search for getcwd).

Our getcwd(3) implementation first queries the kernel for the pathname
directly, which does not check any permissions but sometimes fails, and then
falls back to reading all parent directories for the names.

b7e9bee71c While SPARC V9 allows tininess to be detected either before or after
rounding (impl. dep. #55), the SPARC JPS1 responsible for SPARC64 and
UltraSPARC processors defines that in all cases  tininess is detected
before rounding therefore rounding up to the smallest normalized number
should set the underflow flag. This change is needed for using SoftFloat
on sparc64 for reference purposes.
