7165803bdb Revert r272122
The patch still needs to be more robust and it broke the
build on MIPS so revert it for now while all the issues
are fixed.

1d2b292826 Add strptime(3) support for %U and %W
Add support for the missing POSIX-2001 %U and %W features: the
existing  FreeBSD strptime code recognizes both directives and
validates that the week number lies in the permitted range,
but then simply discards the value.

Initial support for the feature was written by Paul Green with
important fixes by Andrey Chernov. Additional support for
handling tm_wday/tm_yday was written by David Carlier.

51325ca40d Always seek back to the beginning of a regular directory, even if the
previous seek location was 0.  Without this, readdir() would see
dd_loc of zero and call getdirentries() which would start reading
entries at the current seek location of the directory ignoring the
first batch of entries.  Also, rewinddir() should always seek so that
it reads the directory from the beginning to get updated entries.

72b4dec586 Add lock annotations to the header files of our threading libraries.
This change extends all of the functions present in the <pthread.h> and
<threads.h> headers to have lock annotations. This will allow Clang to
warn about the following:

- Locking a function twice,
- Unlocking a function without a mutex being locked,
- Forgetting to unlock a mutex before returning,
- Destroying or reinitializing a mutex that is currenty locked,
- Using an unlocked mutex in combination with a condition variable.

Enabling these annotations already allowed me to catch a bug in one of
our userspace tools (r270749).
