There are two common sigpause variants, both of which take an int argument.
If you request _XOPEN_SOURCE or _GNU_SOURCE, you get the System V version,
which removes the given signal from the process's signal mask; otherwise
you get the BSD version, which sets the process's signal mask to the given
value.

The locale_t type is provided by <xlocale.h> on Linux, FreeBSD, and Darwin.
While, like on some of those systems, it is automatically included by
<locale.h> with the proper feature test macros, its presence under this
particular name is still presumed in real-world software.

Note that this always returns with dli_sname and dli_saddr set to NULL,
indicating no symbol matching addr could be found.

Give more elements ids, so random ids aren't assigned to them, so anchors

GNU no longer encourages the use of documentation mirrors, to avoid
referring to obsolete documentation. Also www.fsf.org/manual/ is
just a redirect to www.gnu.org/manual/
Links to using-utils.html #fragments are no longer correct as each utility
is now a separate page, since 646745cb.
indiana.edu seems to have moved XLiveCD information, without a redirect.
Linking to clean_setup.pl on cygwin.com doesn't work, as direct downloads
aren't allowed, so instead state where it can be found on a mirror.

This patch adds pthread_getname_np and pthread_setname_np.
These were added to glibc in 2.12[1] and are also present in some form on
NetBSD and several UNIXes.
The code is based on NetBSD's implementation with changes to better match
Linux behaviour.
Implementation quirks:
* pthread_setname_np with a NULL pointer segfaults (as linux)
* pthread_setname_np returns ERANGE for names longer than 16 characters (as
linux)
* pthread_getname_np with a NULL pointer returns EFAULT (as linux)
* pthread_getname_np with a buffer length of less than 16 returns ERANGE (as
linux)
* pthread_getname_np truncates the thread name to fit the buffer length.
This guarantees success even when the default thread name is longer than 16
characters, but means there is no way to discover the actual length of the
thread name. (Linux always truncates the thread name to 16 characters)
* Changing program_invocation_short_name changes the default thread name (on
linux, it has no effect on the default thread name)
I'll leave it up to you to decide if any of these matter.
This is implemented via class pthread_attr to make it easier to add
pthread_attr_[gs]etname_np (present in NetBSD and some UNIXes) should it
ever be added to Linux (or we decide we want it anyway).

The default UI language returned by GetUserDefaultUILanguage does not
necessarily reflect what the user really wants. E. g., the system could
be en_US, but the desired language is en_CA, without having a CA langpack
installed.
Changing the settings under "Languages" and changing the keyboard layout
is only affecting the so-called "Input language", while what's returned
by GetUserDefaultUILanguage is the "Display language". Changing the
latter requires installing MUI langpacks.
Thus, we introduce a way to fetch the "Input language" using the -i or
--input option.
Also clean up documentation of locale(1).
