libs/posix: Implemented new locale functions

Implemented the missing POSIX functions in <locale.h>:
newlocale, duplocale, uselocale, and freelocale, and also
provided missing type definitions for <locale.h>.

Implemented missing POSIX locale-based function variants.

Modified LocaleBackend so that it could support thread-local
locales.

Some glibc-like locale-related variables supporting
ctype and printf family of functions have also been updated
to reflect the thread-local variables present in the latest
glibc sources.

As there have been some modifications to global symbols
in libroot, libroot_stubs.c has been regenerated.

Remove B_FILE_NOT_FOUND from public headers.

Now that it is not used anywhere in the source tree following
previous commits.

Add EHOSTDOWN to strerror()

How come we missed the case B_DONT_DO_THAT in strerror() ???

Add missing strings to strerror() for hrev46649

Add new error codes B_PARTIAL_{READ,WRITE}

B_POSIX_ENOMEM is obviously an error...

* was wrongly reported as "No error"

* Since the Media/Translation Kit errors are now in Errors.h as well, we don't
need to include those two anymore.

Added missing ENOATTR text.

Experimental approach to tackle the problem with Be's negative error codes and
ported software:
* If the macro B_USE_POSITIVE_POSIX_ERRORS is defined the POSIX error code
constants (ENOMEM, EINTR,...) will have positive values.
* Introduced the macros B_TO_{POSITIVE,NEGATIVE}_ERROR() which do convert a
given error code to a positive/negative value.
* Added static library libposix_error_mapper.a that overrides all POSIX
functions (save the ones I forgot to add :-)) directly meddling with error
codes (having them as parameter or returning them) dealing with the
positive<->negative error code conversions. The functions have hidden
visibility, so they affect only the shared object they are linked into.
* So ideally all one has to do is to build a ported software with
-DB_USE_POSITIVE_POSIX_ERRORS and -lposix_error_mapper and be good with
respect to error code problems.
* Potential issues:
- When mixing ported and Haiku native code, i.e. using Haiku native code in
a ported software or using a ported library in a Haiku native application
care must be taken to convert error codes where the two interface. That's
what the B_TO_{POSITIVE,NEGATIVE}_ERROR() macros are supposed to be used
for.
- A ported static library can obviously not be linked directly against
-lposix_error_mapper. The shared object linking a against the ported static
library has to do that. The previous point applies when that causes mixing
with Haiku native code.
- When dependent ported libraries are used probably all of them should use
the error mapping.

Comments welcome.

New error codes:
- B_SHUTDOWN_CANCELLED: The shutdown process was cancelled (most likely by
the user).
- B_SHUTTING_DOWN: An operation cannot be performed, since the system is
shutting down (e.g. BApplication creation).

instead it now says "No Error".
