to reflect the new license. These used slightly different spellings that
defeated my regular expressions.
We understand that people may be surprised that we're moving the header
entirely to discuss the new license. We checked this carefully with the
Foundation's lawyer and we believe this is the correct approach.
Essentially, all code in the project is now made available by the LLVM
project under our new license, so you will see that the license headers
include that license only. Some of our contributors have contributed
code under our old license, and accordingly, we have retained a copy of
our old license notice in the top-level files in each project and
repository.

Summary:
[libc++] Exclude posix_l/strtonum fallback inclusion for newlib > 2.4
r338122 changed the linkage of some methods which revealed an existing ODR violation, e.g.:
projects/libcxx/include/support/xlocale/__posix_l_fallback.h:83:38: error: 'internal_linkage' attribute does not appear on the first declaration of 'iswcntrl_l'
inline _LIBCPP_INLINE_VISIBILITY int iswcntrl_l(wint_t c, locale_t) {
^
lib/include/wctype.h:55:12: note: previous definition is here
extern int iswcntrl_l (wint_t, locale_t);
These were added to newlib in 2.4 [1] [2], so move them to the already existing include guard.

Newlib 2.5 added the locale management functions, so it should not
include __nop_local_mgmt.h. This change adds proper guard around that
include statement.
For newlib 2.4, some releases contain these functions and some don't,
and they all have the same version numbers. This patch will work
properly with the initial "2.4.0" release which does not include these
functions and require __nop_local_mgmt.h.
This has been tested against newlib 2.2 and 2.5, and also sanity
checks against other different version numbers.

The various _l locale extension functions originate from very
different places. Some come from POSIX, some are BSD extensions,
and some are shared BSD and GLIBC extensions. This patch tries to
group the local extension reimplementations by source. This should
make it easier to make libcxx work with POSIX compliant C libraries
that lack these extensions.
The fallback locale functions are also useful on their own for other
lightweight platforms. Putting these fallback implementations in
support/xlocale should enable code sharing.
I have no access to a newlib system or an android system to build
and test with. I _do_ have access to a system without any of the _l
locale extensions though, and I was able to ensure that the new
__posix_l_fallback.h and __strtonum_fallback.h didn't have any massive
problems.

This is one part of many of a locale refactor. See
http://reviews.llvm.org/D17146 for an idea of where this is going.
For the locale refactor, the locale management functions (newlocale,
freelocale, uselocale) are needed in a separate header from the various _l
functions. This is because some platforms implement the _l functions in terms
of a locale switcher RAII helper, and the locale switcher RAII helper needs
the locale management functions. This patch helps pave the way by getting all
the functions in the right files, so that later diffs aren't completely
horrible.
The "do-nothing" / "nop" locale functions are also useful on their own for
other lightweight platforms. Putting these nop implementations in
support/xlocale should enable code sharing.
Unfortunately, I have no access to a newlib system to build and test with, so
this change has been made blind.
