Historically we have defined macros like

* `_LARGEFILE_SOURCE`
* `_LARGEFILE64_SOURCE`
* `_LARGE_FILES`
* `_FILE_OFFSET_BITS`

in `Configure.h` to activate large file support in system headers.  This
requires consuming projects to include the header at the beginning of
every translation unit in order to get the macros defined consistently.

Instead these macros should be defined by the build system on the
compiler command line.  Drop them from KWSys in favor of that approach.
The macros are not needed as often as they once were anyway.

Per-source copyright/license notice headers that spell out copyright holder
names and years are hard to maintain and often out-of-date or plain wrong.
Precise contributor information is already maintained automatically by the
version control tool.  Ultimately it is the receiver of a file who is
responsible for determining its licensing status, and per-source notices are
merely a convenience.  Therefore it is simpler and more accurate for
each source to have a generic notice of the license name and references to
more detailed information on copyright holders and full license terms.

Our `Copyright.txt` file now contains a list of Contributors whose names
appeared source-level copyright notices.  It also references version control
history for more precise information.  Therefore we no longer need to spell
out the list of Contributors in each source file notice.

Replace KWSys per-source copyright/license notice headers with a short
description of the license and links to `Copyright.txt` and online
information available from "https://cmake.org/licensing#kwsys".

Run the `filter-notices.bash` script to perform the replacements mechanically.
Manually fix up the shebang line in one file.

The clang-format tool sorts `#include` lines within contiguous blocks.
Separate blocks with blank lines and sort the include lines within them
so that clang-format does not re-order anything.

std::basic_filebuf::open(const wchar_t *) isn't part of C++ standard
and it's only present for MSVC but it isn't present in libstdc++ (MinGW)
so we implement this functionality using GNU libstdc++ stdio_filebuf
extension and _wfopen function.

Using iostream and cxxabi.h together causes a compile failure

 .../CC-gcc/include/c++/4.8.2/cxxabi.h", line 131: Error: Only one of a
 set of overloaded functions can be extern "C".

See https://community.oracle.com/thread/3644901 for details.

This only happens if the iostream include is before the cxxabi include.

The available solutions are: re-order the includes in
SystemInformation.cxx, skip the test for KWSYS_CXX_HAS_CXXABI, or cause
it to fail by adding the include.  Do the latter for now.

Add supprt for C++ name demangling during call stack
introspection. This will be enabled at compile time
if the required system libraries,header files, and
compiler features are detected. Add a method so that
the stack trace may be obtained on demand not just
from within the stack trace signal handler.

Add methods to report host memory total, host memory available,
process memory available, host memory used, and process memory
used. In this context memory is unavailable if there are resource
limits in place that would prevent its use. Such resource limits
assumed to be applied on a per host basis both to cooperatively
operating process groups, such as mpi programms running in parallel,
and to individual processes. When reporting host memory available
consult an application specified environment variable. When reporting
process memory available consult unix resource rlimits and an
application specified environment variable. The environmant variables
provide a means of communicating resource limits that are being
applied in a non-standard way.

The hash_fun.hxx header is configured whether FundamentalType is enabled
or not and so cannot depend on it.  Run the relevant platform tests
whether or not FundamentalType is on and configure the result directly
into hash_fun.  While at it, remove the dependence of SystemInformation
on FundamentalType too since it needs only information that we now
always compute.

The SystemTools::PutEnv function tries to provide the "putenv" API
without leaking memory.  However, the kwsysDeletingCharVector singleton
frees memory that may still be referenced by the environment table,
having been placed there by putenv.  If any static destruction or
processing by an external tool happens after the singleton is destroyed
and accesses the environment it will read invalid memory.

Replace use of putenv with setenv/unsetenv when available.  The latter
manage internal copies of the values passed instead of referencing the
original memory.  When setenv/unsetenv are not available use putenv with
a singleton that removes its values from the environment before freeing
their memory.  This requires an "unputenv" implementation.  On at least
some platforms it must be written in terms of "putenv" because other
APIs are not available and direct modification of the "environ" global
is not safe (e.g. on Windows there is interaction with "wenviron").
Fortunately either putenv("A=") or putenv("A") will remove "A" from the
environment on these platforms.  On other platforms fall back to direct
manipulation of "environ".

Also add UnPutEnv to the API and add a test for the behavior of both.

In KWSys IOStream we need to detect whether 'long long' exists but we do
not need its size.  We avoid using CHECK_TYPE_SIZE because it does not
work for types whose size varies across architectuers in Mac OS X
universal binaries.  See issue #9913.

This converts the KWSys license to a pure 3-clause OSI-approved BSD
License.  We drop the previous license clause requiring modified
versions to be plainly marked.  We also update the KWSys copyright to
cover the full development time range.

The 'binary' openmode does not exist on all compilers.  We define macro
<kwsys>_ios_binary, where <kwsys> is the KWSys namespace, to refer to
std::ios::binary if it exists and 0 otherwise.  Sample usage:

  kwsys_ios::ifstream fin(fn, kwsys_ios::ios::in | kwsys_ios_binary);

Some AIX/gcc version combinations the <cstdio> header breaks when large
file support is enabled.  See this GCC issue for details:

  http://gcc.gnu.org/bugzilla/show_bug.cgi?id=20366

We work around the problem by enhancing the configuration check for
large file support to include <cstdio> when available.  This will cause
LFS to be disabled when the above problem occurs.

ENH: Renamed kwsysPlatformCxxTests to kwsysPlatformTests and generalized it for multiple language tests (C and CXX).
