CMake used this to preserve symlinks through realpath operations, but
its presence caused some undesired side effects.  Those realpath
operations are being replaced with a hand-written alternative that
explicitly preserves symlinks when possible and does not have the side
effects.  Therefore we no longer need the path translation map.

When determining full paths, CMake would treat the as-called path for
the source and build directories as real paths even if they were
symlinks. This causes problems when determining the relative path
between the source and build directories when they are symlinks.

Take the following setup as an example:

    /mnt/src/project/
        src/
        build/ -> /mnt/builds/project/build

With the translation map and /mnt/src/project/build/ as the build
directory, CMake would use ../src as the relative path to the source
tree from the build tree rather than ../../../src/project/src and
lookups using ../src would fail. If the build directory were instead
used *as* /mnt/builds/project/build, everything would work just
fine.

This patch makes the core logic which does this logic optional so that
it can be experimented with in CMake itself.

When building with C++11 or greater, use the `nullptr` keyword.

Some C++ compilers now warn when a switch case falls through to another
case, but compilers vary in how to suppress the warning with an explicit
fallthrough specifier.  Provide a macro for the specifier.

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names and years are hard to maintain and often out-of-date or plain wrong.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.

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.

with old STL versions.

namespace instead.  Drop the now-unused KWSYS_STL_HAVE_STD check.

Define KWSYS_DO_NOT_CLEAN_PUTENV only for the implementation.  It does
not need to be configured in the interface of "Configure.hxx".

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.

Put a flag in that will stop system tools from deleting system environment memory on exit, as it can cause gcov to crash the programs.

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);

All KWSys C symbol names begin with the KWSYS_NAMESPACE defined at
configuration time.  For ease of editing we write canonical names with
the prefix 'kwsys' and use macros to map them to the configured prefix
at preprocessing time.  In the case of standalone KWSys, the prefix is
'kwsys', so the macros were previously defined to their own names.

We now skip defining the macros in the identity case so that the final
symbol names are never themselves macros.  This will allow the symbols
to be further transformed behind the scenes to help linkers in special
cases on some platforms.

COMP: Added KWSys try-compiles KWSYS_STL_HAS_ALLOCATOR_TEMPLATE and KWSYS_STL_HAS_ALLOCATOR_OBJECTS.  Needed for more old-stl support in the hashtable.

COMP: Added KWSYS_CXX_HAS_CSTDDEF try-compile to KWSys to provide kwsys/cstddef header (to get size_t for hash_fun.hxx).

ENH: Added KWSys try-compiles KWSYS_STL_HAS_ITERATOR_TRAITS, KWSYS_STL_HAS_ITERATOR_CATEGORY, KWSYS_STL_HAS___ITERATOR_CATEGORY, and KWSYS_STL_HAS_ALLOCATOR_NONTEMPLATE to get the hash table to compile on old HP and Sun compilers.

ENH: Added KWSYS_CXX_HAS_ARGUMENT_DEPENDENT_LOOKUP try-compile to KWSys.  Needed to optionally bring hash table comparison operators into the global namespace when argument dependent lookup is not supported.

COMP: Added KWSYS_STL_HAS_ALLOCATOR_MAX_SIZE_ARGUMENT check for non-standard argument to stl allocator<>::max_size method.  Needed for kwsys hashtable to compile on Sun CC.

ENH: Do kwsys testing as part of cmake testing, command line arguments are not experimental and add simple test for systemtools

ENH: Adding SGI hash_map and hash_set implementation ported from STL to KWSys.  This also adds try-compiles for KWSYS_STL_HAS_ALLOCATOR_REBIND, KWSYS_CXX_HAS_FULL_SPECIALIZATION, KWSYS_CXX_HAS_MEMBER_TEMPLATES, and KWSYS_CXX_HAS_NULL_TEMPLATE_ARGS.

ENH: Added istream and ostream operators for stl string in KWSys when using old streams that do not provide them.
