This brings the functionality of `cmake -E create_symlink` and more to scripts.
The default behavior is to create hard links.
The `SYMBOLIC` argument can be used to create symlinks instead.
The `COPY_ON_ERROR` argument enables a fallback to copying the file in case the link fails.
The `RESULT <var>` retrieves the error message generated by the system.
It is set to "0" on success.

The allows `-E create_symlink` to work on Windows. It utilizes
`uv_fs_symlink`. I am still unsure exactly which Windows platforms will
work without requiring Administrator privileges or needing a user/group
with the "Create Symbolic Links" User Rights. It does work with my
Windows 10 Pro with Developer Mode turned on. In the test suite check
that the symlink either worked or failed with a permissions error.
Use recent changes in cmSystemTools::FileExists to check that a symlink
is broken.
The use of `uv_fs_realpath` introduced by commit v3.11.0-rc1~445^2~1
(cmSystemTools: Implement GetRealPath on Windows, 2017-10-02) causes
`subst` drives to be expanded on Windows, breaking existing use cases.
Revert its use until an alternative implementation can be chosen.
Preserve the behavior introduced by commit v3.11.0-rc1~445^2
(cmTimestamp: For symlinks switch to timestamp of resolved path,
2017-10-02) by retaining use of `uv_fs_realpath` in a function of
a different name.

* Change some functions to take `std::string` instead of
`const char*` in the following classes: `cmMakeFile`, `cmake`,
`cmCoreTryCompile`, `cmSystemTools`, `cmState`, `cmLocalGenerator`
and a few others.
* Greatly reduce using of `const char*` overloads for
`cmSystemTools::MakeDirectory` and `cmSystemTools::RelativePath`.
* Remove many redundant `c_str()` conversions throughout the code.

This commit continues the changes made in CTest to support std::chrono
by
applying it throughout every component where a duration was used.
No functional change intended.
Since libuv commit v1.14.1~7 (win: add uv__once_init() calls,
2017-08-30) the libuv initialization of the file translate mode may take
place even if we do not use a uv loop. This change was included in our
libuv update commit f4a26c748b (libuv 2018-01-19). Therefore use of
libuv even through `cmSystemTools::GetRealPath` in any executable may
trigger its file translate mode setting.
Factor out the logic added to `cmake.exe` by commit v3.9.0-rc4~10^2
(cmake: Fix default file translate mode when using libuv, 2017-06-13)
and re-use to initialize all executables.
Issue: #16962
The KWSys `SystemTools::SplitProgramFromArgs` implementation goes into
an infinite loop when the value is just " " (a space). Since the
"program path with unquoted spaces plus command-line arguments"
operation it is trying to provide is poorly defined (string parsing
should not depend on filesystem content), just stop using it.
Instead consider the main two use cases the old approach tried to handle:
* The value is the name or absolute path of a program with no quoting
or escaping, but also no command-line arguments. In this case we
can use the value as given with no parsing, and assume no arguments.
* The value is a command-line string containing the program name/path
plus arguments. In this case we now assume that the command line
is properly quoted or escaped.

The internal tool "cmake_ninja_depends" now supports reading the list of ddi
files from a reponse file to circumvent Windows command line length limits.
Use this response file for dyndep rule on Windows.
Move the logic to cmSystemTools to be shared among the generators.
Revise the implementation and add comments justifying each possible
source for a limit.
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 CMake 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". The online URL also handles
cases of modules being copied out of our source into other projects, so we
can drop our notices about replacing links with full license text.
Run the `Utilities/Scripts/filter-notices.bash` script to perform the majority
of the replacements mechanically. Manually fix up shebang lines and trailing
newlines in a few files. Manually update the notices in a few files that the
script does not handle.
Add support for natural string order by comparing non-numerical
character directly and numerical number by firstly collecting contiguous
digits. The order is defined by the `strverscmp(3)` manual [1].

Run the `Utilities/Scripts/clang-format.bash` script to update
all our C++ code to a new style defined by `.clang-format`.
Use `clang-format` version 3.8.
* If you reached this commit for a line in `git blame`, re-run the blame
operation starting at the parent of this commit to see older history
for the content.
* See the parent commit for instructions to rebase a change across this
style transition commit.
Sort include directives within each block (separated by a blank line) in
lexicographic order (except to prioritize `sys/types.h` first). First
run `clang-format` with the config file:
---
SortIncludes: false
...
Commit the result temporarily. Then run `clang-format` again with:
---
SortIncludes: true
IncludeCategories:
- Regex: 'sys/types.h'
Priority: -1
...
Commit the result temporarily. Start a new branch and cherry-pick the
second commit. Manually resolve conflicts to preserve indentation of
re-ordered includes. This cleans up the include ordering without
changing any other style.
Use the following command to run `clang-format`:
$ git ls-files -z -- \
'*.c' '*.cc' '*.cpp' '*.cxx' '*.h' '*.hh' '*.hpp' '*.hxx' |
egrep -z -v '(Lexer|Parser|ParserHelper)\.' |
egrep -z -v '^Source/cm_sha2' |
egrep -z -v '^Source/(kwsys|CursesDialog/form)/' |
egrep -z -v '^Utilities/(KW|cm).*/' |
egrep -z -v '^Tests/Module/GenerateExportHeader' |
egrep -z -v '^Tests/RunCMake/CommandLine/cmake_depends/test_UTF-16LE.h' |
xargs -0 clang-format -i
This selects source files that do not come from a third-party.

The OUTPUT_NORMAL value is not really "normal" and has only one caller.
Rename it to OUTPUT_FORWARD to clarify that we are explicitly forwarding
the output.
