Run the `clang-format.bash` script to update all our C and C++ code to a
new style defined by `.clang-format`.  Use `clang-format` version 6.0.

* 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.

This is an empty commit that precedes an automatic application of
clang-format-6.0 to update the C++ style of our entire source tree.
This may be helpful to rebase a topic branch that was originally
based on a commit preceding the transition.  One may first rebase
the topic on this commit.  Then use one of the following approaches.

*   Rewrite the topic, including this commit, using `git filter-branch`
    `--tree-filter` with `clang-format.bash` to update the style in
    every commit.  Rebase the revised topic, excluding the rewrite of
    this commit, on the style transition commit.

OR

*   Add a `.git/info/grafts` entry to change the parent of the first
    commit in the topic from this commit to the style transition commit.
    Rewrite the topic using `git filter-branch --tree-filter` with
    `clang-format.bash` to update the style in every commit.  Then
    remove the graft, which was resolved by the filter.

See `git help filter-branch` and `git help repository-layout` for
details.

Update `.clang-format` with configuration to make the 6.0 format as
close as possible to what 3.8 produced before.  Then revise the style:

* Indent preprocessor directives (a feature new since 3.8)
* Add a newline and indentation before inheritance `:` and `,`

Rename the Git attribute identifying the format to include the
clang-format version number: `format.clang-format-6.0`.  This will aid
external infrastructure in knowing what version of the tool to run.

Preserve manually-formatted blocks.

For multi configuration generators let AUTORCC generate
the rcc output for all configurations.  This is a workaround
for the incomplete `$<CONFIG>` support in the DEPENDS and OUTPUT
clauses of a custom_command/custom_target.  Since we can't depend
on the per-config rcc output file we somehow must ensure the successful
rcc build for one configuration doesn't shadow the need to rcc rebuild
for a second configuration.

Closes #18006

By using a per .qrc lock file in AUTORCC, the same
`cmake -E cmake_autorcc ...` command can be called concurrently.

GCC 8.1.0 now gives an error if `strncpy` is called with a bound

`strcpy` as the length is known a priori.

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.

Fixes: #18033
Issue: #17206
