Closes: #19967

Combine `--repeat-until-fail`, `--repeat-until-pass`, and
`--repeat-after-timeout` to create a single `--repeat <mode>:<n>`
option.  Retain `--repeat-until-fail` too because that has been
available in previous releases.

In commit da5ac4bb (cpack: Add `CPACK_INSTALL_CMAKE_CONFIGURATIONS`
variable, 2019-07-10, v3.16.0-rc1~165^2) we added support for running
the `cpack -C ...` command-line with multiple configurations.  Add an
explicit test for this.

In commit da5ac4bb (cpack: Add `CPACK_INSTALL_CMAKE_CONFIGURATIONS`
variable, 2019-07-10, v3.16.0-rc1~165^2) we added both the variable
and support for `cpack -C` with multiple configurations.  Drop the
variable because the `package` target cannot ensure that all of the
configurations are built.  Keep the command-line interface so that
it can be used manually in scripts.

There is no reason to skip the generated files, in case of problems
one can use the SKIP_UNITY_BUILD_INCLUSION property.

- fix the typo in `foreach` documentation
- fix broken `foreach(... IN ITEMS ... LISTS ...)`
- add tests of `foreach` for existed functionality and fixes

Refactoring in commit 2d888e33 (cmSourceFile: Rename mutating
GetFullPath() overload, 2019-08-29, v3.16.0-rc1~160^2) accidentally left
the paths to `CMakeLists.txt` files empty in generated Xcode project
files.

Also includes variants like hw -> res

Only changes the user-visible effects of renaming hardware
allocation to resource allocation. Code changes are the minimum
needed to achieve that.

The `PROCESSES` test property name added for CMake 3.16 is too close to
the existing `PROCESSORS` test property.  Furthermore, the property in
principle specifies groups of resources organized in a way that is
meaningful to a particular test.  The groups may often correspond to
processes but they could have other meanings.  Since the property name
`PROCESSES` has not been in a final 3.16 release yet, simply rename it
to `RESOURCE_GROUPS`.

A case added by commit 39ac8b4e (ctest: Add --repeat-after-timeout
option, 2019-10-29) includes a success-case timeout of 2 seconds.  That
is too short when running under valgrind, so extend it to 5 seconds.

Closes #19638.

These are not useful in nightly testing.

Add an option to re-run tests if they timeout.  This will help tolerate
sporadic timeouts on busy machines.

Add an option to re-run tests if they fail.  This will help tolerate

This fixes two errors: not accounting for the trailing null and a
misunderstanding of what std::numeric_limits::digits10 means.

Fixes: #18386

Since commit 97cc29c7 (VS: Teach generators how to mark per-config
source files, 2017-04-10, v3.9.0-rc1~268^2~2) the VS generators have
known how to generate per-config sources.  We've now converted most
other code paths to support per-config sources, so drop the check
that disallows it.

This leaves only per-config support for precompiled headers and unity
build transformations, but those are optional features that can be
addressed later.

Add a `VS_DOTNET_DOCUMENTATION_FILE` target property to tell VS
generators to add a `DocumentationFile` setting in `.csproj` files.

Since commit 4ca0526f (cmake: Pass -S and -B into PreLoad.cmake and -C
scripts, 2019-08-20, v3.16.0-rc1~195^2) the value of `CMAKE_SOURCE_DIR`
is the source directory rather than the current working directory.
This was correct on its own, but the place storing that value is also
used as the base for relative paths specified on the command line.
The latter should of course be relative to the current working
directory.

The fix is to switch to use a full path internally, unless a full path
is already specified.  Add tests for the behaviour of `-C` under these
four circumstances:

    {with -S, without -S} x {full path, relative path}
