Docs added by commit f3e0b6f1 (CTestCoverageCollectGCOV: Add module to
run gcov, 2015-01-14, v3.2.0-rc1~79^2) accidentally called the function
`cdash_coverage_collect_gcov`.  Rename `cdash` to `ctest`.

When passing a `<header>` inside a generator expression, the closing
`>` needs to be encoded as `$<ANGLE-R>`.  Add an example to the docs.

Revert commit b2fd479d (FindBinUtils: Use the compiler to get the path
to compiler tools, 2019-09-22, v3.16.0-rc1~51^2).  The compiler's answer
may incorrectly come from the `PATH`.  Another approach will be needed.

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

Fixes: #19925

This way you can have .cpp files compiled as ObjC++.

Fixes: #19926

llvm-rc expects versioning as having four items, it fails otherwise.

On unknown platforms we issue a message instructing users to post to
our mailing list to add support for the platform.  Refer them to the
CMake Discourse Forum instead.

Some of the links refer to URLs that are now redirected.  Update them.

The CMake Discourse Forum at `discourse.cmake.org` supersedes the
mailman-based mailing lists.

Replace the mailing list email address with one on
`discourse.cmake.org`.

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.

Fixes: #19927

Replace the post-release development announcement to the mailing list
with a post to the appropriate category on `discourse.cmake.org`.

Also includes variants like hw -> res

Renaming these ahead of other refactoring which will use the
previous names. The previous names more accurately reflect their
purpose after this commit anyway (talking about locking and
unlocking rather than allocating and deallocating).

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

The corresponding test property `PROCESSES` has been renamed to
`RESOURCE_GROUPS`.

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`.
