On Windows systems, the need to retain library directories should not
nomrally occur. This can only occur on Unix like systems where a shared
library is being linked that has a dependency on another library which
is not being found in the default directories (e.g. libgfortran on BSD)
This also works around an issue introduced by !1694 in that the Visual
Studio generator does not handle link flags passed in
`INTERFACE_LINK_LIBRARIES` correctly, causing problems when using that
generator with Intel MPI in certain circumstances.
Replace our hard-coded defaults for `/MD` and `/MDd` with a first-class
abstraction to select the runtime library from an enumeration of logical
names. We've long hesitated to do this because the idea of "runtime
library selection" touches on related concepts on several platforms.
Avoid that scope creep by simply defining an abstraction that applies
only when targeting the MSVC ABI on Windows.
Removing the old default flags requires a policy because existing
projects may rely on string processing to edit them and choose a runtime
library under the old behavior. Add policy CMP0091 to provide
compatibility.

The Gentoo case added by commit 1673923c30 (FindBoost: Add support for
Boost 1.67 with Python version suffixes, 2018-03-18, v3.11.0~3^2) left
out the `.` version component separator and instead duplicated the RPM
case. Add the missing `.` now.

VS 2019 Update 1 will fix its redist directories to be named `VC142`
instead of `VC141`. It will also use cl `19.21` instead of `19.20`
so we can use that to distinguish the versions.

The QtAutogen/ManySources test generates a number of source, header, .ui and
.qrc files that get AUTOMOC, AUTOUIC and AUTORCC processed. This stresses the
concurrency framework in `cmQtAutoMocUic` and should reveal any issues
with that.
This factors out the concurrency framework in `cmQtAutoGeneratorMocUic` to a
dedicated class `cmWorkerPool` which might be reused in other places.
`cmWorkerPool` supports fence jobs that require that
- all other jobs before in the queue have been processed before the fence
job processing gets started,
- no jobs later in the queue will be processed before the fence job processing
has been completed.
Fence jobs are needed where the completion of all previous jobs in the queue
is a requirement for further processing. E.g. in `cmQtAutoGeneratorMocUic`
the generation of `mocs_compilation.cpp` requires that all previous
source file parse jobs have been completed.
