These modules are not meant to be included by user code, they are
only an internal implementation detail for CPack. Having them live
in the main Modules directory with documentation was misleading, so
they have been moved into Modules/Internal/CPack, and their
documentation has been stripped following its move into the new
"CPack Generators" section. No-op modules which contained only
documentation have been removed entirely.
The only module that hasn't been moved is CPackIFW, because it
contains user-facing macros which would be lost if it were moved.
So, the CPackIFW module has been updated with a note explaining what
needs to (eventually) happen.
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.

Create a CPack generator that uses `nuget.exe` to create packages:
https://docs.microsoft.com/en-us/nuget/what-is-nuget
NuGet packages could be easily produced from a `*.nuspec` file (running
`nuget pack` in the directory w/ the spec file). The spec filename does
not affect the result `*.nupkg` name -- only `id` and `version` elements
of the spec are used (by NuGet).
Some implementation details:
* Minimize C++ code -- use CMake script do to the job. It just let the
base class (`cmCPackGenerator`) to preinstall everything to a temp
directory, render the spec file and run `nuget pack` in it, harvesting
`*.nupkg` files...;
* Ignore package name (and use default paths) prepared by the base class
(only `CPACK_TEMPORARY_DIRECTORY` is important) -- final package
filename is a responsibility of NuGet, so after generation just scan the
temp directory for the result `*.nupkg` file(s) and update
`packageFileNames` data-member of the generator;
* The generator supports _all-in-one_ (default), _one-group-per-package_
and _one-component-per-package_ modes.
