[PATCH 00/17] Fix MSVC support, at long last

["Johannes Schindelin via GitGitGadget" <gitgitgadget@gmail.com>]

Philip Oakley and Jeff Hostetler worked quite a bit on getting Git to
compile with MS Visual C again, and this patch series is the culmination of
those efforts. With these patches, it is as easy as

make MSVC=1

Note: the patches went through quite the number of iterations. For example,
for a long time we targeted Visual Studio 2015, and used NuGet packages for
the dependencies (such as OpenSSL, cURL, etc), while the current iteration
targets Visual Studio 2017 and uses vcpkg
[https://docs.microsoft.com/en-us/cpp/vcpkg?view=vs-2017] for dependencies.
Hopefully I did not forget to remove any remnants of those previous
versions.

Please also note that this patch series is part 1 of 3 in a bigger story:
the next patch series will add support to build Git in Microsoft Visual
Studio, and the third patch series will add Continuous Testing by adding an
MSVC build and a corresponding parallelized test job to our Azure Pipeline.
