The entire idea of generating the VS solution makes only sense if we
generate it via Continuous Integration; otherwise potential users would
still have to download the entire Git for Windows SDK.
If we pre-generate the Visual Studio solution, Git can be built entirely
within Visual Studio, and the test scripts can be run in a regular Git
for Windows (e.g. the Portable Git flavor, which does not include a full
GCC toolchain and therefore weighs only about a tenth of Git for
Windows' SDK).
So let's just add a target in the Makefile that can be used to generate
said solution; The generated files will then be committed so that they
can be pushed to a branch ready to check out by Visual Studio users.
To make things even more useful, we also generate and commit other files
that are required to run the test suite, such as templates and
bin-wrappers: with this, developers can run the test suite in a regular
Git Bash after building the solution in Visual Studio.
Note: for this build target, we do not actually need to initialize the
`vcpkg` system, so we don't.

With this patch, Git can be built using the Microsoft toolchain, via:
make MSVC=1 [DEBUG=1]
Third party libraries are built from source using the open source
"vcpkg" tool set. See https://github.com/Microsoft/vcpkg
On a first build, the vcpkg tools and the third party libraries are
automatically downloaded and built. DLLs for the third party libraries
are copied to the top-level (and t/helper) directory to facilitate
debugging. See compat/vcbuild/README.
A series of .bat files are invoked by the Makefile to find the location
of the installed version of Visual Studio and the associated compiler
tools (essentially replicating the environment setup performed by a
"Developer Command Prompt"). This should find the most recent VS2015 or
VS2017 installation. Output from these scripts are used by the Makefile
to define compiler and linker pathnames and -I and -L arguments.
The build produces .pdb files for both debug and release builds.
Note: This commit was squashed from an organic series of commits
developed between 2016 and 2018 in Git for Windows' `master` branch.
This combined commit eliminates the obsolete commits related to fetching
NuGet packages for third party libraries. It is difficult to use NuGet
packages for C/C++ sources because they may be built by earlier versions
of the MSVC compiler and have CRT version and linking issues.
Additionally, the C/C++ NuGet packages that we were using tended to not
be updated concurrently with the sources. And in the case of cURL and
OpenSSL, this could expose us to security issues.

In 60f487ac0ef (Remove common-cmds.h, 2018-05-10), we forgot to adjust
this README when removing the common-cmds.h file.

These scripts generate projects for the MSVC IDE (.vcproj files) or
QMake (.pro files), based on the output of a 'make -n MSVC=1 V=1' run.
This enables us to simply do the necesarry changes in the Makefile, and you
can update the other buildsystems by regenerating the files. Keeping the
other buildsystems up-to-date with main development.
The generator system is designed to easily drop in pm's for other
buildsystems as well, if someone has an itch. However, the focus has been
Windows development, so the 'engine' might need patches to support any
platform.
Also add some .gitignore entries for MSVC files.

Based on original README patch from Frank Li, describe the steps
to build git with VS2008 (aka MSVC).
