bde6cec066 bin-wrappers: append .exe to target paths if necessary
When compiling with Visual Studio, the projects' names are identical to
the executables modulo the extensions. Read: there will exist both a
directory called `git` as well as an executable called `git.exe` in the
end. Which means that the bin-wrappers *need* to target the `.exe` files
lest they try to execute directories.

3920b92343 vcxproj: also link-or-copy builtins
The problem with not having, say, git-receive-pack.exe after a full
build is that the test suite will then happily use the *installed*
git-receive-pack.exe because it finds nothing else.

Absolutely not what we want. We want to have confidence that our test
covers the MSVC-built Git executables, and not some random stuff.

93c0456644 msvc: add a Makefile target to pre-generate the VS solution
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.

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 (that is part of a regular Git for Windows installation) after
building the solution in Visual Studio.

a9e322b699 contrib/buildsystems: add a backend for modern Visual Studio versions
Based on the previous patch series to be able to compile Git using
Visual C++ from the command-line, this patch offers to generate project
definitions for Visual Studio, so that Git can be developed in a modern
IDE.

Based on the generator for Visual Studio versions <= 2008 (which used
.sln/.vcproj files), this patch copy-edits the generator of the .vcproj
files to a new generator that produces .vcxproj files ready for Visual
Studio 2010 and later (or MSBuild).

As the vcpkg system (which is used to build Git's dependencies) cannot
run in parallel (it does not lock, wreaking havoc with files being
accessed and written at the same time, letting the vcpkg processes
stumble over each others' toes), we make libgit the root of the project
dependency tree and initialize the vcpkg system in this project's
PreBuildEvent.

One time too many did this developer call the `generate` script passing

c078b82ea0 contrib/buildsystems: handle options starting with a slash
With the recent changes to allow building with MSVC=1, we now pass the

704cae2865 contrib/buildsystems: redirect errors of the dry run into a log file
Rather than swallowing the errors, it is better to have them in a file.

To make it obvious what this is about, use the file name
'msvc-build-makedryerrors.txt'.

Further, if the output is empty, simply delete that file. As we target
Git for Windows' SDK (which, unlike its predecessor msysGit, offers Perl
versions newer than 5.8), we can use the quite readable syntax `if -f -z
$ErrsFile` (available in Perl >=5.10).

Note that the file will contain the new values of the GIT_VERSION and
GITGUI_VERSION if they were generated by the make file. They are omitted
if the release is tagged and indentically defined in their respective
GIT_VERSION_GEN file DEF_VER variables.

9b4a053078 contrib/buildsystems: ignore invalidcontinue.obj
Since 4b623d8 (MSVC: link in invalidcontinue.obj for better POSIX
compatibility, 2014-03-29), invalidcontinue.obj is linked in the MSVC
build, but it was not parsed correctly by the buildsystem. Ignore it, as
it is known to Visual Studio and will be handled elsewhere.

Also only substitute filenames ending with .o when generating the
source .c filename, otherwise we would start to expect .cbj files to
generate .obj files (which are not generated by our build)...

In the future there may be source files that produce .obj files
so keep the two issues (.obj files with & without source files)
separate.

6b5b1687fe msvc: avoid debug assertion windows in Debug Mode
For regular debugging, it is pretty helpful when a debug assertion in a
running application triggers a window that offers to start the debugger.

However, when running the test suite, it is not so helpful, in
particular when the debug assertions are then suppressed anyway because
we disable the invalid parameter checking (via invalidcontinue.obj, see
the comment in config.mak.uname about that object for more information).

So let's simply disable that window in Debug Mode (it is already
disabled in Release Mode).

266352cec9 msvc: support building Git using MS Visual C++
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 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.

202e83a23d msvc: define O_ACCMODE
This constant is not defined in MSVC's headers.

In UCRT's fcntl.h, _O_RDONLY, _O_WRONLY and _O_RDWR are defined as 0, 1
and 2, respectively. Yes, that means that UCRT breaks with the tradition
that O_RDWR == O_RDONLY | O_WRONLY.

It is a perfectly legal way to define those constants, though, therefore
we need to take care of defining O_ACCMODE accordingly.

This is particularly important in order to keep our "open() can set
errno to EISDIR" emulation working: it tests that (flags & O_ACCMODE) is
not identical to O_RDONLY before going on to test specifically whether
the file for which open() reported EACCES is, in fact, a directory.

c00fd085d7 mingw: replace mingw_startup() hack
Git for Windows has special code to retrieve the command-line parameters
(and even the environment) in UTF-16 encoding, so that they can be
converted to UTF-8. This is necessary because Git for Windows wants to
use UTF-8 encoded strings throughout its code, and the main() function
does not get the parameters in that encoding.

To do that, we used the __wgetmainargs() function, which is not even a
Win32 API function, but provided by the MINGW "runtime" instead.

Obviously, this method would not work with any other compiler than GCC,
and in preparation for compiling with Visual C++, we would like to avoid
that.

Lucky us, there is a much more elegant way: we simply implement wmain()
and link with -municode. The command-line parameters are passed to
wmain() encoded in UTF-16, as desired, and this method also works with
Visual C++ after adjusting the MSVC linker flags to force it to use
wmain().
