9fb58ef5af Vcproj.pm: list git.exe first to be startup project
Visual Studio takes the first listed application/library as the default
startup project [1].

Detect the 'git' project and place it the head of the apps list, rather
than the tail.

Export the apps list before libs list for both the projects and global
structures of the .sln file.

    "In the solution file, there are a list of pseudo-XML "Project"
    entries. It turns out that whatever is the first one ends up as
    the Startup Project, unless it’s overridden in the suo file. Argh.
    I just rearranged the order in the file and it’s good."

    "just moving the pseudo-xml isn't enough. You also have to move the
    group of entries in the "GlobalSection(ProjectConfigurationPlatforms)

    the top. So there are two places to move lines."

2deac74906 Vcproj.pm: auto-generate GUIDs
We ran out GUIDs. Again. But there is no need to: we can generate them
semi-randomly from the target file name of the project.

Note: the Vcproj generator is probably only interesting for historical
reasons; nevertheless, the upcoming Vcxproj generator (to support modern
Visual Studio versions) is based on the Vcproj generator and it is
better to fix this here first.

b71a7ab3b8 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).

b29b694c46 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.

3cd229795f 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.

dfaee9d74b 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().

a3d62ba5ca Merge 'builtin-rebase--am'
This patch teaches the builtin rebase to avoid the scripted --am backend
and call `git format-patch` and `git am` directly.

Meaning: apart from the --merge and the --preserve-merges backends, `git
rebase` is now implemented in pure C, with no need to ask the Unix shell
interpreter for help.

This brings us really close to a fully builtin `git rebase`: the
--preserve-merges mode is about to be deprecated (as soon as the
--rebase-merges mode has proven stable and robust enough), and there are
plans to scrap the `git-rebase--merge` backend in favor of teaching the
interactive rebase enough tricks to run the --merge mode, too.

9f27fe313c Merge branch 'mingw-expand-absolute-user-path'
When compiling Git with a runtime prefix (so that it can be installed
into any location, finding its libexec/ directory relative to the
location of the `git` executable), it is convenient to provide
"absolute" Unix-y paths e.g. for http.sslCAInfo, and have those absolute
paths be resolved relative to the runtime prefix.

This patch makes it so for Windows. It is up for discussion whether we
want this for other platforms, too, as long as building with
RUNTIME_PREFIX.

dd96399fd6 Merge branch 'test-git-installed'
This patch series contains a couple of fixes revolving around testing
an installed Git, via GIT_TEST_INSTALLED=/path/to/git.

The original motivation for these patches is that Git for Windows wants
to provide a version where the Unix shell scripts are interpreted by
BusyBox (to reduce the footprint on disk, mainly), and we want to verify
that this actually works, and is not perchance missing any Unix shell
tool that is present in the Git for Windows SDK but is missing from the
installed set of files.

While the BusyBox-based Git for Windows is not ready for prime time,
this here patch series is, and might be useful for packagers who want to
verify a similar scenario.

b65863f218 Merge branch 'unc-path-w-backslashes'
This topic branch addresses a problem identified in
https://github.com/git-for-windows/git/issues/439: while
cloning/fetching/pushing from "POSIX-ified UNC paths" (i.e. UNC paths
whose backslashes have been converted to forward slashes) works for some
time now, true UNC paths (with backslashes left intact) were handled
incorrectly. Example:

	git clone //myserver/folder/repo.git

works, but

	git clone \\myserver\folder\repo.git

(in CMD; in Git Bash, the backslashes would need to be doubled) used to
fail. The reason was an unexpected difference in command-line handling
between Win32 executables and MSYS2 ones (such as the shell that is used
by git-clone.exe to spawn git-upload-pack.exe).

This topic branch features a workaround *just* for the case where Git
passes stuff through sh.exe (which covers quite a few use cases,
though).

42c6914129 diff: ensure correct lifetime of external_diff_cmd
According to getenv(3)'s notes:

    The implementation of getenv() is not required to be reentrant.  The
    string pointed to by the return value of getenv() may be statically
    allocated, and can be modified by a subsequent call to getenv(),
    putenv(3), setenv(3), or unsetenv(3).

Since strings returned by getenv() are allowed to change on subsequent
calls to getenv(), make sure to duplicate when caching external_diff_cmd
from environment.

This problem becomes apparent on Git for Windows since fe21c6b285
(mingw: reencode environment variables on the fly (UTF-16 <-> UTF-8)),
when the getenv() implementation provided in compat/mingw.c was changed
to keep a certain amount of alloc'ed strings and freeing them on
subsequent calls.

This fixes https://github.com/git-for-windows/git/issues/2007:

ebada47d88 .gitattributes: ensure t/oid-info/* has eol=lf
The new test_oid machinery in the test library requires reading
some information from t/oid-info/hash-info and t/oid-info/oid.
The shell logic that reads from these files is sensitive to CRLF
line endings, causing a failure when the test suite is run on a
Windows machine that converts LF to CRLF: the test suite fails
with a "bad hash algorithm" message, but does not record any
failed test cases. This caused CI builds to pass because they
fail only after reporting the failed test cases.

4912066ec8 built-in rebase: call git am directly
While the scripted `git rebase` still has to rely on the
`git-rebase--am.sh` script to implement the glue between the `rebase`
and the `am` commands, we can go a more direct route in the built-in
rebase and avoid using a shell script altogether.

This patch represents a straight-forward port of `git-rebase--am.sh` to
C, along with the glue code to call it directly from within
`builtin/rebase.c`.

This reduces the chances of Git for Windows running into trouble due to
problems with the POSIX emulation layer (known as "MSYS2 runtime",
itself a derivative of the Cygwin runtime): when no shell script is
called, the POSIX emulation layer is avoided altogether.

Note: we pass an empty action to `reset_head()` here when moving back to
the original branch, as no other action is applicable, really. This
parameter is used to initialize `unpack_trees()`' messages.
