57361dec63 mingw: Make sure sigset_t is defined
With MSys2, the sigset_t type is defined in sys/types.h, therefore we
need to #include said file.

66ffa61117 MSys2: Fix t9700 assumption about directory separators
This test assumed that there are no two equivalent directory separators.
However, on Windows, the back slash and the forward slash *are*
equivalent. Let's paper over this issue by converting the backward
slashes to forward ones in the test that fails with MSys2 otherwise.

67a9becb63 Tests: optionally skip redirecting stdin/stdout/stderr
There is a really useful debugging technique developed by Sverre
Rabbelier that inserts "bash &&" somewhere in the test scripts, letting
the developer interact at given points with the current state.

Another debugging technique, used a lot by this here coder, is to run
certain executables via gdb by guarding a "gdb -args" call in
bin-wrappers/git.

Both techniques were disabled by 781f76b1(test-lib: redirect stdin of
tests).

Let's reinstate the ability to run an interactive shell by making the
redirection optional: setting the TEST_NO_REDIRECT environment variable
will skip the redirection.

4821adde9f Tests (MinGW): Disable mkfifo-based tests
With MSys2, there is actually an implementation of mkfifo available. The
only problem is that it is only emulating named pipes through the MSys2
runtime; The Win32 API has no idea about named pipes, hence the Git
executable cannot access those pipes either.

The symptom is that Git fails with a '<name>: No such file or directory'
because MSys2 emulates named pipes through special-crafted '.lnk' files.

The solution is to tell the test suite explicitly that we cannot use
named pipes when we want to test a MinGW Git.

2d0cab3bbd Tests (MinGW): Do not bother to test funny file names
MSys2 actually allows to create files or directories whose names contain
tabs, newlines or colors, even if plain Win32 API cannot access them.
As we are using an MSys2 bash to run the tests, such files or
directories are created successfully, but Git has no chance to work with
them because it is a regular Windows program, hence limited by the Win32
API.

709e592c6e Special-case the MSYS2_TZ environment variable
With MSys2, the "TZ" environment variable gets filtered out when calling
non-MSys2 executables. The reason is that Windows' time zone handling is
substantially different from the POSIX one.

However, we just taught Git for Windows' fork of the MSys2 runtime to
pass on the timezone in a different environment variable, MSYS2_TZ for
the sole purpose of Git being able to reinterpret it correctly.

0982918d50 config.mak.uname: support MSys2
Git for Windows lags a little bit behind with the 2.x releases because
the Git for Windows developers wanted to let that big jump coincide with
a well-needed overhaul of the context within which Git for Windows is
developed.

To understand why this is such a big issue, it needs to be noted that
many parts of Git are not written in portable C, but instead relies on a
POSIX shell and Perl to be available. Even in the portable C part, there
is the ingrained notion that we can work with UTF-8 encoded strings.

To support the scripts, Git for Windows has to ship a minimal POSIX
emulation layer with Bash and Perl thrown in, and when the Git for
Windows effort started originally, in August 2007, we settled on using
MSys, a stripped down version of Cygwin. Consequently, the original name
of the project was "msysGit" (which, sadly, caused a *lot* of confusion
because few Windows users know about MSys, and even less care).

To compile the C code of Git for Windows, we used MSys, too: it sports
an additional version of the GNU C Compiler that targets the plain
Win32 API (with a few convenience functions thrown in) instead of the
POSIX emulation layer that would require the MSys runtime to run the
compiled programs. That way, Git for Windows' executable(s) are really
just Win32 programs. To discern executables requiring the POSIX
emulation layer from the ones that do not, the latter are called MinGW
(Minimal GNU for Windows) when the former are called MSys executables.

This reliance on MSys incurred challenges, too, though: some of our
changes to the MSys runtime -- necessary to support Git for Windows
better -- were not accepted upstream, the MSys runtime was not developed
further to support e.g. UTF-8 or 64-bit, and apart from not having a
package management system until much later (when mingw-get was
introduced), many packages provided by the MSys/MinGW project lag behind
the respective source code versions, in particular Bash and OpenSSL. For
a while, the Git for Windows project tried to remedy the situation by
trying to build newer versions of those packages, but the situation
quickly became untenable, especially with problems like the Heartbleed
bug requiring swift action and Git for Windows contributors being scarce
-- despite millions of downloads suggesting that there are many users.

After a brief push in the direction of mingw-get, thanks to the
long-time contributor and co-maintainer Sebastian Schuberth, it became
clear that we need to look for alternatives.

Happily, in the meantime the MSys2 project (https://msys2.github.io/)
emerged, and was chosen to be the base of the Git for Windows 2.x. MSys2
is a rewrite of the spirit of MSys: it is again a stripped down version
of Cygwin, but it is actively kept up-to-date with Cygwin's source code.
Thereby, it already supports Unicode internally, and it also offers the
64-bit support that we yearned for since the beginning of the Git for
Windows project.

MSys2 also ported the Pacman package management system from Arch Linux
and uses it heavily. This brings the same convenience to which Linux
users are used to from `yum` or `apt-get`, and to which MacOSX users are
used to from Homebrew or MacPorts, or BSD users from the Ports system,
to MSys2: a simple `pacman -Syu` will update all installed packages to
the newest versions currently available.

MSys2 is also *very* active, typically providing package updates
multiple times per week.

It still required a two-month effort to bring everything to a state
where Git's test suite passes, and a couple of patches await their
submission to the respective upstream projects. Yet without MSys2, the
modernization of Git for Windows would simply not have happened.

This commit lays the ground work to supporting MSys2-based Git builds.

a5849e8a30 Handle http.* config variables pointing to files gracefully on Windows
On Windows, we would like to be able to have a default http.sslCAinfo
that points to an MSys path (i.e. relative to the installation root of
Git).  As Git is a MinGW program, it has to handle the conversion
of the MSys path into a MinGW32 path itself.

Since system_path() considers paths starting with '/' as absolute, we
have to convince it to make a Windows path by stripping the leading
slash.

One use case for such empty credentials is with NTLM authentication, where

When locating the relevant credentials, make empty username match null.

59179074be Work around the command line limit on Windows
On Windows, there are dramatic problems when a command line grows
beyond PATH_MAX, which is restricted to 8191 characters on XP and
later (according to http://support.microsoft.com/kb/830473).

Work around this by just cutting off the command line at that length
(actually, at a space boundary) in the hope that only negative
refs are chucked: gitk will then do unnecessary work, but that is
still better than flashing the gitk window and exiting with exit
status 5 (which no Windows user is able to make sense of).

The first fix caused Tcl to fail to compile the regexp, see msysGit issue
427. Here is another fix without using regexp, and using a more relaxed
command line length limit to fix the original issue 387.

255007634f Windows: use %PROGRAMDATA%\Git\config as Windows-wide configuration
Between the libgit2 and the Git for Windows project, there has been a
discussion how we could share Git configuration to avoid duplication (or
worse: skew).

Earlier, libgit2 was nice enough to just re-use Git for Windows'

	C:\Program Files (x86)\Git\etc\gitconfig

but with the upcoming Git for Windows 2.x, there would be more paths to
search, as we will have 64-bit and 32-bit versions, and the
corresponding config files will be in %PROGRAMFILES%\Git\mingw64\etc and
...\mingw32\etc, respectively.

Therefore we came to a consensus to use %PROGRAMDATA%\Git as the
location for Git-specific files that are of wider interest than just Git
for Windows.
