191051c1e3 msvc: add No_SafeExceptionHandler option
Microsoft flipped the Windows Safe Exception Handling default
in VS2013 so that zlib became unacceptable to certain OS versions
(Vista and subsequent 32-bit OS's) without the addition of
the option -SAFESEH:NO.

Provide a switch to disable the Safe Exception Handler when required.

The option ImageHasSafeExceptionHandlers for VS2013 is not available in
earlier versions, so use the SAFESEH:NO linker flag. See
https://msdn.microsoft.com/en-us/library/9a89h429.aspx for
further details.

This has only had limited testing due to the lack of a suitable system.

5ab9a3499c contrib/buildsystems: make 'Restore NuGet Packages' work in Visual Studio
Visual Studio has this very neat feature that you can get dependencies in
the form of NuGet packages, and even further: you can specify in a project
what NuGet packages it needs. These dependencies can then be fetched via
right-clicking the solution in the Solution Explorer and clicking the
"Restore NuGet Packages" entry.

This feature is so neat, in fact, that we want to support it in Git for
Windows. The idea is that we will be able to provide developers with a
checkout of the Git sources that can be built outside of the Git for
Windows SDK, using *only* Visual Studio.

01be5c8573 contrib/buildsystems: support modern Visual Studio project definitions
The .sln/.vcproj files were used to define projects up until Visual
Studio 2008, but starting with Visual Studio 2010 the project
definitions are stored in .sln/.vcxproj files (which can also be used
by the MSBuild system).

Let's just copy-edit the generator of the .vcproj files to a new
generator that produces .vcxproj files directly, without forcing Visual
Studio to upgrade the project definitions.

93f61a3abc 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.

02897ceb88 t7800: fix quoting
When passing a command-line to call an external diff command to the

e.g. backslashes in the temporary directory's path on Windows.

This has been caught by running the test suite with an MSVC-built Git:
in contrast to the MINGW one, it does not rewrite `$TMP` to use forward
slashes instead of backslashes.

242bcd91a5 msvc: work around iconv() not setting errno
When compiling with MSVC, we rely on NuPkgs to provide the binaries of
dependencies such as libiconv. The libiconv 1.14.0.11 package available
from https://www.nuget.org/packages/libiconv seems to have a bug where
it does not set errno (when we would expect it to be E2BIG).

Let's simulate the error condition by taking less than 16 bytes
remaining in the out buffer as an indicator that we ran out of space.
While 16 might seem a bit excessive (when converting from, say, any
encoding to UTF-8, 8 bytes should be fine), it is designed to be a safe
margin.

042632aed1 msvc: fix isatty()
The hack that works in MINGW does not work with MSVC's CRT. Add MSVC
versions of isatty() and swap_osfhnd().

The MINGW versions attempt to replace the underlying OS HANDLE in an
existing file descriptor (fd) by writing to some undocumented fields in
the "ioinfo" structures inside the CRT. These structures changed size
and shape with the new UCRT in VS2015. The new MSVC versions of these
routines work without touching private fields. In theory, we should be
able to replace the ming versions with
this one.

2e49e3a2cd 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.

57fa061456 msvc: add NuGet scripts for building with VS2015
This commit contains a GNU Makefile and NuGet configuration scripts to
download and install the various third-party libraries that we will need
to build/link with when using VS2015 to build Git.

The file "compat/vcbuild/README_VS2015.txt" contains instructions for
using this.

In this commit, "compat/vcbuild/Makefile" contains hard-coded version
numbers of the packages we require.  These are set to the current
versions as of the time of this commit.  We use "nuget restore" to
install them explicitly using a "package.config".  A future improvement
would try to use some of the automatic package management functions and
eliminate the need to specify exact versions.  I tried, but could not
get this to work.  NuGet was happy dowload "minimum requirements" rather
than "lastest" for dependencies -- and only look at one package at a
time.  For example, both curl and openssl depend upon zlib and have
different minimums.  It was unclear which version of zlib would be
installed and seemed to be dependent on the order of the top-level
packages.  So, I'm skipping that for now.

We need to be very precise when specifying NuGet package versions: while
nuget.exe auto-completes a version, say, 1.0.2 to 1.0.2.0, we will want
to parse packages.config ourselves, to generate the Visual Studio
solution, and there we need the exact version number to be able to
generate the exact path to the correct .targets file.
