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

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.

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

With the recent changes to allow building with MSVC=1, we now pass the

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.

When passing a command-line to call an external diff command to the
difftool, we must be prepared for paths containing special characters,
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.

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.

The MINGW version of the main() wrapper gets away with declaring symbols
that were intentionally not exported. However, some of these symbols do
not actually exist in MSVC's UCRT.
So let's add an MSVC version of the main() wrapper that uses wmain() and
imports the UNICODE argv and environment. While at it, we pass our UTF-8
version of ARGV to the real main -- rather than overwriting __argv as is
done in the MINGW Version.

This adds MSVC versions of getenv() and friends. These take UTF-8
arguments and return UTF-8 values, but use the UNICODE versions

also avoids the CP_ACP conversions performed inside the CRT.

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.

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.

stat() should always return the statistics of the file or directory a
symbolic link is pointing to. The lstat() function is used to get the
stats for the symlink. Hence the check should not be there.
