Add the infrastructure to iterate over a `packed_ref_store`. It's a
lot of boilerplate, but it's all part of a campaign to make
`packed_ref_store` implement `ref_store`. In the future, this iterator

These changes are necessary to support better Git for Windows' new

Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de>
"Question?" is maybe not the most informative thing to ask. In the
absence of better information, it is the best we can do, of course.
However, Git for Windows' auto updater just learned the trick to use
git-gui--askyesno to ask the user whether to update now or not. And in
this scripted scenario, we can easily pass a command-line option to
change the window title.
So let's support that with the new `--title <title>` option.

Add .LIBs for zlib and openssl to <AdditionalDependencies>

This closes https://github.com/git-for-windows/git/issues/1234
Note: this patch still leaves a couple of TODOs:
- It should be possible to add GEN.DEPS\lib to
<AdditionalLibraryDependencies> and then just set
<AdditionalDependencies> to the library basenames.
- Likewise, you should be able to copy GEN.DEPS\bin\*.dll
to the destination directory rather than using the full
paths in the $afterTargets lines.
(This is in line with items in <AdditionalIncludeDirectories>
referencing GEN.DEPS\include.)

We run `git rev-parse` though the shell, and quote its

The git-cvsserver script is old and largely unmaintained
these days. But git-shell allows untrusted users to run it
out of the box, significantly increasing its attack surface.
Let's drop it from git-shell's list of internal handlers so
that it cannot be run by default. This is not backwards
compatible. But given the age and development activity on
CVS-related parts of Git, this is likely to impact very few
users, while helping many more (i.e., anybody who runs
git-shell and had no intention of supporting CVS).
There's no configuration mechanism in git-shell for us to
add a boolean and flip it to "off". But there is a mechanism
for adding custom commands, and adding CVS support here is
fairly trivial. Let's document it to give guidance to
anybody who really is still running cvsserver.

From the documentation of said setting:
This boolean will enable fsync() when writing object files.
This is a total waste of time and effort on a filesystem that
orders data writes properly, but can be useful for filesystems
that do not use journalling (traditional UNIX filesystems) or
that only journal metadata and not file contents (OS X’s HFS+,
or Linux ext3 with "data=writeback").
The most common file system on Windows (NTFS) does not guarantee that
order, therefore a sudden loss of power (or any other event causing an
unclean shutdown) would cause corrupt files (i.e. files filled with
NULs). Therefore we need to change the default.
Note that the documentation makes it sound as if this causes really bad
performance. In reality, writing loose objects is something that is done
only rarely, and only a handful of files at a time.

Git for Windows supports the core.longPaths config setting to allow
writing/reading long paths via the \\?\ trick for a long time now.
However, for that support to work, it is absolutely necessary that
git_default_config() is given a chance to parse the config. Otherwise
Git will be non the wiser.
So let's make sure that as many commands that previously failed to
parse the core.* settings now do that, implicitly enabling long path
support in a lot more places.
Note: this is not a perfect solution, and it cannot be, as there is
a chicken-and-egg problem in reading the config itself...

A regression was introduced into Git for Windows v2.13.* via a
half-finished refactoring of the refs handling. This refactoring has
been completed in the meantime, but is was only merged into upstream's
`master` branch, i.e. it was not integrated into the maintenance track.
Git for Windows is used quite a bit in enterprise settings, though,
where a large number of refs is quite common, and therefore the
regression really hurts.
So let's take this regression fix earlier than upstream Git.

A ton of Git commands simply do not read (or at least parse) the core.*
settings. This is not good, as Git for Windows relies on the
core.longPaths setting to be read quite early on.
So let's just make sure that all commands read the config and give
platform_core_config() a chance.
This patch teaches tons of Git commands to respect the config setting
`core.longPaths = true`, including `pack-refs`, thereby fixing

Teach the top-level git Makefile to use whatever VS compiler
tool chain is installed on the system.
When building git from the command line in a git-sdk BASH
window with MAKE, the shell environment has environment
variables for GCC tools, but not MSVC tools. MSVC bindings
are only avaliable from the various "VcVarsAll.bat" scripts
run by the "Developer Command Prompt" shortcuts.
Add compat/vcbuild/find_vs_env.bat to the Makefile. It
uses the various "VcVarsAll.bat" scripts in a background
Developer Command Prompt process to compute the proper
environment variables and publish them for use by the Makefile.
