c751295cff 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.

effe4c7bec mingw: do resolve symlinks in getcwd()
As pointed out in https://github.com/git-for-windows/git/issues/1676,
the `git rev-parse --is-inside-work-tree` command currently fails when
the current directory's path contains symbolic links.

The underlying reason for this bug is that `getcwd()` is supposed to
resolve symbolic links, but our `mingw_getcwd()` implementation did not.

We do have all the building blocks for that, though: the
`GetFinalPathByHandleW()` function will resolve symbolic links. However,
we only called that function if `GetLongPathNameW()` failed, for
historical reasons: the latter function was supported for a long time,
but the former API function was introduced only with Windows Vista, and
we used to support also Windows XP. With that support having been
dropped, we are free to call the symbolic link-resolving function right
away.

122c561a00 mingw: make sure errno is set correctly when socket operations fail
The winsock2 library provides functions that work on different data
types than file descriptors, therefore we wrap them.

But that is not the only difference: they also do not set `errno` but
expect the callers to enquire about errors via `WSAGetLastError()`.

Let's translate that into appropriate `errno` values whenever the socket
operations fail so that Git's code base does not have to change its
expectations.

This closes https://github.com/git-for-windows/git/issues/2404

6142778233 Config option to disable side-band-64k for transport
Since commit 0c499ea60f the send-pack builtin uses the side-band-64k
capability if advertised by the server.

Unfortunately this breaks pushing over the dump git protocol if used
over a network connection.

The detailed reasons for this breakage are (by courtesy of Jeff Preshing,
quoted from ttps://groups.google.com/d/msg/msysgit/at8D7J-h7mw/eaLujILGUWoJ):
----------------------------------------------------------------------------
MinGW wraps Windows sockets in CRT file descriptors in order to mimic the
functionality of POSIX sockets. This causes msvcrt.dll to treat sockets as
Installable File System (IFS) handles, calling ReadFile, WriteFile,
DuplicateHandle and CloseHandle on them. This approach works well in simple
cases on recent versions of Windows, but does not support all usage patterns.
In particular, using this approach, any attempt to read & write concurrently
on the same socket (from one or more processes) will deadlock in a scenario
where the read waits for a response from the server which is only invoked after
the write. This is what send_pack currently attempts to do in the use_sideband
codepath.
----------------------------------------------------------------------------

The new config option "sendpack.sideband" allows to override the side-band-64k
capability of the server, and thus makes the dump git protocol work.

Other transportation methods like ssh and http/https still benefit from
the sideband channel, therefore the default value of "sendpack.sideband"
is still true.

a272ae37c1 config: normalize the path of the system gitconfig
Git for Windows is compiled with a runtime prefix, and that runtime
prefix is typically `C:/Program Files/Git/mingw64`. As we want the
system gitconfig to live in the sibling directory `etc`, we define the
relative path as `../etc/gitconfig`.

However, as reported by Philip Oakley, the output of `git config
--show-origin --system -l` looks rather ugly, as it shows the path as
`file:C:/Program Files/Git/mingw64/../etc/gitconfig`, i.e. with the
`mingw64/../` part.

By normalizing the path, we get a prettier path.

7f50b901ce cmake(windows): set correct path to the system Git config
Currently, when Git for Windows is built with CMake, the system Git config is
expected in a different location than when building via `make`: the former
expects it to be in `<runtime-prefix>/mingw64/etc/gitconfig`, the latter in
`<runtime-prefix>/etc/gitconfig`.

Because of this, things like `git clone` do not work correctly (because cURL is
no longer able to find its certificate bundle that it needs to validate HTTPS
certificates). See the full bug report and discussion here:
https://github.com/git-for-windows/git/issues/3071#issuecomment-789261386.

This commit aligns the CMake-based build by mimicking what is already done in
`config.mak.uname`.

95aae95c47 mingw: move Git for Windows' system config where users expect it
Git for Windows' prefix is `/mingw64/` (or `/mingw32/` for 32-bit
versions), therefore the system config is located at the clunky location
`C:\Program Files\Git\mingw64\etc\gitconfig`.

This moves the system config into a more logical location: the `mingw64`
part of `C:\Program Files\Git\mingw64\etc\gitconfig` never made sense,
as it is a mere implementation detail. Let's skip the `mingw64` part and
move this to `C:\Program Files\Git\etc\gitconfig`.

Side note: in the rare (and not recommended) case a user chooses to
install 32-bit Git for Windows on a 64-bit system, the path will of
course be `C:\Program Files (x86)\Git\etc\gitconfig`.

Background: During the Git for Windows v1.x days, the system config was
located at `C:\Program Files (x86)\Git\etc\gitconfig`. With Git for
Windows v2.x, it moved to `C:\Program Files\Git\mingw64\gitconfig` (or
`C:\Program Files (x86)\Git\mingw32\gitconfig`). Rather than fixing it
back then, we tried to introduce a "Windows-wide" config, but that never
caught on.

Likewise, we move the system `gitattributes` into the same directory.

Obviously, we are cautious to do this only for the known install
locations `/mingw64` and `/mingw32`; If anybody wants to override that
while building their version of Git (e.g. via `make prefix=$HOME`), we
leave the default location of the system config and gitattributes alone.

c0ba0524f8 clean: remove mount points when possible
Windows' equivalent to "bind mounts", NTFS junction points, can be
unlinked without affecting the mount target. This is clearly what users
expect to happen when they call `git clean -dfx` in a worktree that

target directory of said junction should be left alone (unless it is
inside the worktree).

d987fdecdd mingw: change core.fsyncObjectFiles = 1 by default
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.

0a6d6d58c0 clean: do not traverse mount points
It seems to be not exactly rare on Windows to install NTFS junction
points (the equivalent of "bind mounts" on Linux/Unix) in worktrees,
e.g. to map some development tools into a subdirectory.

In such a scenario, it is pretty horrible if `git clean -dfx` traverses
into the mapped directory and starts to "clean up".

Let's just not do that. Let's make sure before we traverse into a
directory that it is not a mount point (or junction).

fac75e863e gitk: prevent overly long command lines
To avoid running into command line limitations, some of Git's commands
support the `--stdin` option.

Let's use exactly this option in the three rev-list/log invocations in
gitk that would otherwise possibly run the danger of trying to invoke a
too-long command line.

While it is easy to redirect either stdin or stdout in Tcl/Tk scripts,
what we need here is both. We need to capture the output, yet we also
need to pipe in the revs/files arguments via stdin (because stdin does
not have any limit, unlike the command line). To help this, we use the
neat Tcl feature where you can capture stdout and at the same time feed
a fixed string as stdin to the spawned process.

One non-obvious aspect about this change is that the `--stdin` option
allows to specify revs, the double-dash, and files, but *no* other
options such as `--not`. This is addressed by prefixing the "negative"
revs with `^` explicitly rather than relying on the `--not` option
(thanks for coming up with that idea, Max!).

This fixes https://github.com/git-for-windows/git/issues/1987

07e6cbce2a archive: replace write_or_die() calls with write_block_or_die()
MinGit for Windows comes without `gzip` bundled inside, git-archive uses
`gzip -cn` to compress tar files but for this to work, gzip needs to be
present on the host system.

In the next commit, we will change the gzip compression so that we no
longer spawn `gzip` but let zlib perform the compression in the same
process instead.

In preparation for this, we consolidate all the block writes into a
single function.

6460159165 mingw: demonstrate a problem with certain absolute paths
On Windows, there are several categories of absolute paths. One such
category starts with a backslash and is implicitly relative to the
drive associated with the current working directory. Example:

	c:
	git clone https://github.com/git-for-windows/git \G4W

should clone into C:\G4W.

There is currently a problem with that, in that mingw_mktemp() does not
expect the _wmktemp() function to prefix the absolute path with the
drive prefix, and as a consequence, the resulting path does not fit into
the originally-passed string buffer. The symptom is a "Result too large"
error.
