This fixes the compilation, actually, as we still did not make the jump to
post-Windows XP completely: we still compile with _WIN32_WINNT set to
0x0502 (which corresponds to Windows Server 2003 and is technically
greater than Windows XP's 0x0501).
However, GetTickCount64() is only available starting with Windows
Vista/Windows Server 2008.
Let's just lazy-load the function, which should also help Git for Windows
contributors who want to reinstate Windows XP support.

For a short while, we had two tracks: the `master` one, based on
v2.19.2, and the `rebase-to-v2.20.0-rc<N>` one, following the -rc
versions of v2.20.0.
Since we forward-ported all changes from `master` to the -rc track (or
backported them in the other direction), at this point we have all of
`origin/master` already, and can continue the merging rebase to v2.20.0
based on the `rebase-to-v2.20.0-rc<N>` track (which has a lot of the
merge conflicts resolved already).
So let's just merge in the commit history of `master`, without changing
the tree (i.e. with `-s ours`, just like the fake merge starting the
merging rebase). That way, the new `master` will fast-forward from the
old `master`.

Usually we don't need to set libcurl to choose which version of the
HTTP protocol to use to communicate with a server.
But different versions of libcurl, the default value is not the same.
CURL >= 7.62.0: CURL_HTTP_VERSION_2TLS
CURL < 7.62: CURL_HTTP_VERSION_1_1
In order to give users the freedom to control the HTTP version,
we need to add a setting to choose which HTTP version to use.

This fixes the reflog messages, as expected by t3406 in v2.20.0-rc2, as
well as fixing a compiler warning about "" being an invalid

The text body of section Behavioral Differences is typeset as code,
but should be regular text. Remove the indentation to achieve that.
While here, prettify the language:
- use "the x backend" instead of "x-based rebase";
- use present tense instead of future tense;
and use subsections instead of a list.

Commit d8981c3f88 ("format-patch: do not let its diff-options affect
--range-diff", 2018-11-30) taught `show_range_diff()` to accept a
NULL-pointer as an indication that it should use its own "reasonable
default". That fixed a regression from a5170794 ("Merge branch
'ab/range-diff-no-patch'", 2018-11-18), but unfortunately it introduced
a regression of its own.
In particular, it means we forget the `file` member of the diff options,
so rather than placing a range-diff in the cover-letter, we write it to
stdout. In order to fix this, rewrite the two callers adjusted by
d8981c3f88 to instead create a "dummy" set of diff options where they
only fill in the fields we absolutely require, such as output file and
color.
Modify and extend the existing tests to try and verify that the right
contents end up in the right place.
Don't revert `show_range_diff()`, i.e., let it keep accepting NULL.
Rather than removing what is dead code and figuring out it isn't
actually dead and we've broken 2.20, just leave it for now.
[es: retain diff coloring when going to stdout]

For many Win32 functions, there actually exist two variants: one with
the `A` suffix that takes ANSI parameters (`char *` or `const char *`)
and one with the `W` suffix that takes Unicode parameters (`wchar_t *`
or `const wchar_t *`).
Let's be precise what we want to use.

We cannot rely on `uname -m` in Git for Windows' SDK to tell us what
architecture we are compiling for, as we can compile both 32-bit and
64-bit `git.exe` from a 64-bit SDK, but the `uname -m` in that SDK will
always report `x86_64`.
So let's go back to our original design. And make it explicitly
Windows-specific.

Using FindFirstFileExW() requires the OS to allocate a 64K buffer for each
directory and then free it when we call FindClose(). Update fscache to call
the underlying kernel API NtQueryDirectoryFile so that we can do the buffer
management ourselves. That allows us to allocate a single buffer for the
lifetime of the cache and reuse it for each directory.
This change improves performance of 'git status' by 18% in a repo with ~200K
files and 30k folders.
Documentation for NtQueryDirectoryFile can be found at:
https://docs.microsoft.com/en-us/windows-hardware/drivers/ddi/content/ntifs/nf-ntifs-ntquerydirectoryfilehttps://docs.microsoft.com/en-us/windows/desktop/FileIO/file-attribute-constantshttps://docs.microsoft.com/en-us/windows/desktop/fileio/reparse-point-tags
To determine if the specified directory is a symbolic link, inspect the
FileAttributes member to see if the FILE_ATTRIBUTE_REPARSE_POINT flag is
set. If so, EaSize will contain the reparse tag (this is a so far
undocumented feature, but confirmed by the NTFS developers). To
determine if the reparse point is a symbolic link (and not some other
form of reparse point), test whether the tag value equals the value
IO_REPARSE_TAG_SYMLINK.

To support IPv6, Git provided fall back functions for Windows versions that
did not support IPv6. However, as Git dropped support for Windows XP and
prior, those functions are not needed anymore.
Removed those fallbacks by reverting commit[1] and using the functions
directly (without 'ipv6_' prefix).

When debugging Git, the criss-cross spawning of processes can make
things quite a bit difficult, especially when a Unix shell script is
thrown in the mix that calls a `git.exe` that then segfaults.
To help debugging such things, we introduce the `open_in_gdb()` function
which can be called at a code location where the segfault happens (or as
close as one can get); This will open a new MinTTY window with a GDB
that already attached to the current process.
