Add a new 'bitmap' test-tool which can be used to list the commits that
have received bitmaps.
In theory, a determined tester could run 'git rev-list --test-bitmap
<commit>' to check if '<commit>' received a bitmap or not, since
'--test-bitmap' exits with a non-zero code when it can't find the
requested commit.
But this is a dubious behavior to rely on, since arguably 'git
rev-list' could continue its object walk outside of which commits are
covered by bitmaps.
This will be used to test the behavior of 'pack.preferBitmapTips', which
will be added in the following patch.

The next patch will add a 'bitmap' test-tool which prints the list of
commits that have bitmaps computed.
The test helper could implement this itself, but it would need access to
the 'bitmaps' field of the 'pack_bitmap' struct. To avoid exposing this
private detail, implement the entirety of the helper behind a
test_bitmap_commits() function in pack-bitmap.c.
There is some precedence for this with test_bitmap_walk() which is used
to implement the '--test-bitmap' flag in 'git rev-list' (and is also
implemented in pack-bitmap.c).
A caller will be added in the next patch.

save_opts() should save any non-default values. It was intended to do
this, but since most options in struct replay_opts default to 0, it only
saved non-zero values. Unfortunately, this does not always work for
options.edit. Roughly speaking, options.edit had a default value of 0
for cherry-pick but a default value of 1 for revert. Make save_opts()
record a value whenever it differs from the default.
options.edit was also overly simplistic; we had more than two cases.
The behavior that previously existed was as follows:
Non-conflict commits Right after Conflict
revert Edit iff isatty(0) Edit (ignore isatty(0))
cherry-pick No edit See above
Specify --edit Edit (ignore isatty(0)) See above
Specify --no-edit (*) See above
(*) Before stopping for conflicts, No edit is the behavior. After
stopping for conflicts, the --no-edit flag is not saved so see
the first two rows.
However, the expected behavior is:
Non-conflict commits Right after Conflict
revert Edit iff isatty(0) Edit iff isatty(0)
cherry-pick No edit Edit iff isatty(0)
Specify --edit Edit (ignore isatty(0)) Edit (ignore isatty(0))
Specify --no-edit No edit No edit
In order to get the expected behavior, we need to change options.edit
to a tri-state: unspecified, false, or true. When specified, we follow
what it says. When unspecified, we need to check whether the current
commit being created is resolving a conflict as well as consulting
options.action and isatty(0). While at it, add a should_edit() utility
function that compresses options.edit down to a boolean based on the
additional information for the non-conflict case.
continue_single_pick() is the function responsible for resuming after
conflict cases, regardless of whether there is one commit being picked
or many. Make this function stop assuming edit behavior in all cases,
so that it can correctly handle !isatty(0) and specific requests to not
edit the commit message.

Handle sub-commands of the 'git multi-pack-index' builtin (e.g.,
"write", "repack", etc.) separately from one another. This allows
sub-commands with unique options, without forcing cmd_multi_pack_index()
to reject invalid combinations itself.
This comes at the cost of some duplication and boilerplate. Luckily, the
duplication is reduced to a minimum, since common options are shared
among sub-commands due to a suggestion by Ævar. (Sub-commands do have to
retain the common options, too, since this builtin accepts common
options on either side of the sub-command).
Roughly speaking, cmd_multi_pack_index() parses options (including
common ones), and stops at the first non-option, which is the
sub-command. It then dispatches to the appropriate sub-command, which
parses the remaining options (also including common options).
Unknown options are kept by the sub-commands in order to detect their
presence (and complain that too many arguments were given).

Right now, options and flags are handled separately. That's fine, since
the options structure is never passed around. But a future patch will
make it so that common options shared by all sub-commands are defined in

Our CMake configuration generates not only build definitions, but also
install definitions: After building Git using `msbuild git.sln`, the
built artifacts can be installed via `msbuild INSTALL.vcxproj`.
To specify _where_ the files should be installed, the
`-DCMAKE_INSTALL_PREFIX=<path>` option can be used when running CMake.
However, this process would really only install the files that were just
built. On Windows, we need more than that: We also need the `.dll` files
of the dependencies (such as libcurl). The `vcpkg` ecosystem, which we
use to obtain those dependencies, can be asked to install said `.dll`
files really easily, so let's do that.
This requires more than just the built `vcpkg` artifacts in the CI build
definition; We now clone the `vcpkg` repository so that the relevant
CMake scripts are available, in particular the ones related to defining
the toolchain.

We are about to add support for installing the `.dll` files of Git's
dependencies (such as libcurl) in the CMake configuration. The `vcpkg`
ecosystem from which we get said dependencies makes that relatively
easy: simply turn on `X_VCPKG_APPLOCAL_DEPS_INSTALL`.
However, current `vcpkg` introduces a limitation if one does that:
While it is totally cool with CMake to specify multiple targets within
one invocation of `install(TARGETS ...) (at least according to
https://cmake.org/cmake/help/latest/command/install.html#command:install),
`vcpkg`'s parser insists on a single target per `install(TARGETS ...)`
invocation.
Well, that's easily accomplished: Let's feed the targets individually to
the `install(TARGETS ...)` function in a `foreach()` look.
This also has the advantage that we do not have to manually cull off the
two entries from the `${PROGRAMS_BUILT}` array before scheduling the
remainder to be installed into `libexec/git-core`. Instead, we iterate
through the array and decide for each entry where it wants to go.

Passing the msg_type is now redundant, as you can always get it back

Untangling that would take some more work, since we expose the new

But that's OK in this case, reporting this fsck issue to the user
isn't performance-sensitive. If we were somehow doing so in a tight
