Commit 01d3a526ad (t0000: check whether the shell supports the "local"

The stream of symbols that makes up this function is hard for humans
to follow, too. The complexity mostly comes from the repeated use of
the expression ${1#??} for the basename of the loose object. Use a
variable instead --- nowadays, the dialect of shell used by Git
permits local variables, so this is cheap.
An alternative way to work around [*] is to remove the double-quotes
around test_oid_to_path's return value. That makes the expression
easier for dash to read, but harder for humans. Let's prefer the
rephrasing that's helpful for humans, too.
Noticed by building on Ubuntu trusty, which uses dash 0.5.7.

merge-recursive: avoid directory rename detection in recursive case
Ever since commit 8c8e5bd6eb33 ("merge-recursive: switch directory
rename detection default", 2019-04-05), the default handling with
directory rename detection was to report a conflict and leave unstaged
entries in the index. However, when creating a virtual merge base in
the recursive case, we absolutely need a tree, and the only way a tree
can be written is if we have no unstaged entries -- otherwise we hit a
BUG().
There are a few fixes possible here which at least fix the BUG(), but
none of them seem optimal for other reasons; see the comments with the
new testcase 13e in t6043 for details (which testcase triggered a BUG()
prior to this patch). As such, just opt for a very conservative and
simple choice that is still relatively reasonable: have the recursive
case treat 'conflict' as 'false' for opt->detect_directory_renames.

In 1771be90 "commit-graph: merge commit-graph chains" (2019-06-18),
the method sort_and_scan_merged_commits() was added to merge the
commit lists of two commit-graph files in the incremental format.
Unfortunately, there was an off-by-one error in that method around
incrementing num_extra_edges, which leads to an incorrect offset
for the base graph chunk.
When we store an octopus merge in the commit-graph file, we store
the first parent in the normal place, but use the second parent
position to point into the "extra edges" chunk where the remaining
parents exist. This means we should be adding "num_parents - 1"
edges to this list, not "num_parents - 2". That is the basic error.
The reason this was not caught in the test suite is more subtle.
In 5324-split-commit-graph.sh, we test creating an octopus merge
and adding it to the tip of a commit-graph chain, then verify the
result. This _should_ have caught the problem, except that when
we load the commit-graph files we were overly careful to not fail
when the commit-graph chain does not match. This care was on
purpose to avoid race conditions as one process reads the chain
and another process modifies it. In such a case, the reading
process outputs the following message to stderr:
warning: commit-graph chain does not match
These warnings are output in the test suite, but ignored. By
checking the stderr of `git commit-graph verify` to include
the expected progress output, it will now catch this error.

config: work around bug with includeif:onbranch and early config
Since 07b2c0eacac (config: learn the "onbranch:" includeIf condition,
2019-06-05), there is a potential catch-22 in the early config path: if
the `include.onbranch:` feature is used, Git assumes that the Git
directory has been initialized already. However, in the early config
code path that is not true.
One way to trigger this is to call the following commands in any
repository:
git config includeif.onbranch:refs/heads/master.path broken
git help -a
The symptom triggered by the `git help -a` invocation reads like this:
BUG: refs.c:1851: attempting to get main_ref_store outside of repository
Let's work around this, simply by ignoring the `includeif.onbranch:`
setting when parsing the config when the ref store has not been
initialized (yet).
Technically, there is a way to solve this properly: teach the refs
machinery to initialize the ref_store from a given gitdir/commondir pair
(which we _do_ have in the early config code path), and then use that in
`include_by_branch()`. This, however, is a pretty involved project, and
we're already in the feature freeze for Git v2.23.0.
Note: when calling above-mentioned two commands _outside_ of any Git
worktree (passing the `--global` flag to `git config`, as there is
obviously no repository config available), at the point when
`include_by_branch()` is called, `the_repository` is `NULL`, therefore
we have to be extra careful not to dereference it in that case.

repack: simplify handling of auto-bitmaps and .keep files
Commit 7328482253 (repack: disable bitmaps-by-default if .keep files
exist, 2019-06-29) taught repack to prefer disabling bitmaps to
duplicating objects (unless bitmaps were asked for explicitly).
But there's an easier way to do this: if we keep passing the
--honor-pack-keep flag to pack-objects when auto-enabling bitmaps, then
pack-objects already makes the same decision (it will disable bitmaps
rather than duplicate). Better still, pack-objects can actually decide
to do so based not just on the presence of a .keep file, but on whether
that .keep file actually impacts the new pack we're making (so if we're
racing with a push or fetch, for example, their temporary .keep file
will not block us from generating bitmaps if they haven't yet updated
their refs).
And because repack uses the --write-bitmap-index-quiet flag, we don't
have to worry about pack-objects generating confusing warnings when it
does see a .keep file. We can confirm this by tweaking the .keep test to
check repack's stderr.

repack: silence warnings when auto-enabled bitmaps cannot be built
Depending on various config options, a full repack may not be able to
build a reachability bitmap index (e.g., if pack.packSizeLimit forces us
to write multiple packs). In these cases pack-objects may write a
warning to stderr.
Since 36eba0323d (repack: enable bitmaps by default on bare repos,
2019-03-14), we may generate these warnings even when the user did not
explicitly ask for bitmaps. This has two downsides:
- it can be confusing, if they don't know what bitmaps are
- a daemonized auto-gc will write this to its log file, and the
presence of the warning may suppress further auto-gc (until
gc.logExpiry has elapsed)
Let's have repack communicate to pack-objects that the choice to turn on
bitmaps was not made explicitly by the user, which in turn allows
pack-objects to suppress these warnings.

After our test snippet finishes, the .keep file is left in place, making

The iteration order of a hashmap is undefined, and may depend on things
like the exact set of items added, or the table has been grown or
shrunk. In the case of an oidmap, it even depends on endianness, because
we take the oid hash by casting sha1 bytes directly into an unsigned
int.
Let's sort the test-tool output from any hash iterators. In the case of
t0011, this is just future-proofing. But for t0016, it actually fixes a
reported failure on the big-endian s390 and nonstop ports.
I didn't bother to teach the helper functions to optionally sort output.
They are short enough that it's simpler to just repeat them inline for
the iteration tests than it is to add a --sort option.

git: avoid calling aliased builtins via their dashed form

As of 595d59e2b53 (git.c: ignore pager.* when launching builtin as
dashed external, 2017-08-02), Git wants to ignore the pager.* config
setting when expanding aliases. So let's strip out the

The default location for `.exe` files linked by Visual Studio depends on
the mode (debug vs release) and the architecture. Meaning: after a full
build, there is a `git.exe` in the top-level directory, but none of the
built-ins are linked..
When running a test script in Git Bash, it therefore would pick up the
wrong, say, `git-receive-pack.exe`: the one installed at the same time
as the Git Bash.

msvc: add a Makefile target to pre-generate the Visual Studio solution
The entire idea of generating the VS solution makes only sense if we
generate it via Continuous Integration; otherwise potential users would
still have to download the entire Git for Windows SDK.
If we pre-generate the Visual Studio solution, Git can be built entirely
within Visual Studio, and the test scripts can be run in a regular Git
for Windows (e.g. the Portable Git flavor, which does not include a full
GCC toolchain and therefore weighs only about a tenth of Git for
Windows' SDK).
So let's just add a target in the Makefile that can be used to generate
said solution; The generated files will then be committed so that they
can be pushed to a branch ready to check out by Visual Studio users.
To make things even more useful, we also generate and commit other files
that are required to run the test suite, such as templates and
bin-wrappers: with this, developers can run the test suite in a regular
Git Bash after building the solution in Visual Studio.
Note: for this build target, we do not actually need to initialize the
`vcpkg` system, so we don't.

contrib/buildsystems: add a backend for modern Visual Studio versions
Based on the previous patches in this patch series that fixed the
generator for `.vcproj` files (which were used by Visual Studio prior to
2015 to define projects), this patch offers to generate project
definitions for neweer versions of Visual Studio (which use `.vcxproj`
files).
To that end, this patch copy-edits the generator of the `.vcproj`.
In addition, we now use the `vcpkg` system which allows us to build
Git's dependencies (e.g. curl, libexpat) conveniently. The support
scripts were introduced in the `jh/msvc` patch series, and with this
patch we initialize the `vcpkg` conditionally, in the `libgit` project's
`PreBuildEvent`. To allow for parallel building of the projects, we
therefore put `libgit` at the bottom of the project hierarchy.
