f276e2a469 config: improve error message for boolean config
Currently invalid boolean config values return messages about 'bad
numeric', which is slightly misleading when the error was due to a
boolean value. We can improve the developer experience by returning a
boolean error message when we know the value is neither a bool text or
int.

before with an invalid boolean value of `non-boolean`, its unclear what
numeric is referring to:
  fatal: bad numeric config value 'non-boolean' for 'commit.gpgsign': invalid unit

now the error message mentions `non-boolean` is a bad boolean value:
  fatal: bad boolean config value 'non-boolean' for 'commit.gpgsign'

c809798b2a reflog expire --stale-fix: be generous about missing objects
Whenever a user runs `git reflog expire --stale-fix`, the most likely
reason is that their repository is at least _somewhat_ corrupt. Which
means that it is more than just possible that some objects are missing.

If that is the case, that can currently let the command abort through
the phase where it tries to mark all reachable objects.

Instead of adding insult to injury, let's be gentle and continue as best
as we can in such a scenario, simply by ignoring the missing objects and
moving on.

a38cb9878a mailmap: only look for .mailmap in work tree
When trying to find a .mailmap file, we will always look for it in the
current directory. This makes sense in a repository with a working tree,
since we'd always go to the toplevel directory at startup. But for a
bare repository, it can be confusing. With an option like --git-dir (or
$GIT_DIR in the environment), we don't chdir at all, and we'd read
.mailmap from whatever directory you happened to be in before starting
Git.

(Note that --git-dir without specifying a working tree historically
means "the current directory is the root of the working tree", but most
bare repositories will have core.bare set these days, meaning they will
realize there is no working tree at all).

The documentation for gitmailmap(5) says:

  If the file `.mailmap` exists at the toplevel of the repository[...]

which likewise reinforces the notion that we are looking in the working
tree.

This patch prevents us from looking for such a file when we're in a bare
repository. This does break something that used to work:

  cd bare.git
  git cat-file blob HEAD:.mailmap >.mailmap
  git shortlog

But that was never advertised in the documentation. And these days we
have mailmap.blob (which defaults to HEAD:.mailmap) to do the same thing
in a much cleaner way.

However, there's one more interesting case: we might not have a
repository at all! The git-shortlog command can be run with git-log
output fed on its stdin, and it will apply the mailmap. In that case, it
probably does make sense to read .mailmap from the current directory.
This patch will continue to do so.

That leads to one even weirder case: if you run git-shortlog to process
stdin, the input _could_ be from a different repository entirely. Should
we respect the in-tree .mailmap then? Probably yes. Whatever the source
of the input, if shortlog is running in a repository, the documentation
claims that we'd read the .mailmap from its top-level (and of course
it's reasonably likely that it _is_ from the same repo, and the user
just preferred to run git-log and git-shortlog separately for whatever
reason).

The included test covers these cases, and we now document the "no repo"
case explicitly.

We also add a test that confirms we find a top-level ".mailmap" even
when we start in a subdirectory of the working tree. This worked both
before and after this commit, but we never tested it explicitly (it
works because we always chdir to the top-level of the working tree if
there is one).

e89f89361c fsck --name-objects: be more careful parsing generation numbers
In 7b35efd734 (fsck_walk(): optionally name objects on the go,
2016-07-17), the `fsck` machinery learned to optionally name the
objects, so that it is easier to see what part of the repository is in a
bad shape, say, when objects are missing.

To save on complexity, this machinery uses a parser to determine the
name of a parent given a commit's name: any `~<n>` suffix is parsed and
the parent's name is formed from the prefix together with `~<n+1>`.

However, this parser has a bug: if it finds a suffix `<n>` that is _not_
`~<n>`, it will mistake the empty string for the prefix and `<n>` for
the generation number. In other words, it will generate a name of the
form `~<bogus-number>`.

Let's fix this.

41abfe15d9 maintenance: add pack-refs task
It is valuable to collect loose refs into a more compressed form. This
is typically the packed-refs file, although this could be the reftable
in the future. Having packed refs can be extremely valuable in repos
with many tags or remote branches that are not modified by the local
user, but still are necessary for other queries.

For instance, with many exploded refs, commands such as

	git describe --tags --exact-match HEAD

can be very slow (multiple seconds). This command in particular is used
by terminal prompts to show when a detatched HEAD is pointing to an
existing tag, so having it be slow causes significant delays for users.

Add a new 'pack-refs' maintenance task. It runs 'git pack-refs --all
--prune' to move loose refs into a packed form. For now, that is the
packed-refs file, but could adjust to other file formats in the future.

This is the first of several sub-tasks of the 'gc' task that could be
extracted to their own tasks. In this process, we should not change the
behavior of the 'gc' task since that remains the default way to keep
repositories maintained. Creating a new task for one of these sub-tasks
only provides more customization options for those choosing to not use
the 'gc' task. It is certainly possible to have both the 'gc' and
'pack-refs' tasks enabled and run regularly. While they may repeat
effort, they do not conflict in a destructive way.

The 'auto_condition' function pointer is left NULL for now. We could
extend this in the future to have a condition check if pack-refs should
be run during 'git maintenance run --auto'.

0a9dde4a04 usage: trace2 BUG() invocations
die() messages are traced in trace2, but BUG() messages are not. Anyone
tracking die() messages would have even more reason to track BUG().
Therefore, write to trace2 when BUG() is invoked.

98ea309b3f mergetool: add hideResolved configuration
The purpose of a mergetool is to help the user resolve any conflicts
that Git cannot automatically resolve. If there is a conflict that must
be resolved manually Git will write a file named MERGED which contains
everything Git was able to resolve by itself and also everything that it
was not able to resolve wrapped in conflict markers.

One way to think of MERGED is as a two- or three-way diff. If each
"side" of the conflict markers is separately extracted an external tool
can represent those conflicts as a side-by-side diff.

However many mergetools instead diff LOCAL and REMOTE both of which
contain versions of the file from before the merge. Since the conflicts
Git resolved automatically are not present it forces the user to
manually re-resolve those conflicts. Some mergetools also show MERGED
but often only for reference and not as the focal point to resolve the
conflicts.

This adds a `mergetool.hideResolved` flag that will overwrite LOCAL and
REMOTE with each corresponding "side" of a conflicted file and thus hide
all conflicts that Git was able to resolve itself. Overwriting these
files will immediately benefit any mergetool that uses them without
requiring any changes to the tool.

No adverse effects were noted in a small survey of popular mergetools[1]
so this behavior defaults to `true`. However it can be globally disabled
by setting `mergetool.hideResolved` to `false`.
