Stop using `the_repository` in `setup_work_tree()` and instead accept
the repository as a parameter. The injection of `the_repository` is thus
bumped one level higher, where callers now pass it in explicitly.
Note that the function tracks bogus worktree configuration via a global
variable. If we have bogus configuration, and if later on some caller
tries to setup a worktree, then we'll die instead.
Of course, tracking this as a global variable doesn't make sense anymore
now that we can set up worktrees for arbitrary repositories. Move the
variable into `struct repository` instead.

Similar as with the preceding commit, `is_inside_git_dir()` determines
whether the current working directory is located inside the gitdir of
`the_repository`. Perform the same refactoring by dropping the caching
mechanism and injecting the repository that shall be checked.

The function `is_inside_worktree()` verifies whether or not the current
working directory is located inside the worktree of `the_repository`.
This is done by taking the worktree path and verifying that it's a
prefix of the current working directory.
This information is cached so that we don't have to re-do this change
multiple times. Furthermore, we proactively set the value in multiple
locations so that we don't even have to perform the check when we have
discovered the repository.
While we could simply move the caching variable into the repository, the
current layout doesn't really feel sensible in the first place:
- It can easily lead to false positives or negatives if at any point
in time we may switch the current working directory.
- We don't call the function in a hot loop, and neither is it overly
expensive to compute.
Drop the caching infrastructure and instead compute the property ad-hoc
via an injected repository.
Note that there is one small gotcha: we sometimes may end up with
relative directory paths, and if so `is_inside_dir()` might fail. This
wasn't an issue before because of how we proactively set the cached
value during repository discovery. Now that we stop doing that it
becomes a problem though, but it is worked around by resolving the
repository directory via `realpath()`.

Replace the use of `the_repository` in "setup.c" for all static
functions. For now, we simply add `the_repository` to invocations of
these functions. This will be addressed in subsequent commits, where
we'll move up `the_repository` one more layer to callers of "setup.c".

We pair lines for highlighting based on their position in the hunk. So
we should never see two identical lines paired, like:
-one
-two
+one
+something else
which would pair -one/+one, because that implies that the diff could
easily be shrunk by turning line "one" into context.
But there is (at least) one exception: removing a newline at the end of
a file will produce a diff like:
-foo
+foo
\No newline at end of file
And we will pair those two lines. As a result, we end up marking the
whole line, including the newline, as the shared prefix. And there's an
empty suffix.
The most obvious bug here is that when we try to print the highlighted
lines, we remove the trailing newline from the suffix, but do not bother
with the prefix (under the assumption that there had to be a difference
_somewhere_ in the line, and thus the prefix would not eat all the way
up to the newline). And so you get an extra line like:
-foo
+foo
\No newline at end of file
This is obviously ugly, but also causes interactive.diffFilter to
(rightly) complain that the input and output do not match their lines
1-to-1.
This could easily be fixed by chomping the prefix, too, but I think the
problem is deeper. For one, I suspect some of the other logic gets
confused by forming an array with zero-indexed element "3" in a
3-element array. But more importantly, we try not to highlight whole
lines, as there's nothing interesting to show there. So let's catch this
early in is_pair_interesting() and bail to our usual passthrough
strategy.
