We need this later to avoid double locking a worktree, or unlocking one
when it's not even locked.

Main worktree _is_ different. You can lock (*) a linked worktree but not
the main one, for example. Provide an API for checking that.
(*) Add the file $GIT_DIR/worktrees/xxx/locked to avoid worktree xxx
from being removed or moved.

So far we haven't needed to identify an existing worktree from command
line. Future commands such as lock or move will need it. The current
implementation identifies worktrees by path (*). In future, the function
could learn to identify by $(basename $path) or tags...
(*) We could probably go cheaper with comparing inode number (and
probably more reliable than paths when unicode enters the game). But not
all systems have good inode that so let's stick to something simple for
now.

The branch name in that case could be saved in rebase's head_name or
bisect's BISECT_START files. Ideally we should try to update them as
well. But it's trickier (*). Let's play safe and see if the user
complains about inconveniences before doing that.
(*) If we do it, bisect and rebase need to provide an API to rename
branches. We can't do it in worktree.c or builtin/branch.c because
when other people change rebase/bisect code, they may not be aware of
this code and accidentally break it (e.g. rename the branch file, or
refer to the branch in new files). It's a lot more work.

do_git_path(), which is the common code for all git_path* functions, is
modified to take a worktree struct and can produce paths for any
worktree.
worktree_git_path() is the first function that makes use of this. It can
be used to write code that can examine any worktree. For example,
wt_status_get_state() will be converted using this to take
am/rebase/... state of any worktree.

This gives the caller more information and they can answer things like,
"is it the main worktree" or "is it the current worktree". The latter
question is needed for the "checkout a rebase branch" case later.

We can reconstruct git_dir from id quite easily. It's a bit hackier to
do the reverse.

In addition to the absolute path in the worktree struct, add the location
of the git dir, the head ref (if not detached), the head revision sha1,
whether or not head is detached, and whether or not the worktree is a
bare repo.

The worktree structure provided for an individual worktree includes the
absolute path of the worktree. The fuction to get the worktree details
is a refactor of the find main/linked symref functions.

worktree.c contains functions to work with and get information from
worktrees. This introduction moves functions related to worktrees
from branch.c into worktree.c
