patch: implement worktree support

Implement worktree support for the patch management.

Use ":patch apply -w <commit-ish> <tag>" to create a new worktree and
apply the selected messages to it. The worktree is linked to repo in the
current project.

Internally, the worktree is stored as a new project. When this project
is deleted with ":patch delete", the underlying linked worktree is
removed as well.

":patch list" shows when a project is a worktree and to what project it
is linked to.

Worktrees enable the users to create a new copy of the repo at a given
commit and apply patches without interrupting the current work in the
base repo.
