[PATCH v8 0/4] worktree: list functions and command

Changes from v7[1]:

	- Reworked history to try to maintain blame from moving functions 
	  from branch.c

	- Removed the worktree_list struct (linked list) and instead return
	  return an array of worktrees.  An alternative was also proposed to
	  include a `next` pointer in the worktree struct.  I coded this 
	  option separately (found in my github fork[2]), but ultimately felt
	  that the array was more managable from a client perspective.

	- Removed the `--skip-bare` and `--verbose` command line options for 
	  `worktree list`.

	- The default output of the includes all of the details which were
	  previously only included in verbose output.  Sample output:

		$git worktree list
		/Users/me/code/bare-git-source         (bare)
		/Users/me/code/worktree-git-from-bare  7ecec52 [master]
		/Users/me/code/wt2                     8681989 (detached HEAD)

	- Added `--porcelain` option to the worktree list command.  

		$git worktree list --porcelain
		worktree /Users/mike/code/bare-git-source
		bare
		
		worktree /Users/mike/code/worktree-git-from-bare
		branch master
		
		worktree /Users/mike/code/wt2
		detached at 8681989
