Summary:
a [git worktree](https://git-scm.com/docs/git-worktree) allows for a single repository to have multiple local checkouts in different directories (allowing parallel work on multiple branches of the same repo).
in such a worktree, `.git` is a file and not a directory:
```
$ cat .git
gitdir: /path/to/actual/repo/.git/worktrees/name
```
the `_git_prompt` helper in `scm-prompt.sh` expects only directories:
```
$ echo "$(_git_prompt /path/to/worktree/.git)"
# (output is empty)
```
this amends the helper to support them:
```
$ echo "$(_git_prompt /path/to/worktree/.git)"
f140443f|REBASE-i|T123456
$ echo "$(_git_prompt /path/to/parent/.git)"
T54321
```

Summary:
Copied from D17312417 (e1f4dbeb3d), because that did what I needed done, but incremented by 1.
I would like to change the length of the displayed hash in scm-prompt
to 9. Why such an impactful diff? Because hg sl shows 9 characters, and I
always get confused when the hash in my prompt doesn't match hg sl

Summary:
Added an optional feature to scm-prompt.sh to show the dirty state of the working directory.
Users need to opt in by set the environmental variable `SHOW_DIRTY_STATE` to yes (or whatever nonempty string) in their shell rc file. The idea is that users who do not need/want this feature should see minimal performance hit of their prompt.
Unfortunately, in some (large) repos, calling `hg status` or `git diff` to figure out the dirty state can slow down showing the prompt quite a bit. So, in this case, user can opt out individual repo by setting `shell.showDirtyState` in .hg/hgrc or .git/config.

Summary:
Similar to D17199834, by moving 'bookmarks' from localvfs and sharedvfs to
storevfs, we can make it part of metalog and get better transaction support.

Summary:
In preparation for merging fb-mercurial sources to the Eden repository,
move everything from the top-level directory into an `eden/scm`
subdirectory.
