Merge branch 'vd/scalar-enables-fsmonitor'

"scalar" now enables built-in fsmonitor on enlisted repositories,
when able.

* vd/scalar-enables-fsmonitor:
  scalar: update technical doc roadmap with FSMonitor support
  scalar unregister: stop FSMonitor daemon
  scalar: enable built-in FSMonitor on `register`
  scalar: move config setting logic into its own function
  scalar-delete: do not 'die()' in 'delete_enlistment()'
  scalar-[un]register: clearly indicate source of error
  scalar-unregister: handle error codes greater than 0
  scalar: constrain enlistment search

  Roughly speaking (and subject to change), the following series are needed to
  "finish" this initial version of Scalar:
  
- - Finish Scalar features: Enable the built-in FSMonitor in Scalar enlistments
-   and implement `scalar help`. At the end of this series, Scalar should be
-   feature-complete from the perspective of a user.
 -- Generalize features not specific to Scalar: In the spirit of making Scalar
 -  configure only what is needed for large repo performance, move common
 -  utilities into other parts of Git. Some of this will be internal-only, but one
 -  major change will be generalizing `scalar diagnose` for use with any Git
 -  repository.
--
  - Move Scalar to toplevel: Move Scalar out of `contrib/` and into the root of
-   `git`, including updates to build and install it with the rest of Git. This
-   change will incorporate Scalar into the Git CI and test framework, as well as
-   expand regression and performance testing to ensure the tool is stable.
+   `git`. This includes a variety of related updates, including:
+     - building & installing Scalar in the Git root-level 'make [install]'.
+     - builing & testing Scalar as part of CI.
+     - moving and expanding test coverage of Scalar (including perf tests).
+     - implementing 'scalar help'/'git help scalar' to display scalar
+       documentation.
  
  Finally, there are two additional patch series that exist in Microsoft's fork of
  Git, but there is no current plan to upstream them. There are some interesting
