[RFC PATCH v3 03/11] cli: add --thread= option to notmuch-show

The possible values are --thread=none|entire|match.

`entire' is exactly the existing option --entire-thread.

`match' is exactly the existing case when --entire-thread is not specified.

`none' is a new option to return just the matching messages with no
threading information at all.

The `none' option is used by notmuch-pick.el to display an unthreaded
message view (e.g., for an inbox). It is also useful for displaying a
single message in the notmuch-pick view as show/emacs is much faster at
showing a single message than the whole thread.

The default remains as before: `match' in all cases except when
--format=json is specified when `entire' is used.
