[PATCH 2/7] emacs/tree: add notmuch-tree-goto-matching-message

[William Casarin]

This function captures some common logic when jumping to matching
messages in notmuch-tree mode.

We also add a new return value (t or nil), that indicates if there was
a next matching message in the thread to show.

[PATCH 3/7] emacs/tree: add notmuch-tree-matching-message

[William Casarin]

This functions removes some duplicate logic between
notmuch-tree-{next,prev}-matching-message

We do this because we will be adding some additional logic similar to
the notmuch-show-next-open-message function, and it will help if this
logic is all in one place.
