search: add more key bindings to extend the current match

This patch adds the following new search key bindings:

* extend-char (shift+right)
* extend-line-down (shift+down)
* extend-backward-char (shift+left)
* extend-backward-to-word-boundary (ctrl+shift+left)
* extend-backward-to-next-whitespace (ctrl+shift+alt+left)
* extend-line-up (shift+up)

They can be used to extend the search match (i.e. the selection).

This patch also adds an initial set of key bindings to scroll in the
scrollback history:

* scrollback-up-page
* scrollback-down-page

These work just like the key bindings for the normal mode. Also note
that it was already possible to scroll using the mouse.

This patch also fixes a couple of search mode bugs:

* crashing when a search match ends in the last column
* grapheme clusters not being matched correctly
* Search match not being "extendable" after a pointer leave event
* A few others, related to either large matches, or extending matches
  after moving the viewport.

There are still a couple of (known) issues:

* A search match isn't correctly highlighted if its *starting* point
  is outside the viewport.
* Extending the match to end of the scrollback (i.e. the most recent
  output) is simply buggy.
