Loads of changes including fixes, new functionality, and optimisation.
...
+ Refactor internals to be byte, rather than character based.
+ Don't need to hammer utf8_* functions everywhere
+ Optimises:
+ Redraw (lots)
+ Editing (insertion, replacement, removal)
+ Caret placement
+ Selection
+ Early avoid of zero length autoscroll during selection drag.
+ Optimised redraw to avoid nsfont_width when:
+ There's no selection at all.
+ We're on last part of line, and it's unselected.
+ Implemented WORD_LEFT and WORD_RIGHT keys (shift + cursor left/right)
+ Fixed UP and DOWN (cursor up/down) keys to handle non-monospace fonts.
(Now based on 'x' offset on line, rather than character offset on line.)
+ Fixed PAGE_UP and PAGE_DOWN to scroll without moving the caret.
+ Fixed redraw bug in text selection edge case.
+ Changed textarea_replace_text and textarea_insert_text to return
a byte delta for caret position changes.
+ Coordinate to text offset function handles global and viewport coords.
+ Many small improvements and tidying.

A load of refactoring of how content selection and input work.
...
Keypresses now go via content interface.
Contents don't shove the selection object into browser windows any more.
Contents report selection existence by sending message.
HTML content keeps track of where selections in it exist.
Contents report whether they have input focus via caret setting msg.
Caret can be hidden (can still input/paste) or removed.
Consolidate textarea selection handling.
Make textarea report its selection status changes to client.
Various textarea fixes.
Changed how we decide when to clear selections, and give focus.

Calculate and store text offsets only when they change, rather than recalculating on every redraw and caret placement. Also ensures that caret placement and redraw get the same text offset values.

Implement selection modification. Clicks and drags with button 2 alter the nearest end of the selection. Button 2 when there is no selection selects from caret pos to click pos.

Single line textareas don't have scrollbars, so they don't get the scroll redraw request from the scrollbar callback.

If a character is replaced by a character of different width, the caret needs to move. Checking change in character index isn't enough, so move caret if redraw was required too.
