Added content interface for search.
Removed bw->cur_search search context. Desktop layer now does nothing
except pass search requests from front end onto the bw's current_content
via the content interface.
Search API reduced to a pair of functions at each level:
{desktop|content|html|textplain}_search
and
{desktop|content|html|textplain}_search_clear
Updated front ends to use simplified search API. Only tested GTK and RO builds.
These confine the search stuff to render/. However search still uses struct
selection. The handling for which is still spread over desktop/ and render/.
Also the render/search code itself still fiddles inside html and textplain
privates.
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.
+ Split up browser window and content related elements of html & text search.
+ Associate search contexts with contents, rather than browser windows.
+ Remove highlighting of search terms dependency on current_redraw_browser.
+ Fixes issues with search contexts being applied to the wrong content.

* Make content handlers responsible for setting READY/DONE state & emitting events.
* Stop content_convert doing this when there is a registered convert function for the content type.

handlers.
+ Disentangle all box tree manipulation from browser window
code and put it where it belongs.
+ Move other content specific and other irrelevant code from
browser window handling to appropriate places.
+ Put mouse state enum in new mouse header, since it's not just
used by browser window code, and it is used by treeview
windows on the treeview branch.

Remaining work:
1) Clone content_html_data
2) Cloning content_css_data requires the charset of the old content
3) Calling hlcache_handle_abort() before a content has been created must clean up the retrieval context.
