Remove search context from browser window, simplify search interface for front ends.

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.
