b96c5e3687 With incremental search, start empty and only repeat the previous search 
if the user tries to search again with an empty prompt. This matches
emacs behaviour more closely.

2154e1f4fb Search marks outside the visible text are not useful, so there is no 
point in allocating a big buffer to store them - just allocate the
visible text size, and ignore any outside.

c4732af006 Some improvements to performance of searching: 
- Do not allow searches to be repeated at intervals of less than 50
  milliseconds, to prevent a huge queue of repeat key presses blocking
  up everything for ages.

- If the search text hasn't changed, the match count can't have changed
  and there is no need to do a full search, so only search the visible
  text. This includes both scrolling and repeating the search.

- Do not redraw twice when jumping to the search location.

3a5219c6d0 Instead of storing all UTF-8 characters in the extended cell which means 
that 14 bytes are wasted for each character in the BMP, only store
characters of three bytes or less in the cell itself and store others
(outside the BMP or with combining characters) in a separate global
tree. Can reduce grid memory use for heavy Unicode users by around 30%.

ff8dd150e0 Add a mark in copy mode. Set with set-mark command (bound to 'X') by 
default and the mark and cursor position are swapped with 'jump-to-mark'
(bound to M-x). The line containing the mark is shown in
copy-mode-mark-style with the horizontal position in reverse.

9605b080f6 Do not hoke into struct window_pane from the tty code and instead set 
everything up in tty_ctx. Provide a way to initialize the tty_ctx from a
callback and use it to let popups draw directly through input_parse in
the same way as panes do, rather than forcing a full redraw on every
change.

2391fe23ab Copy mode search improvements: 
- Add styles for the search marking styles (copy-mode-match-style and
  copy-mode-current-match-style).

- Show the current match (the one with the cursor on it) in a different style.

- Copying without a selection will copy the current match if there is one.

f03b61131b Drop having a separate type for style options and make them all strings, 
which allows formats to be expanded. Any styles without a '#{' are still
validated when they are set but any with a '#{' are not. Formats are not
expanded usefully in many cases yet, that will be changed later.

To make this work, a few other changes:

- set-option -a with a style option automatically appends a ",".

- OSC 10 and 11 don't set the window-style option anymore, instead the
  fg and bg are stored in the pane struct and act as the defaults that
  can be overridden by window-style.

- status-fg and -bg now override status-style instead of trying to keep
  them in sync.

c0602f357d Now that copy mode copies the pane content rather than keeping a 
reference to it, it isn't necessary that the pane in copy mode is the
same as the one copying from. Add a -s flag to copy-mode to specify a
different pane for the source content. This means it is possible to view
two places in a pane's history at the same time in different panes, or
copy from a pane's history into an editor or shell in the same pane.
