This commit enables cpu, mem, block, and mutex profling of the FZF
executable. To support flushing the profiles at program exit it adds
util.AtExit to register "at exit" functions and mandates that util.Exit
is used instead of os.Exit to stop the program.

So that it can determine if it should subtract 1 from $FZF_PREVIEW_LINES
to avoid scrolling issue of Sixel image that touches the bottom of the
screen.
Progress:
* Sixel image can now be displayed with other text, and is scrollable
* If an image can't be displayed entirely due to the scroll offset, fzf
will render a wireframe to indicate that an image should be displayed
* Renamed $FZF_PREVIEW_{WIDTH,HEIGHT} to $FZF_PREVIEW_PIXEL_{WIDTH,HEIGHT}
for clarity
* Added bin/fzf-preview.sh script to demonstrate how to display an image
using Kitty or Sixel protocol
An example:
ls *.jpg | fzf --preview='seq $((FZF_PREVIEW_LINES*9/10)); fzf-preview.sh {}; seq 100'
A known issue:
* If you reduce the size of the preview window, the image may extend
beyond the preview window
Close#3228
* Works inside and outside of tmux
* There is a problem where fzf unnecessarily displays the scroll offset
indicator at the topbright of the screen when the image just fits the
preview window. This is because `kitty icat` generates an extra line
after the image area.
# A 5-row images; an extra row at the end confuses fzf

# to redraw the image on terminal resize or on 'change-preview-window',
# you need to use --transfer-mode=stream.

Currently there is not option to bind ctrl-delete and shift-delete. As
suggested by issue #3240, shift-delete could be used to bind "delete
entry from history" as it is a common way to do so in other
applications, e.g. browsers.
This, however, does only implement to use the key combination itself and
does not assign a default action to any of them. This does enable to
call one's all predefined actions. With the exec action this can
expanded like the issue #3240 suggested.
If desirable, the key combinations could later get a default behavior.

Can we find a better name? I have considered the followings.
* 'point', because "the pointer" points to the current item.
* 'shift', 'switch', 'move', etc. These are not technically correct
because the current item can change without cursor movement (--tac,
reload, search update)
* 'change' is already taken. 'change-current' feels a bit wordy and
sounds wrong, 'current-changed' is wordy and doesn't go well with the
other event names
* 'target', not straightforward
Close#3053
* Default border style on Windows is changed to `sharp` because some
Windows terminals are not capable of displaying `rounded` border
characters correctly.
* If your terminal emulator renders each box-drawing character with
2 columns, set `RUNEWIDTH_EASTASIAN` environment variable to `1`.
- `--phony` renamed to `--disabled` for consistency
- `--no-phony` is now `--enabled`
- Added `enable-search`, `disable-search`, and `toggle-search` actions
for `--bind`
- Added `--color` options: `query` and `disabled`
Close#2303
Fix#2254
- Properly handle extra chars in the buffer. Patch suggested by @mckelly2833.
- Support alt-arrow sequences in \e[1;3A format
- Support shift-alt-arrow sequences in \e[1;10A format
Fix#2212
