or the current window's buffer

and the following new commands:

`do-compile`, and switch interactive shell buffers to
`compilation` mode when the shell exits (if `shell_buffer_read_only` is set)
* refine popup/sidepane closing in `next-error`:
* remove unnecessary popup check, as the command cannot
be invoked if a popup window is present.
* use `do_delete_window` to close side pane to avoid
screen gap bug with `edit_close`.
* add `split-window-left`, `split-window-right`, `split-window-above`
and `split-window-below` to specify how to split window portably.

charcaters in buffer or file names:
- U toggles unicode display
- \ cycles through 4 possible encodings: ? ^J \x10 \010
* use `(*fp)()` syntax for indirect function calls
The behavior follows this priority order:
1. reuse an existing window already displaying the buffer,
2. if shell-command-other-window is not set, use the current
window, otherwise
3. select the largest available non-active window.
4. split a new window if no sutiable window is found.
5. fall back to the current window if splitting fails.
* improve block skipping:
- if starting inside a string or a comment, skip to the end of the
string or comment while balancing blocks
- otherwise skip string and comments when balancing blocks
- fix behavior on very long lines, eg: **highlight.pack.js**

delimiters. use C-x C-x to skip between them

* add `eb_peek_prevc()` to get previous codepoint without end offset
* improve documentation conciseness

* this ensures the `*occur*` buffer stays current in windows that show it
* modify the `BC_CLEAR` semantics to imply `BC_REUSE`
* simplify calls: remove redundant `BC_REUSE` flag
- `shell_buffer_read_only` controls if the shell buffer should become
read-only and use pager-mode when not interactive

switched to and from automatically based on cursor movement commands

* rename `update_split_ratio` as `compute_virtual_window_size`
* remove `update_all_split_ratios` and `restore_coordinate_from_ratio`
* recompute window size in more necessary places
* use character sizes for minimum window width/height
* show virtual window size in `describe-window`
* add `C-x V` binding for `shrink-window`
In the signal handler for the signal SIGWINCH tty_term_resize, we call
tty_dpy_invalidate function. In this function, we change the screen_size
and other critical fields.
While the process is executing the function tty_dpy_flush, and another
SIGWINCH occurs, then the screen_size is changed. And tty_dpy_flush will
access invalid memory which leads to coredump.
In the signal hander of SIGWINCH, we only need to set the flag
complete_refresh.
