The screen resize logic needs to be refactored to be simpler and more
deterministic. Until then, we need to handle attempts to draw outside of the
screen size gracefully, just like the old vim code did.
fixes#9989
Problem: In screen.c grid_char_needs_redraw clang warns
that grid->chars could be NULL
Solution: Suggested by bfredl. Add explicit check
grid->chars != NULL in grid_put_linebuf
similar to grid_puts_len
Suppress the warning.
mb_c and mb_l describe a char together, they are not independent variables. The
coupled assignments are good practice to avoid future confusion, even if the
current code doesn't use an assigned value.
Problem: Tabline is not always redrawn when something that is used in
'tabline' changes.
Solution: Add ":redrawtabline" so that a plugin can at least cause the
redraw when needed.

Note: test doesn't fail on master. I cannot reproduce the glitches with
-u NONE, probably it requires interfering events. But add some coverage
for these checks at least.
Problem: Stuck in redraw loop when 'lazyredraw' is set.
Solution: Don't loop on update_screen() when not redrawing. (Yasuhiro
Matsumoto, closesvim/vim#2082)

Problem: Some macros are used without a semicolon, causing auto-indent to be
wrong.
Solution: Use the do-while(0) trick. (Ozaki Kiichi, closesvim/vim#2729)

* screen: Fix to draw signs with combining characters.
The buffer size for signs can be too small, because the upper length
limit of a sign can be 56 bytes. If combining characters are only two
bytes in size, this reduces to 32 bytes.
* screen: Adjust buffer size to maximal sign column count
Problem: Cannot tell whether a register is being used for executing or
recording.
Solution: Add reg_executing() and reg_recording(). (Hirohito Higashi,
closesvim/vim#2745) Rename the global variables for consistency. Store
the register name in reg_executing.

Problem: Windows are updated for every added/deleted sign.
Solution: Do not call update_debug_sign(). Only redraw when the line with
the sign is visible. (idea from neovim vim/vim#9479)

Problem: Functionality for signs is spread out over several files.
Solution: Move most of the sign functionality into sign.c. (Yegappan
Lakshmanan, closesvim/vim#3751)

Problem: Hang when concealing the '>' shown for a wide char that doesn't
fit in the last cell.
Solution: Put back the pointer when the '>' is not going to be displayed.

Problem: "extends" from 'listchars' is used when 'list' is off. (Hiroyuki
Yoshinaga)
Solution: Only use the "extends" character when 'list' is on. (Hirohito
Higashi, closesvim/vim#4360)

Problem: When 'listchars' only contains "nbsp:X" it does not work.
Solution: Set extra_check when lcs_nbsp is set. (Ralf Schandl, closesvim/vim#3889)

Problem: Finished job in terminal window is not handled.
Solution: Add the scrollback buffer. Use it to fill the buffer when the job
has ended.

Problem: Syntax timeout not used correctly.
Solution: Do not pass the timeout to syntax_start() but set it explicitly.

- Allow floating windows of width 1. #9846
- For a new floating window the size must be specified. Later on we
might try to calculate a reasonable size by buffer contents
- Remember the configured size of a window, just like its position.
- Make get_config and set_config more consistent. Handle relative='' properly in set_config.
get_config doesn't return keys that don't make sense for a non-floating window.
- Don't use width=0 for non-changed width, just omit the key.
Problem: Extending sign and foldcolumn below the text is confusing.
Solution: Let the sign and foldcolumn stop at the last text line, just like
the line number column. Also stop the command line window leader.

Problem: "Conceal" match is mixed up with 'hlsearch' match.
Solution: Check that a match is found, not a 'hlsearch' item. (Andy
Massimino, closesvim/vim#4073)
