Problem:
During a refactor long ago, we changed the `getdigits_*` familiy of
functions to abort on overflow. But this is often wrong, because many
of these codepaths are handling user input.
Solution:
Decide at each call-site whether to use "strict" mode.
fix#5555
Problem: Existing color schemes don't work well with StatusLineTerm.
Solution: Don't use "reverse", use fg and bg colors. Also add
StatusLineTermNC.

(We don't implement StatusLineTerm{NC}, but this patch seems generally relevant.)
Problem: if there is no StatusLine highlighting and there is StatusLineNC
or StatusLineTermNC highlighting then an invalid highlight id is
passed to combine_stl_hlt(). (Coverity)
Solution: Check id_S to be -1 instead of zero.

Problem: Highlighting in quickfix window could be better. (Axel Bender)
Solution: Use the qfSeparator highlight item. (Yegappan Lakshmanan)

This adds `syn_name2attr` already (from previous patch 8.0.1123,
vim/vim@1b9645de3).
Problem: Cannot get the script line number when executing a function.
Solution: Store the line number besides the script ID. (Ozaki Kiichi,
closesvim/vim#3362) Also display the line number with ":verbose set".

add proper msg_set_pos event, delet win_scroll_over_*
make compositor click through unfocusable grids
add MsgArea attribute for the message/cmdline area, and add docs and tests
Problem: Changing StatusLine highlight while evaluating 'statusline' may
not change the status line color.
Solution: When changing highlighting while redrawing don't cause another
redraw. (suggested by Ozaki Kiichi, closesvim/vim#2171, closesvim/vim#2120)

Problem: Redraw when highlight is set with same names. (Ozaki Kiichi)
Solution: Only free and save a name when it changed. (closesvim/vim#2120)

ext_message doesn't set msg_col. Add a space and let client deal with
wrapping. When using silent redirect show the unwrapped message form.
Removed check is already part of msg_advance()
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: Syntax timeout not used correctly.
Solution: Do not pass the timeout to syntax_start() but set it explicitly.
(Yasuhiro Matsumoto, closesvim/vim#2139)

Problem: When 'hlsearch' is set and matching with the last search pattern
is very slow, Vim becomes unusable. Cannot quit search by
pressing CTRL-C.
Solution: When the search times out set a flag and don't try again. Check
for timeout and CTRL-C in NFA loop that adds states.

Note about shada.c:
- shada_read_next_item_start was intentionally shadowing `unpacked` and
`i` because many of the macros (e.g. ADDITIONAL_KEY) implicitly
depended on those variable names.
- Macros were changed to parameterize `unpacked` (but not `i`). Macros
like CLEAR_GA_AND_ERROR_OUT do control-flow (goto), so any other
approach is messy.
Problem: Segfault when pattern with \z() is very slow.
Solution: Check for NULL regprog. Add "nfa_fail" to test_override() to be
able to test this. Fix that 'searchhl' resets called_emsg.

Avoid clearing the screen in most situations. NOT_VALID should be
equivalent to CLEAR unless some external force messed up the terminal,
for these situations <c-l> and :mode will still clear the screen.
Also eliminate some obsolete code in screen.c, that dealt with that in
vim drawing window 1 can mess up window 2, but this never happens in
nvim.
But what about slow terminals? There is two common meanings in which
a terminal is said to be "slow":
Most commonly (and in the sense of vim:s nottyfast) it means low
bandwidth for sending bytes from nvim to the terminal. If the screen is
very similar before and after the update_screen(CLEAR) this change
should reduce bandwidth. If the screen is quite different, but there is
no new regions of contiguous whitespace, clearing doesn't reduce
bandwidth significantly. If the new screen contains a lot of whitespace,
it will depend of if vsplits are used or not: as long as there is no
vsplits, ce is used to cheaply clear the rest of the line, so
full-screen clear is not needed to reduce bandwith. However a left
vsplit currently needs to be padded with whitespace all the way to the
separator. It is possible ec (clear N chars) can be used to reduce
bandwidth here if this is a problem. (All of this assumes that one
doesn't set Normal guibg=... on a non-BCE terminal, if you do you are
doomed regardless of this change).
Slow can also mean that drawing pixels on the screen is slow. E-ink
screens is a recent example. Avoiding clearing and redrawing the
unchanged part of the screen will always improve performance in these
cases.
NB: existing `color default` test was actually enough to trigger the bug,
when ext_newgrid=false is used. I created the `:hi Normal` test as
I thought the builtin colors wouldn't set Normal (unless 'bg' is changed)
But as the root cause actually comes from `:hi Normal`, it makes sense
to still add the separate test (if `color default` here gets optimized to
become a no-op, or something).
Give embeders a chance to set up nvim, by processing a request before
startup. This allows an external UI to show messages and prompts from
--cmd and buffer loading (e.g. swap files)
