'cursorlineopt' (#41785)
Problem: CursorLineFold and CursorLineSign are only applied when
'cursorlineopt' contains "number" or is "both"
(Evgeni Chasnovski).
Solution: Apply those groups whenever 'cursorline' is set, independent
of 'cursorlineopt' (Vrushali Zampalkar).
fixes: vim/vim#20480
closes: vim/vim#21112

context: vim_snprintf provides a "portable" replacement for a system
vsnprintf(). However we rely on system vsnprintf() in places. This
is quite arbitrary. I want to use system vsnprintf() only, and
reduce the machinery in string.c for typval printf only, which will
delet a lot of duplicated code.
The biggest hurdle here is not "portably" (we only support sane c
runtimes) but the following discrepancy: standard libc printf()
considers NULL args to %s to be undefined behavior strictly
while vim_snprintf() _defacto_ allows this by replacement to "[NULL]"
IMO, this should be seen as "graceful" error handling (nicer than crashing
on the user), not a valid means to have the string "[NULL]" intentionally
be shoved in the users face. more robust code should explicitly
check for NULL and replace it with a _appropriate_ fallback for
the situation, depending on what a NULL string actually means in the
context (unnamed buffer? anonymous namespace? global augroup?)
soo, this PR provides the most _gently_ incremental nudge towards
considering this case again as an error one could possible imagine.
If sanitizers are complied in, this minor incursion gets printed
into the sanitizers' log as a "report-and-continue" error with a
traceback. This doesn't annoy the end user or "stop the world"
in the test suite, but the CI will see the reported error and
fail the build, just like other non-fatal CI errors.

Problem:
Undo places the cursor wherever the cursor happened to sit at "save
time" (`uh_cursor` is sampled lazily on the first change).
Examples:
- `i` preserves, but `a` does not
- `diw`, `atest<Esc>`, `d^` abandon the original position
- `D`, `o` restore it (by accident).
Solution:
`composite` tracks the pending atom (and its `origin`) across frames.
A `stuffed` continuation frame inherits the `origin` + prepped redo.
Store `origin` info in the undo header, so undo can restore it.
- Not for a mid-command undo break (i_CTRL-G_u).
- Undoing a mapping restores where the mapping started (which
technically may be different than where the "edit" started).

Problem:
The magic globals `it`, `describe`, etc., are more trouble than they are
worth.
- Hooking into `after_each` requires `getfenv()` hacks.
- They confuse luals/emmylua, because the top-level `.luarc.json` isn't
merged with `test/.luarc.json` (apparently a luals limitation?)
- They totally defeat discoverability because the user just has to
"know" about the various magic symbols.
So they harm DX, which means they serve no purpose at all.
Solution:
- Expose the test API from `testutil`, so tests can call `t.it()`,
`t.describe()`, etc., in the conventional way.
- Drop `getfenv()` hacks.
- Drop the `setfenv()` injection in `load_chunk`.
- Drop `test/_meta.lua`.

Problem: Newlines intended to write messages below the cmdline or to
mark the start of a new message on message grid are emitted
through ext_messages. This results in unnecessary newlines for
a UI that has decoupled its message area from the cmdline.
msg_col is set directly in some places which is not transmitted
to msg_show events.
Various missing message kind for list commands.
Trailing newlines on various list commands.
Solution: Only emit such newlines without ext_messages enabled.
Use msg_advance() instead of setting msg_col directly.
Assign them the "list_cmd" kind.
Ensure no trailing newline is printed.

Problem: When 'signcolumn' is set to `number` but a line has a sign
without text, the line number disappears (finite-state-machine)
Solution: Verify that a sign actually contains text before rendering the
line number (glepnir)

Problem: Computed previous buffer line count may be beyond end of
buffer. This results in signs being removed from `b_signcols`
that were never included in it, tripping an assertion.
Solution: Store the previous line count as it was before appending or
deleting lines. Use it to clamp the edited region when
clearing signs before a splice, after which it is reset.

Problem: Number and statuscolumn highlighting for virtual lines does
not take always take on numhl highlights.
Solution: Apply the appropriate numhl highlight to the number/statuscolumn
of virtual lines, fetching the numhl highlight of the line above
for `virt_line_above == false` lines.

Problem: Combined highlighting was not applied to nvim_eval_statusline(),
and 'statuscolumn' sign segment/numhl highlights.
Solution: Add an additional `groups` element to the return value of
`nvim_eval_statusline()->highlights`. This is an array of stacked
highlight groups (highest priority last). Also resolve combined
highlights for the 'statuscolumn' sign segment/numhl highlights.
Expose/synchronize some drawline.c logic that is now mimicked in
three different places.

Problem:
Since e049c6e4c08a, most statusline-like UI elements can combine
highlight attrs, except for sign/statuscolumn.
Solution:
Implement for sign/statuscolumn.

Before calling "attach" a screen object is just a dummy container for
(row, col) values whose purpose is to be sent as part of the "attach"
function call anyway.
Just create the screen in an attached state directly. Keep the complete
(row, col, options) config together. It is still completely valid to
later detach and re-attach as needed, including to another session.

Problem: Legacy :sign API still allows placing signs beyond the end of
the buffer. This is unaccounted for by the signcolumn tracking
logic and is disallowed in general for the extmark API which
implements it now.
Solution: Clamp legacy sign line number to the length of the buffer.

Problem:
Higher-priority signs may be hidden by lower-priority signs.
Solution:
Place higher-priority signs from the left.
Example:
nvim_buf_set_extmark(0, ns, 0, -1, {sign_text='H', priority=1})
nvim_buf_set_extmark(0, ns, 0, -1, {sign_text='W', priority=2})
nvim_buf_set_extmark(0, ns, 0, -1, {sign_text='E', priority=3})
Before:
| |
H | W E |
^ | |
Not visible
After:
| |
| E W | H
| | ^
Not visible

Specifically, functions that are run in the context of the test runner
are put in module `test/testutil.lua` while the functions that are run
in the context of the test session are put in
`test/functional/testnvim.lua`.

Problem: Wrong "clear" argument passed to buf_signcols_count_range
when initializing "b_signcols.count" for the first time.
Solution: Pass kFalse so that the "nested" counter is not incorrectly
decremented.

refactor(drawline): remove LineDrawState and wlv->saved_n_extra

We do not need an enum to keep track of what place in win_line() we
currently are at. We already have a variable which keeps track where
in the code we currently are (and thus what part of the line we are
currently rendering), it is called the _program counter_. When we need
non-linear or self-referential control-flow anyway for a laugh, we
have a mechanism for that, it is called _function calls_.
Do not "save" and "restore" the wlv->n_extra state every time the
columns are to be drawn. This sort of thing needs to go away. Instead of
setting the n_extra variables and then going to the outer while loop,
the text in the columns can be rendered by just simply putting the text
into the cells of the screen line, right away. Even in nvim this can be
tricky sometimes, luckily we can use function calls to abstract this
logic, which means that this handy data structure called the _call
stack_ is handling saving away state temporarily, and restoring it back
when we need it again.
Lastly, but not least, as we now have direct control how signs
are rendered, these can be stored as schar_T[2] and be directly
put on screen as such.

Problem: Unpaired marks are invalidated if its column is deleted,
which may just be a "placeholder" column, e.g. for signs.
Solution: Only remove unpaired marks if its entire row is deleted.

Problem: The legacy signlist data structures and associated functions are
redundant since the introduction of extmark signs.
Solution: Store signs defined through the legacy commands in a hashmap, placed
signs in the extmark tree. Replace signlist associated functions.
Usage of the legacy sign commands should yield no change in behavior with the
exception of:
- "orphaned signs" are now always removed when the line it is placed on is
deleted. This used to depend on the value of 'signcolumn'.
- It is no longer possible to place multiple signs with the same identifier
in a single group on multiple lines. This will now move the sign instead.
Moreover, both signs placed through the legacy sign commands and through
|nvim_buf_set_extmark()|:
- Will show up in both |sign-place| and |nvim_buf_get_extmarks()|.
- Are displayed by increasing sign identifier, left to right.
Extmark signs used to be ordered decreasingly as opposed to legacy signs.

When `signcolumn=number` but no sign on a given line has any text,
display the line's line number instead of the (empty) sign text in the
line number column.

Adds support for signs to be 0 cells wide. If all signs of the same
group have no width, the signcolumn will not be rendered for that group.

It is perfectly fine and expected to detach from the screen just by
the UI disconnecting from nvim or exiting nvim. Just keep detach() in
screen_basic_spec, to get some coverage of the detach method itself.
This avoids hang on failure in many situations (though one could argue
that detach() should be "fast", or at least "as fast as resize",
which works in press-return already).
Never use detach() just to change the size of the screen, try_resize()
method exists for that specifically.

* 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: Sign message not translated and inconsistent spacing.
Solution: Add _() for translation. Add a space. (Ken Takata) Also use
MSG_BUF_LEN instead of BUFSIZ.
