Problem: Unable to identify legacy signs when fetching extmarks with
`nvim_buf_get_extmarks()`.
Solution: Add "sign_name" to the extmark detail array.
Add some misc. changes as follow-up to #25724

Remove the monolithic Decoration struct. Before this change, each extmark
could either represent just a hl_id + priority value as a inline
decoration, or it would take a pointer to this monolitic 112 byte struct
which has to be allocated.
This change separates the decorations into two pieces: DecorSignHighlight
for signs, highlights and simple set-flag decorations (like spell,
ui-watched), and DecorVirtText for virtual text and lines.
The main separation here is whether they are expected to allocate more
memory. Currently this is not really true as sign text has to be an
allocated string, but the plan is to get rid of this eventually (it can
just be an array of two schar_T:s). Further refactors are expected to
improve the representation of each decoration kind individually. The
goal of this particular PR is to get things started by cutting the
Gordian knot which was the monolithic struct Decoration.
Now, each extmark can either contain chained indicies/pointers to
these kinds of objects, or it can fit a subset of DecorSignHighlight
inline.
The point of this change is not only to make decorations smaller in
memory. In fact, the main motivation is to later allow them to grow
_larger_, but on a dynamic, on demand fashion. As a simple example, it
would be possible to augment highlights to take a list of multiple
`hl_group`:s, which then would trivially map to a chain of multiple
DecorSignHighlight entries.
One small feature improvement included with this refactor itself, is
that the restriction that extmarks cannot be removed inside a decoration
provider has been lifted. These are instead safely lifetime extended
on a "to free" list until the current iteration of screen drawing is done.
NB: flags is a mess. but DecorLevel is useless, this slightly less so

Note: The crash happens in the second test case when using uninitialized
memory, and therefore doesn't happen with ASAN.

Problem: No way to have extmarks automatically removed when the range it
is attached to is deleted.
Solution: Add new 'invalidate' property that will hide a mark when the
entirety of its range is deleted. When "undo_restore" is set
to false, delete the mark from the buffer instead.

While the interfaces for setting number and boolean options are now unified by #25394, there is still a separate `set_string_option` function that is used for setting a string option. This PR removes that function and merges it with set_option.
BREAKING CHANGE: `v:option_old` is now the old global value for all global-local options, instead of just string global-local options. Local value for a global-local number/boolean option is now unset when the option is set (e.g. using `:set` or `nvim_set_option_value`) without a scope, which means they now behave the same way as string options.

`SREQ_*` values are now actual typedef'd enums. `get_option_value_strict()` has also been refactored and split into two functions, `get_option_attrs()` for getting the option attributes, and `get_option_value_strict()` for getting the actual value. Moreover, it now returns an `OptVal`. Other miscellaneous refactors have also been made.

"VimEnter foo" was accepted as a valid event name for "VimEnter".
Events delimited with commas, eg. "VimEnter,BufRead", were also
accepted, even though only the first event was actually parsed.

If you would insert element X at position j, then if you are moving that
same element X from position i < j, you should move it to position j -
1, because you are losing an element.
This error caused a gap to be left in the array, so that it looked like
[x, null, y] instead of [x, y], where len = 2. This triggered #25147.
Fixes: #25147

The removes the previous restriction that nvim_buf_set_extmark()
could not be used to highlight arbitrary multi-line regions
The problem can be summarized as follows: let's assume an extmark with a
hl_group is placed covering the region (5,0) to (50,0) Now, consider
what happens if nvim needs to redraw a window covering the lines 20-30.
It needs to be able to ask the marktree what extmarks cover this region,
even if they don't begin or end here.
Therefore the marktree needs to be augmented with the information covers
a point, not just what marks begin or end there. To do this, we augment
each node with a field "intersect" which is a set the ids of the
marks which overlap this node, but only if it is not part of the set of
any parent. This ensures the number of nodes that need to be explicitly
marked grows only logarithmically with the total number of explicitly
nodes (and thus the number of of overlapping marks).
Thus we can quickly iterate all marks which overlaps any query position
by looking up what leaf node contains that position. Then we only need
to consider all "start" marks within that leaf node, and the "intersect"
set of that node and all its parents.
Now, and the major source of complexity is that the tree restructuring
operations (to ensure that each node has T-1 <= size <= 2*T-1) also need
to update these sets. If a full inner node is split in two, one of the
new parents might start to completely overlap some ranges and its ids
will need to be moved from its children's sets to its own set.
Similarly, if two undersized nodes gets joined into one, it might no
longer completely overlap some ranges, and now the children which do
needs to have the have the ids in its set instead. And then there are
the pivots! Yes the pivot operations when a child gets moved from one
parent to another.

Some more reasonable defaults for topline:
- if topline was replaced with another line, that now becomes topline
- if line was inserted just before topline, display it. This is more
similar to the previous API behavior.

The change in #24824 0081549 was not a regression, however it was an
incomplete change. Unfortunately some common plugins come to depend on
this exising self-inconsistent behavior. These plugins are going to need
to update for 0.10
nvim_buf_set_lines used to NOT adjust the topline correctly if a buffer
was displayed in just one window. However, if displayed in multiple
windows, it was correctly adjusted for any window not deemed the
current window for the buffer (which could be an arbitrary choice if the
buffer was not already current, as noted in the last rafactor)
This fixes so that all windows have their topline adjusted. The added
tests show this behavior, which should be the reasonable one.

Most of the messy things when changing a non-current buffer is
not about the buffer, it is about windows. In particular, it is about
`curwin`.
When editing a non-current buffer which is displayed in some other
window in the current tabpage, one such window will be "borrowed" as the
curwin. But this means if two or more non-current windows displayed the buffers,
one of them will be treated differenty. this is not desirable.
In particular, with nvim_buf_set_text, cursor _column_ position was only
corrected for one single window. Two new tests are added: the test
with just one non-current window passes, but the one with two didn't.
Two corresponding such tests were also added for nvim_buf_set_lines.
This already worked correctly on master, but make sure this is
well-tested for future refactors.
Also, nvim_create_buf no longer invokes autocmds just because you happened
to use `scratch=true`. No option value was changed, therefore OptionSet
must not be fired.

A command typed in the cmdwin and executed with `<CR>` is expected to be
executed in the context of the old curwin/buf, so it shouldn't be changed.

Problem: The result of keytrans() sometimes can't be translated back.

Initially this is just for geting rid of boilerplate,
but eventually the types could get exposed as metadata
|
| |
|
|
|
|
|
| |
This aligns its behaviour better with `nvim_win_close`.
Note that `:hide` is actually incapable of closing the cmdwin, unlike `:close`
and `:quit`, so this is a bit of a difference in behaviour.

Disallow closing the previous window from `nvim_win_close`, as this will cause
issues.
Again, no telling how safe this is. It also requires exposing old_curwin. :/
Also note that it's possible for the `&cmdheight` to change if, for example,
there are 2 tabpages and `nvim_win_close` is used to close the last window in
the other tabpage while `&stal` is 1. This is addressed in a later commit.

Problem: As discussed on Matrix, there was some interest in having
`nvim_open_win` again be able to open floats in the cmdwin (e.g: displaying a
hover doc related to what's in the cmdwin). After #23228, this was disallowed.
Solution: Allow `nvim_open_win` in the cmdwin as long as `!enter` and
`buffer != curbuf` (the former can cause all sorts of issues, and the latter
can crash Nvim after closing cmdwin). Also allow `nvim_win_set_buf` in a similar
fashion.
Note that we're not *entirely* sure if this is 100% safe (cmdwin is a
global-state-using-main-loop-calling beast), but this seems to work OK..?
Also:
- Check the buffer argument of `nvim_open_win` earlier, and abort if it's
invalid (it used to still open a window in this case).
- Untranslate `e_cmdwin` errors in the API (other errors in the API are not
translated: although not detailed in the API contract yet, errors are
supposed to be stable).
