* Avoid performance problems with setbufline() and Treesitter
Call nvim_buf_set_lines() instead.
Since this is a performance problem only in Neovim (Treesitter is only
available there), it doesn't matter that this API is unavailable in Vim.
Note: nvim_buf_set_lines() returns E5555, when set nomodifiable is on.
Fixes#3669
* Avoid sign flickering
The signs flickered because nvim_buf_set_lines() removes all signs from
lines that it touches, which will immediately be readded by Ale (causing
the brief flicker). This is intended behaviour in neovim [0].
Neovim itself faced this problem in their own LSP formatting sync,
although they had the problem with marks instead of signs [1].
Similar to how neovim fixed it by storing and restoring the marks [2],
we can do the same thing with signs.
In fact it is easier with signs, because sign_placelist() will just
ignore and skip invalid line numbers, so we don't need to filter signs
that are not valid anymore.

* Remove virtual text via types-filter
This is more robust and has the additional sideeffect that it will make
it easier to implement showing virtual text for all warnings
simultaneously.
We definitely do not want to do a call to prop_remove() for every
virtual text as that will cause noticeable lag when many warnings are
present, thus we can use this to remove all virtual text lines with one
call in the future.

* Allow virtual text to appear for all warnings of the buffer
This can be enabled with:
let g:ale_virtualtext_cursor = 2
It is implemented both for neovim and vim 9.0.0297.
Note that sometimes it may appear like some warnings are displayed
multiple times. This is not a bug in the virtual text implementation,
but a sideeffect of multiple linters returning similar results.
For example for Rust, the 'cargo' and 'rls' linters appear to be
activated at the same time, but they sometimes return identical errors.
This causes the virtual text to show the same warning twice.
In the future we can mitigate this problem by removing duplicate errors
from our internal location list.
However users can also achieve cleaner warnings simply by activating
only one linter for each language (or multiple unambiguous linters).
For example for Rust, the problem could be solved with:
let g:ale_linters = {'rust': ['analyzer']}

Regression was introduced in d93bc2baf7
The problem was that we did not handle the edge case where there is no
last popup to close, which caused old vim versions to enter code by
accident that was only supposed to be run by vim 9.
We fix this by guarding the if condition for vim 9.
Fixes#4290
Our current virtual text implementation for vim emulates it by abusing
the textprop and popupwin feature from vim 8.2 (for more details see
commit 708e810414).
This implementation sometimes is janky, for example the popups may leak
into other vim windows next to the current window.
Luckily, vim just got native virtual-text support as a proper subtype to
the prop_add() function. By using the 'text' option, the text property
automatically becomes virtual text that is appended to the current line
if col is zero.
Note that the prop_add() method now returns negative IDs for virtual
text properties.
This feature was added in vim 9.0.0067, but it got a lot of bugfixes
which is why we only use this new API if vim has at least version
9.0.0214.
However, there are still some minor bugs with vim's native virtual text,
so we might have to bump the version check again in the future.
Also see #3906.
Now with proper virtual text support for both vim and neovim available,
we can tackle #2962 in the future by simply tracking multiple virt-texts
instead of just the last one.
In the future we might also want to disable our virtual text emulation
support for vim, as it is a total hack, but for now we should keep it
for backwards compatibility.
If virtualtext.vim is autoloaded first, it will link
ALEVirtualTextWarning to ALEWarning. But ALEWarning is not initialized
yet, so it will create ALEWarning, but with no color definition set.
Shortly after, highlight.vim is autoloaded, which would usually link
ALEWarning to SpellCap, but only if ALEWarning is not already set.
However since ALEWarning is already initialized due to the previous
link, we skip this and never actually come around to properly
initializing it.
We fix this by initializing all highlight groups in highlight.vim, thus
satisfying the dependency of ALEVirtualTextWarning being initialized
after ALEWarning.
Fixes#3585
There is no need to filter for references in such a complicated way.
docker images already works if you just pass the image and tag as
an argument.
This caused problems if one was using podman with its docker-compatible
interface.
Previously podman would return the following error:
Error: cannot specify an image and a filter(s)
With this new method podman does not return an error anymore, causing
the image to not be redownloaded every time and it still works with
normal Docker.
Before this patch multiline warnings would appear in a single line with
'^@' as separator.
Now we use whitespace as separator to improve the appearance.
Also strip trailing whitespace, newlines, etc...
