While `return` and `return nil` are for most intents and purposes
identical, there are situations where they're not. For example,
calculating the amount of values via the `select()` function will yield
varying results:
```lua
local function nothing() return end
local function null() return nil end
select('#', nothing()) -- 0
select('#', null()) -- 1
```
`vim.tbl_get` currently returns both nil and no results, which makes it
unreliable to use in certain situations without manually accounting for
these discrepancies.
Apply semantic token modifiers as separate extmarks with corresponding
highlight groups (e.g., `@readonly`). This is a low-effort PR to enable
the most common use cases (applying, e.g., italics or backgrounds on top
of type highlights; language-specific fallbacks like `@global.lua` are
also available). This can be replaced by more complicated selector-style
themes later on.
Instead of testing for every possible modifier type, only test bits up
to the highest set in the token array. Saves many bit ops and
comparisons when there are no modifiers or when the highest set bit is a
lower bit than the highest possible in the legend on average.
Can be further simplified when non-luaJIT gets the full bit module (see #21222)
The spec indicates that the response may be `null`, but it doesn't
really say what a `null` response means. Since neovim raises an error if
the response is `null`, I figured that ignoring it would be the safest
bet.

Unlike split windows, creating a new floating window does not cause
other windows to resize, so it doesn't make much sense to trigger
WinScrolled or WinResized when creating a new floating window.
1. The algorithm for applying edits was slightly incorrect. It needs to
preserve the original token list as the edits are applied instead of
mutating it as it iterates. From the spec:
Semantic token edits behave conceptually like text edits on
documents: if an edit description consists of n edits all n edits are
based on the same state Sm of the number array. They will move the
number array from state Sm to Sm+1.
2. Schedule the semantic token engine start() call in the
client._on_attach() function so that users who schedule_wrap() their
config.on_attach() functions (like nvim-lspconfig does) can still
disable semantic tokens by deleting the semanticTokensProvider from
their server capabilities.
Problem: `chansend()` on Windows sends lines in reverse order.
Cause: Using \n instead of \r\n for newlines on Windows.
Solution: on Windows, use CRLF newline characters.
Fixes#18501
Problem: Using freed memory with the cmdline popup menu.
Solution: Clear the popup menu when clearing the matches. (closesvim/vim#11677)

groundwork for this feature and for their work on some of the helper
utility functions and tests
`willSaveWaitUntil` allows servers to respond with text edits before
saving a document. That is used by some language servers to format a
document or apply quick fixes like removing unused imports.
Problem: WinScrolled is not triggered when filler lines change.
Solution: Add "topfill" to the values that WinScrolled triggers on.

Problem: test/functional/ui/screen.lua would be reloaded for each
*_spec.lua file, which causes an extra nvim session to be started
to get the color map each time.
solution: Mark screen.lua as a preloaded file, but defer the
loading of the color map to the first time Screen object is initialised.
Problem: Not enough folding code is tested.
Solution: Add more test cases. (Yegappan Lakshmanan, closesvim/vim#8046)
