Packing and unpacking return values impairs performance considerably.
In an attempt to avoid creating tables as much as possible we can
instead pass return values between functions (which does not require
knowing the number of values a function might return). This makes the
code more complex, but improves benchmark numbers non-trivially.
fix(extmarks): disallow removing extmarks in on_lines callbacks
decor_redraw_start (which runs before decor_providers_invoke_lines) gets
references for the extmarks on a specific line. If these extmarks are
deleted in on_lines callbacks then this results in a heap-use-after-free
error.

Problem: no functions for converting from/to UTF-16 index.
Solution: Add UTF-16 flag to existing funtions and add strutf16len() and
utf16idx(). (Yegappan Lakshmanan, closesvim/vim#12216)

Problem: Tee-Object does not create a file if it does not receive input
for example when :grep does not find matches.
and so nvim tries to open a nonexistent errorfile causing an error.
Solution: use tee.exe instead of Tee-Object
This was originally meant as a convenience but prevents possible
functionality. For example:
-- Get the keys of the table with even values
local t = { a = 1, b = 2, c = 3, d = 4 }
vim.iter(t):map(function(k, v)
if v % 2 == 0 then return k end
end):totable()
The example above would not work, because the map() function returns
only a single value, and cannot be converted back into a table (there
are many such examples like this).
Instead, to convert an iterator into a map-like table, users can use
fold():
vim.iter(t):fold({}, function(t, k, v)
t[k] = v
return t
end)
Problem: There is no way to get a list of swap file names.
Solution: Add the swapfilelist() function. Use it in the test script to
clean up. Remove deleting individual swap files.

vim-patch:9.0.1005: a failed test may leave a swap file behind
Problem: A failed test may leave a swap file behind.
Solution: Delete the swap file to avoid another test to fail. Use another
file name.

Remove FUNC_ATTR_UNUSED from eval functions as fptr is always unused.
Co-authored-by: Bram Moolenaar <Bram@vim.org>
vim.iter wraps a table or iterator function into an `Iter` object with
methods such as `filter`, `map`, and `fold` which can be chained to
produce iterator pipelines that do not create new tables at each step.
- vim.diagnostic.config() now accepts a function for the virtual_text.prefix
option, which allows for rendering e.g., diagnostic severities differently.
Problem: Only created files can be cleaned up with one call.
Solution: Add flags to mkdir() to delete with a deferred function.
Expand the writefile() name to a full path to handle changing
directory.

feat(lua)!: add stricter vim.tbl_islist(), rename vim.tbl_isarray()
Problem: `vim.tbl_islist` allows gaps in tables with integer keys
("arrays").
Solution: Rename `vim.tbl_islist` to `vim.tbl_isarray`, add new
`vim.tbl.islist` that checks for consecutive integer keys that start
from 1.
* feat(lua): vim.tbl_contains supports general tables and predicates
Problem: `vim.tbl_contains` only works for list-like tables (integer
keys without gaps) and primitive values (in particular, not for nested
tables).
Solution: Rename `vim.tbl_contains` to `vim.list_contains` and add new
`vim.tbl_contains` that works for general tables and optionally allows
`value` to be a predicate function that is checked for every key.
Using :CheckHealth invokes an error, and many of the features from :checkhealth
doesn't even work such as calling only a specific check. Users should use
:checkhealth instead.
Vimball is an outdated feature that is rarely used these days. It is not
a maintenance burden on its own, but it is nonetheless dead weight and
something we'd need to tell users to ignore when they inevitably ask
what it is.
