Problem: Separate message emitted for each newline present in Lua
print() arguments.
Solution: Make msg_multiline() handle NUL bytes. Refactor print() to use
msg_multiline(). Refactor vim.print() to use print().
Problem: No longer able to show prompt messages with vim.ui_attach().
Solution: Do not execute callback in fast context for prompt message
kinds. These events must be safe to show the incoming message
so the event itself serves to indicate that the message
should be shown immediately.
Problem: Lua callbacks for "msg_show" events with vim.ui_attach() are
executed when it is not safe.
Solution: Disallow non-fast API calls for "msg_show" event callbacks.
Automatically detach callback after excessive errors.
Make sure fast APIs do not modify Nvim state.
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: Ext_messages chunks only contain the highlight attr id, which
is not very useful for vim.ui_attach() consumers.
Solotion: Add highlight group id to message chunks, which can easily be
used to highlight text in the TUI through nvim_buf_set_extmark():
hl_group = synIDattr(id, "name").
Problem: Calling :redraw from vim.ui_attach() callback results in
recursive cmdline/message events.
Solution: Avoid recursiveness where possible and replace global "call_buf"
with separate, temporary buffers for each event so that when a Lua
callback for one event fires another event, that does not result
in invalid memory access.
Problem: Enabling ext_messages claims to set 'cmdheight' to zero, but
only does so for the current tabpage.
Solution: Set stored 'cmdheight' value to zero for all tabpages.
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`.

Also close Nvim instance before removing log file, otherwise the Nvim
instance will still write to the log file.
Also adjust log level in libuv_process_spawn(). Ref #27660

Problem: Peeking and flushing output slows down execution.
Solution: Do not update the mode message when global_busy is set. Do not
flush when only peeking for a character. (Ken Takata)

Problem:
The sleep before collecting the initial screen state is confusing and
may lead to unexpected success if it comes after a blocking RPC call.
Solution:
Remove that sleep and add an "intermediate" argument.
