Problem: [security]: Possible to open more windows into a closing
buffer without splitting, bypassing existing "b_locked_split"
checks and triggering use-after-free
Solution: Disallow switching to a closing buffer. Editing a closing
buffer (via ":edit", etc.) was fixed in v9.1.0764, but add an
error message and check just "b_locked_split", as "b_locked"
is necessary only when the buffer shouldn't be wiped, and may
be set for buffers that are in-use but not actually closing.

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.
