Problem:
The magic globals `it`, `describe`, etc., are more trouble than they are
worth.
- Hooking into `after_each` requires `getfenv()` hacks.
- They confuse luals/emmylua, because the top-level `.luarc.json` isn't
merged with `test/.luarc.json` (apparently a luals limitation?)
- They totally defeat discoverability because the user just has to
"know" about the various magic symbols.
So they harm DX, which means they serve no purpose at all.
Solution:
- Expose the test API from `testutil`, so tests can call `t.it()`,
`t.describe()`, etc., in the conventional way.
- Drop `getfenv()` hacks.
- Drop the `setfenv()` injection in `load_chunk`.
- Drop `test/_meta.lua`.

…/editor/put_spec.lua:940: in function <…/editor/put_spec.lua:932>
Analysis:
The bell was asserted via the UI 'bell' event (screen.bell), but
vim_beep() rate-limits that to 3 per 500ms. These tests share one
long-lived session, so beeps from earlier tests could exhaust the window
and drop the asserted beep.
Solution:
Use assert_beeps()/assert_nobeep(), which check called_vim_beep (set
before the rate-limit gate).
Problem:
When screen:expect() fails, it renders a snapshot for the error
message. If the grid references a highlight id that was never defined
via "hl_attr_define", the renderer crashes:
screen.lua:1910: attempt to index local 'entry' (a nil value)
This hides the actual failure, and appears "flaky": it only fires on the
failure path, and only when the shared screen is missing an id the grid
still references. A screen created in setup() attaches mid-session, so
highlight ids allocated before it attached (still referenced by stale
grid cells) are never sent to it.
Solution:
- Don't crash while rendering a diagnostic: show undefined highlight ids
as "UNKNOWN_HL_ID(n)", so the real failure and the desync are legible.
- put_spec: fix `visualbell` typo. If it fails again then we can find
the actual root cause.

Problem: feed_command, nvim_buf_set_option, nvim_buf_get_number, and exc_exec
are marked as deprecated.
Solution: Remove them from the test units in api/buffer_spec, autocmd/focus_spec,
ui/input_spec, and editor/put_spec.
Some test units only used a few deprecated functions, so creating a separate PR
for each would be excessive. Therefore, several were combined into a single PR.
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.
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`.
Closes https://github.com/neovim/neovim/issues/27004.
- Close and open a new window each time so that window options have
their default values in each test.
- Change feed_command() to command() as the latter is faster.
Problem: Put in Visual mode cannot be repeated.
Solution: Use "P" to put without yanking the deleted text into the unnamed
register. (Shougo Matsushita, closesvim/vim#9591)

Cherry-pick get_y_previous() and set_y_previous() from patch 8.1.1736.
Nvim has removed y_current, so code related to it is N/A.
Problem:
Subdirectories like "visual", "insert", "normal" encourage people to
separate *related* tests for no good reason. Typically the _mode_ is
not the relevant topic of a test (and when it is, _then_ create
an appropriate describe() or it()).
Solution:
- Delete the various `test/functional/<mode>/` subdirectories, move
their tests to more meaningful topics.
- Rename `…/normal/` to `…/editor/`.
- Move or merge `…/visual/*` and `…/insert/*` tests into here where
appropriate.
- Rename `…/eval/` to `…/vimscript/`.
- Move `…/viml/*` into here also.
