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`.
Although `nlua_call_excmd` is semantically for implementing Ex-commands,
the `require()` should never fail, so that's a "Lua error".
But if the call itself fails (the later `semsg` call), that's an "Ex
cmd" error.
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.
Revert the change to do_cmdline_cmd() from #5226.
This function is used in many places, so making it different from Vim
leads to small differences from Vim in the behavior of some functions
like execute() and assert_fails(). If DOCMD_VERBOSE really needs to be
removed somewhere, a do_cmdline() call without DOCMD_VERBOSE is also
shorter than a do_cmdline() call with DOCMD_VERBOSE.
Problem: Ex command error cannot contain an argument.
Solution: Add ex_errmsg() and translate earlier. Use e_trailing_arg where
possible.

Remove duplicate test file 062_tab_pages_spec.lua
Problem:
During a refactor long ago, we changed the `getdigits_*` familiy of
functions to abort on overflow. But this is often wrong, because many
of these codepaths are handling user input.
Solution:
Decide at each call-site whether to use "strict" mode.
