<Paste> is a 3-byte sequence and the beginning one or two bytes can appear at
the very end of the typeahead buffer. When this happens, we were exiting from
`vgetorpeek()` instead of reading more characters to see the complete sequence.
I think this should fix#7994 -- at least partially. Before this change, when I
paste exactly 64 characters into a freshly booted instance, I get what I pasted
plus the literal text "<Paste>" at the end. Nvim also stays in nopaste mode.
The attached test case fails in this manner without the code change.
Fix#7994
Problem: When we changed startup to wait for the TUI (like a remote UI),
we forgot to set os/input.c:global_fd. That used to be done by
input_start().
Solution: Initialize os/input.c:global_fd before initializing libtermkey
(termkey_new_abstract) so that tui_get_stty_erase() and
friends can inspect the correct fd.

The test.functional.helpers and test.unit.helpers modules now include
all of the public functions from test.helpers, so there is no need to
separately require('test.helpers').
Previously, ordinary redraws were missing from terminal mode. Instead,
there was an async callback that invoked update_screen() on terminal
data regardless of mode (as if :redraw! was invoked by a timer).
This created some issues:
- async changes to an unrelated ordinary buffer were not always redrawn in
terminal mode
- screen cursor position was not properly updated in terminal mode (partial
fix, will be properly fixed in a follow up PR)
- ad-hoc logic was needed for interaction with special states such as
inccommand or horizontal wildmenu.
Instead redraw terminal mode just like any other state. This disables forced
redraws in cmdline mode, which were inconisent which async changes to
normal buffers (which are not redrawn in cmdline mode).
Before now, Nvim always degrades UI capabilities to the lowest-common
denominator. For example, if any connected UI has `ext_messages=false`
then `ext_messages=true` requested by any other connected UI is ignored.
Now `nvim_ui_attach()` supports `override=true`, which flips the
behavior: if any UI requests an `ext_*` UI capability then the
capability is enabled (and the legacy behavior is disabled).
Legacy UIs will be broken while a `override=true` UI is connected, but
it's useful for debugging: you can type into the TUI and observe the UI
events from another connected (UI) client. And the legacy UI will
"recover" after the `override=true` UI disconnects.
Example using pynvim:
>>> n.ui_attach(2048, 2048, rgb=True, override=True, ext_multigrid=True, ext_messages=True, ext_popupmenu=True)
>>> while True: n.next_message();
Problem: Using `:stopinsert` while in normal mode in a terminal buffer
prevents neovim from entering insert mode.
Solution: Move `stop_insert_mode = false` from terminal_check to
terminal_enter to be consistent with edit.c, as suggested by bfredl in
#9889.
Closes https://github.com/neovim/neovim/issues/9889.
Problem: Calling :stopinsert from RPC while in terminal-mode does not
go back to normal-mode.
Solution: Implement a check() handler for state_enter(), adapted from
insert_check().
Fix#7807
Previous approach skipped the test if the expected value matched the
default value ("dark"). New approach always checks, but uses retry() to
ignore potentially wrong 'background' before the terminal response is
handled.
If terminal response is received during startup, set 'background' from
a nested "one-shot" (once) VimEnter autocmd.
The previous not-so-clever "self-rescheduling" approach could cause
a long delay at startup (event-loop does not make forward progress).

Problem: Relative cursor position is not calculated correctly.
Solution: Always set topline, also when window is one line only.

- Like Vim, use set_option_value() followed by reset_option_was_set().
- Do not use set_string_default(), so the default is predictable.
This affects `:set bg&`.
- Wait until end-of-startup (VimEnter) to handle the response. The
response is racey anyways, so timing is irrelevant. This allows
OptionSet to be triggered, unlike during startup.
Makes the 'scrollback' option more consistent (same default for all buffers) and future-proof.
- Default to -1 for all buffers, but treat it as an implementation detail.
- Document range of 1 - 100_000.
- New terminal buffer by default sets scrollback=10_000 if the global default is -1.
- Existing terminal buffer: On entering terminal-mode or on refresh, if the user explicitly did `:set[local] scbk=-1`, the local value goes to 100_000 (max). (This is undocumented on purpose. Users should work with explicit values in the range of 1-100_000.)
- Avoid using platform-specific shell, it failed in MINGW_64 env.
- tty-test.c echos our input, which is exactly what we need for this test.
- Test fails correctly if 894f6bee54 is reverted.
wp->w_height_inner now contains the "inner" size, regardless if the
window has been drawn yet or not. It should be used instead of
wp->w_grid.Rows, for stuff that is not directly related to accessing
the allocated grid memory, such like cursor movement and terminal size
By historical accident, Nvim defaults to background=light. So on a dark
background, `:colorscheme default` looks completely wrong.
The "smart" logic that Vim uses is confusing for anyone who uses Vim on
multiple platforms, so rather than mimic that, pick the (hopefully) most
common default.
- Since Neovim is dark-powered, we assume most users have dark backgrounds.
- Most of the GUIs tend to have a dark background by default.

- window_split_tab_spec.lua: Put cursor at bottom of :terminal buffer so
that it follows output.
- inccommand_spec.lua: Increase timeout to allow 2nd retry.
- Timer tests are less reliable on Travis CI macOS 10.12/10.13.

Add ext_newgrid and ext_hlstate extensions. These use predefined
highlights and line-segment based updates, for efficiency and
simplicity.. The ext_hlstate extension in addition allows semantic
identification of builtin and syntax highlights.
Reimplement the old char-based updates in the remote UI layer, for
compatibility. For the moment, this is still the default. The bulitin
TUI uses the new line-based protocol.
cmdline uses curwin cursor position when ext_cmdline is active.
Show a proper confirmation dialog when trying to unload a terminal buffer while
the confirm option is set or when :confirm is used.
