Make HlAttr contain highlighting state for both color modes (cterm and rgb).
This allows us to implement termguicolors completely in the TUI.
Simplify some logic duplicated between ui.c and screen.c. Also avoid
some superfluous highlighting reset events.
Problem: CTRL-G/CTRL-T don't work with incsearch and empty pattern.
Solution: Use the last search pattern. (Christian Brabandt, closesvim/vim#2292)

Problem: Incremental search only shows one match.
Solution: When 'incsearch' and and 'hlsearch' are both set highlight all
matches. (haya14busa, closesvim/vim#2198)

Implement nvim_command_output with `execute({cmd},"silent")`.
Behavior changes:
- does not provoke any hit-enter prompt
- no longer prepends a newline char
- does not capture some noise (like the "[New File]" message, see the
change to tabnewentered_spec.lua)
Technically ("bug-for-bug") this a breaking change. But the previous
behavior of nvim_command_output meant that it probably wasn't used for
anything outside of tests.
Also remove the undocumented `v:command_output` variable which was
a hack introduced only for the purposes of nvim_command_output.

Since "builtin" terminfo definitions were implemented (7cbf52db1b),
the decisions made by tui.c and terminfo.c are more relevant. Exposing
that decision in the 'term' option helps with troubleshooting.
Also: remove code that allowed setting t_Co. `:set t_Co=…` has never
worked; the highlight_spec test asserting that nvim_set_option('t_Co')
_does_ work makes no sense, and should not have worked.
... that does not have that superflous last line.
Also, remove some indeterminism for the freebsd64 tests. Partially,
those were suggested by the tests themselves, while successfull. Some of
them were added after some testing because the lookaround test would
fail on freebsd64 only.
