Nvim (tui.c) always enables SGR mouse (TUIData.unibi_ext.enable_mouse).
But if libtermkey sees key_mouse (kmous) in terminfo its terminfo driver
(driver-ti.c) will be activated, which by accident only supports X10
protocol. The libtermkey CSI driver (driver-csi.c), in contrast,
supports SGR.
We can force libtermkey to ignore the terminfo key_mouse entry by
returning NULL in the tui_tk_ti_getstr hook. That forces the CSI driver.
What is the effect of returning NULL from `tui_tk_ti_getstr()`?
- libtermkey `driver-ti.c:load_terminfo()` skips the entry.
- `termkey.c:peekkey()` iterates through all drivers, it finds
`TERMKEY_RES_NONE` for the ti driver and falls back to the CSI driver.
On some versions of macOS, pbcopy doesn't work in tmux <2.6

Fallback to tmux in that case.
Add a healthcheck for this scenario.

Per CMAKE docs, CMAKE_HOST_SYSTEM_VERSION is the result of `uname -r`:
https://cmake.org/cmake/help/v3.4/variable/CMAKE_HOST_SYSTEM_VERSION.html?highlight=uname
A numeric version string for the system. On systems that support
uname, this variable is set to the output of uname -r. On other
systems this is set to major-minor version numbers.
On Windows it is something like "6.1", so it won't match ".*-Microsoft".
Closes#7329
Problem: When 'wildmenu' is set and 'wildmode' has "longest" then the first
file name is highlighted, even though the text shows the longest
match.
Solution: Do not highlight the first match. (LemonBoy, closesvim/vim#1602)

Vim's src/testdir has more directories in it, so the "./samples/" item
happens to have a space in front of it. This isn't relevant to the
test, so just elide the space for our case.
This reverts commit f7fe3012204169f22412194a78f196ffc72bb8c3.
Fails on QuickBuild because it uses a non-local path.
Need a environment-agnostic solution
ui_bridge:ui_bridge_stop() calls ui_detach_impl() last, so the check for
ui_active() in ui:ui_refresh() doesn't help: tui_main() already freed
the `ui` object.
There is a race between ui_bridge_stop (thread T0) and tui_main (thread T1).
UIBridgeData.stopped could be set while ui_bridge_stop() is in the
middle of loop_poll_events(), which may invoke tui_scheduler() on T0.
The pointers in tui_scheduler() may be invalid by then.
Solution(?): Use the `UI.data` field as a "stopped" flag and check it in
tui_scheduler().

tui: fix use-after-free: swap in empty scheduler
This should make life easier for UIs like VimR which implement their own
in-process bridged UI: they don't need to worry that their `scheduler`
might receive an invalid pointer.
To avoid that, ui_bridge_stopped() swaps in an empty scheduler. Note
that this requires the call to loop_poll_events() to be moved into the
critical section.

We were initially checking whether to apply 'langmap' translation based
on typebuf.tb_maplen.
This gets set to 0 on the last byte of a map when the del_typebuf()
function is called, which means that the option was not working for the
last character of a mapping.
For this reason, we switched to using KeyTyped to decide whether to
apply the transformation or not in commit 53da57d27.
Substituting one for the other isn't enough, because KeyTyped isn't set
until vgetorpeek() is returning.
This means 'langmap' translations are not applied when searching for
characters to map in the vgetorpeek() function if the *previous* key was
not typed.
We can't assert that both hold, as we would then *not* apply the
transformation when looking for a map starting with the first typed key
after a previously expanded map (as KeyTyped would be `false` from the
previously expanded map, and not yet reset).
Hence we assert that if we are looking for the mapping while in
vgetorpeek(), the map length should be zero, otherwise, KeyTyped must be
`true`.
This is implemented by checking for the variable `vgetc_busy`.
