Add a UserInterface::is_ok method and return false on
SIGHUP/stdin closing/socket dropping
This should be cleaner and more robust than the previous SIGHUP
handling code.
Fixes#1594
Instead of using two vectors, we can hold both current and next
threads in a single buffer, with stacks growing on each end.
Benchmarking shows this to be slightly faster, and should use less memory.
Remove ExecState to store threads inside the ThreadedRegexVM so that
memory buffers can be reused between executions. Extract an ExecConfig
struct with all the data thats execution specific to avoid storing
it needlessly inside the ThreadedRegexVM.
even though tmux 2.7 is installed.
The problem is that
```
expr "$(tmux -V)" : 'tmux \([0-9]*\|master\)'
```
fails on FreeBSD. It works fine with GNU expr.
Replace the expression with cut(1) and a simple parameter expansion
which should hopefully work fine on any POSIX system.

If the local client was quitted during its creation (using -e quit
for example), we could have been accessing a null pointer afterwards.
Make the rest of the code aware that local_client might be null.

I've just committed a FreeBSD port of kakoune to the ports tree [1]. A binary package should also be available in the next couple of days.
It would be nice if it could be mentioned in the README.
Thank you :)

Shifted function keys are not well standardized around terminals,
Shift F(N) usually returns F(X) + N, with X=12 on xterm, X=10 on
rxvt-unicode... Default to X=12 and make it configuable through
the ncurses_shift_function_key ui_option.
This fixes what #1898 tried to.
Because keyboard layouts vary, the shift-modifier `<s-…>` is only supported
for special keys (like `<up>` and `<home>`) and for ASCII lowercase where
we assume the shift-modifier just produces the matching uppercase character.
Even that's not universally true, since in Turkish `i` and `I` are not an
uppercase/lowercase pair, but Kakoune's default keyboard mappings already
assume en-US mappings for mnemonic purposes.
Mappings of the form `<s-x>` are normalized to `<X>` when `x` is an ASCII
character. `<backtab>` is removed, since we can now say `<s-tab>`.
