Ahelenia Ziemiańska 6af6d22495 perf TUI: Don't ignore job control
In its infinite wisdom, by default, SLang sets susp undef, and this can
only be un-done by calling SLtty_set_suspend_state(true).  After every
SLang_init_tty().

Additionally, no provisions are made for maintaining the teletype
attributes across suspend/continue (outside of curses emulation
mode(?!), which provides full support, naturally), so we need to save
and restore the flags ourselves, as well as reset the text colours when
going under.  We need to also re-draw the screen, and raising SIGWINCH,
shockingly, Just Works.

The correct solution would be to Not Use SLang, but as a stop-gap,
this makes TUI 'perf report' usable.
