[PATCH 0/3] Some terminal handling TCL

In context of multi-target support, I've been messing around with
GDB's tty / job control handling, the 'terminal ours/inferior'
switching, etc, and staring at gdb/inflow.c a lot. While
adjusting/extending this machinery, the fewer code paths / variants we
have to consider, the better. Hence this precursor series.
Patch #1 removes support for the legacy termio and sgtty terminal
interfaces in favor of assuming termios. I believe that no
gdb-supported system is actually using termio/sgtty today, and so I
believe that this is actually a no-op change.
Patch #2 removes really odd code that doesn't look like have any
reason to exist.
Patch #3 removes a small gdb abstraction over SIGTSTP that hasn't been
useful in decades.
Pedro Alves (3):
Assume termios is available, remove support for termio and sgtty
Don't set terminal flags twice in a row
Eliminate STOP_SIGNAL, use SIGTSTP directly
