Pedro Alves 268a799a45 Make stdin be per UI
This commit makes each UI have its own "stdin" stream pointer.  This
is used to determine whether the "from_tty" argument to
execute_command, etc. should be true.

Related, this commit makes input_from_terminal_p take an UI parameter,
and then avoids the gdb_has_a_terminal in it.  gdb_has_a_terminal only
returns info on gdb's own main/primary terminal (the real stdin).
However, the places that call input_from_terminal_p really want to
know is whether the command came from an interactive tty.  This patch
thus renames input_from_terminal_p to input_interactive_p for clarity,
and then makes input_interactive_p check for "set interactive" itself,
along with ISATTY, instead of calling gdb_has_a_terminal.  Actually,
quit_force wants to call input_interactive_p _after_ stdin is closed,
we can't call ISATTY that late.  So instead we save the result of
ISATTY in a field of the UI.
