Correct SIGTTIN handling.
In the old TTY layer, SIGTTIN was correctly handled like this:
while (data should be read) {
send SIGTTIN if not foreground process group
read data
}
In the new TTY layer, however, this behaviour was changed, based on a
false interpretation of the standard:
send SIGTTIN if not foreground process group
while (data should be read) {
read data
}
Correct this by pushing tty_wait_background() into the ttydisc_read_*()
functions.
