b8a53fb638 Don't assume the shell's controlling terminal is attached to file descriptor 
2. Instead, open /dev/tty. This problem stopped commands in subshells from
being executed correctly if standard error was redirected.

b6bd829347 Remove support for the "old" tty driver by unifdef -UOLD_TTY_DRIVER; 
many other parts of the shell are no longer compatible with this, and it
makes jobs.c quite cluttered with #ifdef's.

7e9561b97a Instead of keeping just the jobid of the most recently bg'd or fg'd job,

to support the idea of `previous job', and to allow the jobs fg and bg
default to be correct according to POSIX.
