 Log Message:
 PR/51517: Jay West: Tty settings not restored on exit
 PR/51518: Jay West: prompt is interleaved with client output
 
 Both these issues are caused by rl_restore_handler not DTRT; fix
 it so that it kills the internal libedit state completely. This is
 inefficient, but it works.
 
 Also fix:
 1. add append_history()/H_NSAVE_FP
 2. call the rl_startup_hook before printing the first prompt as documented.
    callint it from rl_initialize breaks python, because the callback ends
    up being invoked before the readline module is installed, and we end up
    dereferencing a NULL pointer.
 3. add el_resize_terminal.
 
 With those changes, s/lreadline/ledit/g in python works.
