        src/lib/libedit/readline: readline.h

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.
