src/bin/sh: input.c jobs.c redir.c redir.h
Log Message:
Keep track of which file descriptors the shell is using for its
own purposes, and move them elsewhere whenever a user redirection
happens to pick the same number. With this we can move the shell
file descriptors back to lower values (be slightly kinder to the kernel)
since we can no longer clash. (Also get rid of a little old unneeded code.)
This also completes the fdflags command, which no longer permits access
to (by way or either obtaining, or changing) the shell's internal fds.
