src/editline.c:

tty_flush(): Silence compiler warning.

        meta(): Extend to support Home, End and Del keys, in addition to
        the arrow keys. Also capturing PgUp, PgDn and Ins to prevent
        them from generating odd ~ characters in input.

        Also rearranged a couple of callback functions so they could be
        reached by the meta() function without forward declaring them.
        This is also better placement, together with other similar fns.
