Rename getdata macro to listgetdata.

ALL_LIST_ELEMENTS, new macro, forward-referencing macro for use

Add ALL_LIST_ELEMENTS_RO for cases which obviously do not need the
"safety" of previous macro.
LISTNODE_ADD and DELETE macros renamed to ATTACH, DETACH, to
distinguish from the similarly named functions, and reflect their
effect better.

IFINDEX_INTERNAL.
(zebra_interface) Check return code from interface_cmd.func.
Do not set internal ifindex values to if_new_intern_ifindex(),

all internal interfaces now have ifp->ifindex set to IFINDEX_INTERNAL.
* rt_netlink.c: (set_ifindex) New function used to update ifp->ifindex.

(netlink_interface, netlink_link_change) Call set_ifindex to update

IFINDEX_INTERNAL 0, since all internal (i.e. non-kernel) pseudo-

of if_delete, since it is generally not safe to remove interface
structures. After deleting, set ifp->ifindex to IFINDEX_INTERNAL.
(zebra_interface_if_lookup) Tighten up code.
* ospf6_zebra.c: (ospf6_zebra_if_del) Previously, this whole function
was commented out. But this is not safe: we should at least update
the ifindex when the interface is deleted. So the new version
updates the interface status and sets ifp->ifindex to
IFINDEX_INTERNAL.

(vty_flush) When vty->lines is 0, call buffer_flush_available instead
of buffer_flush_window. Look at the return code from buffer_flush
to detect I/O errors (and in that case, log an error message and
close the vty).
(vty_create) Fix scope to static. Initialize sb_len to 0 instead
of creating sb_buffer.
(vty_accept) Set socket nonblocking.
(vtysh_accept) Use new set_nonblocking function instead of calling
fcntl directly.
(vtysh_flush) New function called from vtysh_read (after command
execution) and from vtysh_write. This flushes the buffer
and reacts appropriately to the return code (by closing the vty
or scheduling further flushes).
(vtysh_read) Check whether error is fatal using ERRNO_IO_RETRY.
If not, just try again later. Otherwise, call buffer_reset before
calling vty_close (to avoid trying to flush the buffer in vty_close).
Fix logic to allow case where a command does not arrive atomically
in a single read call by checking for the terminating NUL char.
(vtysh_write) Use new vtysh_flush helper function.
(vty_close) No need to call buffer_empty, just call buffer_flush_all
in any case (it will check whether the buffer is empty).
Do not free sb_buffer (since it has been removed).
(vty_log_fixed) Use writev instead of write.
