Add a function 'ipcalc' to /lib/functions.sh that sets variables more
safely using export.
With this new function, dnsmasq also handles the return value of ipcalc
correctly.

Checking whether /sbin/udhcpc is a symbolic link breaks using the
DHCP proto handler inside procd-ujail where bind-mounts are used for
the resolved link. Check whether /sbin/udhcpc is executable instead
to allow using the proto handler for DHCP-provisioned containers.

Placeholder DHCP user scripts were added recently.
These files make package-based installations of such scripts more difficult.
Pull user callbacks from directories instead to allow packages and users to

Certain DHCP servers push a gateway outside of the assigned interface subnet,
to support those situations, install a host route towards the gateway.
If Gateway and IP are served in same network, openwrt quagga cannot learn

working fine when Gateway and IP are in different network.

This option, defined by RFC3442, allows a DHCP server to send static
routes to a client. But the client has to request this option
explicitely.
Static routes are useful when the gateway configured by DHCP cannot be
in the same subnet as the client. This happens, for instance, when
using DHCP to hand out addresses in /32 subnets.
A new configuration option "classlessroute" is available, allowing
users to disable this feature (the option defaults to true).
Other DHCP clients already request this option by default (dhcpcd, for
instance, and possibly Windows). If a DHCP server does not support
this option, it will simply ignore it.

Commit ce92f6650bd8a86db04c7a6cbb58e7fdb200a7e6 added source IP support
for DHCP default routes. As a side effect of this change the default route
could be present twice in netifd (once with source IP set and once with
source IP unset) if it was sent by the server in both the router and static
route options. Therefore add source IP support as well for static routes as this
case was not considered. Additional remove unused parameter type.
