dhcpc: Use client IP address as source address for DHCP renew/rebind messages
...
RFC2131 paragraph 4.1 states DHCP messages broadcast by a client prior to
that client obtaining its IP address must have the source IP address
field in the header set to 0.
Request messages transmitted in renewing and rebinding state need to use
the obtained IP address as source IP address in the header; this behavior
lines up with other implementations like ISC dhcp client.

udhcpd: keep expired leases at startup
...
Let udhcpd retain the information about expired leases when restarting
so that the leases are reserved until they possibly become the oldest
expired lease.
This reduces the frequency of IP address changes for example when the
DHCP server and a group of clients, who do not store and request their
previously offered IP address across restarts, are collectively restarted
and the startup order of the clients are not guaranteed.

udhcpc: account for script run time
...
Based on the following user report:
I ran into an issue where I was seeing a long delay in the scripts called
in udhcp_run_script. I was using an old version of OpenWrt (kamikaze)
and a satellite modem. An NTP script was being called and the modem
would sometimes take a long time to respond to the DNS lookup when
it was offline.
This delay started affecting my lease time. The lease that I would
get from my satellite modem before it was online would be short:
only 60 seconds. The delay with NTP and the modem would typically
be about 18 seconds. This would cause the first DHCP renew request
from dhcpc to be a little late. Under certain circumstances,
I could even see the first DHCP renew to occur after the lease
had expired!

udhcpd: add option for tweaking arpping

Some clients have a very short timeout for sending the DHCP
DISCOVER, shorter than the arpping timeout of 2000 milliseconds
that udhcpd uses by default.
This patch allows tweaking the timeout, or disabling of arpping
altogether, at the risk of handing out addresses which are
already in use.

removed all padding from DHCP packets
to fix operation with buggy servers which can't handle

with buggy routers which drop DHCP packets smaller
than 300 bytes (i.e. 342 byte ethernet packets).
Add back some padding to work around.

udhcpc: on SIGUSR1, limit renew attempts time to 20 seconds; then do total reconfig
...
Scenario:
1. udhcpc gets lease for 86400 secs and sleeps for 43200 before renew attempt
2. PC gets physically disconnected and connected to another network
3. some phy control software sends SIGUSR1 to renew the lease, SIGUSR2 isn't
used because newly connected network could be the same as before
4. udhcpc sends unicast renew requests until lease timeout fall to 60 sec.
They are ignored by new network dhcp servers
5. udhcpc sends broadcast rebind requests for 60 seconds, which are NAKed
or ignored too
6. udhcpc deconfigs and starting from discover state, gets new lease for the
new network
So, pt.4+5 it could take up to 86400 secs without correct lease, which is
too long and not acceptable.
Second SIGUSR1 will immediately run into deconfig/discover state, which is
not preferable in case of the same subnet replugged.
This patch makes sure after SIGUSR1 timeout is no more than -A NUM
(usually 20 sec). It means that renew will be requested via broadcast,
and if no replies come back, full deconf/reconf cycle will be initiated
in 20 seconds.
