abe8f7515a 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.

ea2b71be66 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.

c29021e2a5 udhcpc: dns labels can actually start with a number 
While RFC1035 recommends a label not to start with a number, there is
actually no such limitation in dns. One may buy a domain name like
0x1.net and use it.

This commit remove this check and allow a user to use such domains.

936c401077 dhcpd: fix an improper widening conversion 
We wanted to detect when tv_sec = unsigned1 - unsigned2
underflows by looking at tv_sec's sign. But if tv_sec
is long and it is wider than unsigned, we get unsigned -> long
conversion which is in this case never negative.

28634924f0 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!

DISCOVER, shorter than the arpping timeout of 2000 milliseconds
that udhcpd uses by default.

This patch allows tweaking the timeout, or disabling of arpping

already in use.

2d576e2a22 udhcpc: make DHCP packets to have at least 300 DHCP bytes 
Commit b8b72f02 removed all padding from DHCP packets
to fix operation with buggy servers which can't handle
maximum sized packets.  But it introduced a regression
with buggy routers which drop DHCP packets smaller
than 300 bytes (i.e. 342 byte ethernet packets).
Add back some padding to work around.

6464f15ddb 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.
