dhclient - Set state to S_REBOOTING when calling state_reboot().
- Also set state inside state_reboot() to S_INIT when calling
state_init(). Rather than the other way around.
Makes for more consistant idiom and might reduce state confusion.

dhclient - Cancel all timeouts in state_reboot().
- We can get there from any state if a link state change happens.
Fixes a problem where we'd continue to send (corrupted) discover
packets after binding.

- Attempt that nothing accidentally carries over when
a new file (i.e. leases after config) is parsed.
May help with mysterious "Corrupt lease file" messages.

dhclient - Tweak leases file handling.
- Write out new leases file every time a lease is obtained. i.e. don't
append 20 leases before cleaning it up.
- Write new leases file after calling dhclient-script to implement
new info. Gets interface configured first, and makes it more likely
the leases file reflects most current configuration.

dhclient - Sequential options processing more friendly.
- Starting DHCP packet options with DHO_DHCP_MESSAGE_TYPE. Now
DHCP-specific options always come after the option identifying
the packet as DHCP rather than BOOTP. Makes at least Nortel NetIP
DHCP server happier. Clean up some code and parameter passing.
