c850c0eec5 Restore common/discover.c, common/options.c and server/dhcp.c 
as I mistakenly committed them to head instead of the ticket
branch.

640101e3d3 Correct an unsigned math operation when calculating the options 
buffer space for bootp and use a better constant - DHCP packet
size instead of DHCP packet size + udp and iP headers.
Check that we have a packet->options structure before using it.
Only process packets that are longer than a bootp fixed packet
including server and file names.  Previously we allowed for
shorter packets but that wasn't working and nobody noticed.

1e05d095c2 Don't include lease time information in the response to a DHCPINFORM 
request.  We do this by removing any time information from the option
cache before building the reponse packet.  Bug ticket 21092.

f4534b17fa - Fixed a cosmetic bug where pretty-printing valid domain-search options would 
result in an erroneous error log message ('garbage in format string').

47e6eb82cb - The notorious 'option <unknown> ... larger than buffer' log line, 
which is seen in some malformed DHCP client packets, was modified.
  It now logs the universe name, and does not log the length values
  (which are bogus corruption read from the packet anyway).  It also
  carries a hopefully more useful explanation. [ISC-Bugs #18241]

20210a7bfc Clients that sent a parameter request list containing the routers option

8269561daa - A bug was fixed where the length of a hostname was miscalculated, so that 
hosts were given odd-looking domain names ("foo.bar.ba.example.com").

bead14ea8b - The server will now include multiple IA_NA's and multiple IAADDRs within 
them, if advertised by the client.  It still only seeks to allocate one
  new address. [ISC-Bugs #17254]

e2624b82f1 - Reworked cons_options() and store_options() to fix a buffer 
overflow that could result in a DoS (CVS 2007-0062).  Also general
  code tidying. [rt17090]
- Also fixed a spurious error message on the client. [rt17250]

e9c596456f - The subnet-mask option inclusion now conforms with RFC2132 section 3.3; 
it will only appear prior to the routers option if it is present on the
  Parameter-Request-List.  The subnet-mask option will also only be
  included by default (if it is not on the PRL) in response to DISCOVER
  or REQUEST messages.
  [ISC-Bugs #17117]
- The FQDN option is only supplied if the client supplied an FQDN option or
  if the FQDN option was explicitly requested on the PRL.

a512d11b6d - Corrected some situations where variables might be used without being 
initialized. [ISC-Bugs #16865]

- Silenced several other compiler warnings. [ISC-Bugs #16865]

- Include the more standard sys/uio.h rather than rely upon other header
  files to include it (fixes a BSDI compile failure). [ISC-Bugs #16865]

b543fea9d4 - A new common configuration executable statement, execute(), has been 
added.  This permits dhcpd or dhclient to execute a named external
  program with command line arguments specified from other configuration
  language.  Thanks to a patch written by Mattias Ronnblom, gotten to us
  via Robin Breathe. [ISC-Bugs #13728]

f7fdb21693 - Varying option space code and length bit widths (8/16/32) are now 
supported.  This is a milestone in acheiving RFC 3925 "VIVSO" and
  DHCPv6 support. [ISC-Bugs #15979]

ee91252816 - The subnet-mask option is now supplied by default, but at lowest 
priority.  This helps a small minority of clients that provide parameter
  request lists, but do not list the subnet-mask option because they were
  designed to interoperate with a server that behaves in this manner.
  [ISC-Bugs #1196]
- The FQDN option is similarly supplied even if it does not appear on the
  parameter request list, but not to the exclusion of options that do
  appear at the parameter request list.  Up until now it had ultimate
  priority over the client's parameter request list.  [ISC-Bugs #1196]
