files (as opposed to from disk partitions).  This is almost identical to
rawmode, but also knows how to handle inputs that are not a multiple of the
sector size.  Imagezip will pad out the final sector, but uses a special
relocation entry (SHORTSECTOR) to tell imageunzip/frisbee how many bytes
to write in that final sector.

This is "pretty much" backward compatible.  If an old version of imageunzip
encounters the unknown new relocation entry, it will ignore it, resulting
in imageunzip just writing out the additional pad bytes to the output file.
This may or may not screw over the resulting output file.

Also fixed some lint found by GCC 4.2 on FBSD7.

'tables', 'reset', and 'synctables' commands. Rather than assuming all
VLANs live on the One True Experimental Net Stack (unless -S was given),
they all now check the database to see which stack they should be operating
on.

Changed how stack information is currently stored in the database. The
LAN attribute formerly known as 'stack' is now called 'class', and has
two valid values, 'Experimental' and 'Control'. The idea is to record
whether something is an experimental net or control net LAN, not which
specific stack it's on. The 'stack' column in the VLANs table now
records the actual stack_id on which the VLAN has been created.

This is all in support of testbeds that have multiple experimental-net
stacks, as Utah currently does.

look at and use them.

Added optional key/value pairs as parameters for node_type as well. Added 'bgpmux' as a virtualization_type on nodes.

Added a tunnel_netmask attribute to interface_ref elements as a temporary measure to satisfy Georgia Tech.

Added link types to rspec. Removed old link_type attribute. Link types also have parameters which are just key/value pairs which can be anything. For instance, Georgia Tech can use them to encode the key and ttl parameters for EGRE tunnels.

have that information in the widearea_nodeinfo table.

(mostly because of a new bridge device in FBSD).

gracefully handle linux kernels that do not support vers=2.

found in the database, use the stack recorded there.

instead of "Experimental" if the stack cannot be determinted.

stack unless no ports are given. This allows it to be used on other
stacks without passing the -S option. There are probably other commands
that should get this treatment, but being conservative for now.

Also improved the debugging output from commands that complain about
multiple stacks.

Fixed bug in Dave's hacky solution. He was only ever adding the constant 10 rather than the correct parameter value.

handle numbers to be hex strings, but the new delay agent only gives
the netlink pipe class the first qdisc handle, from which the class
infers the rest (we always increment handles by decimal 10 -- i.e.,
190, 200, 210).  So, we have to add 10 decimal in the string, then
convert the string to hex.  Whee!

correct.

in the root context.  Also, give containers CAP_NET_ADMIN so they can
set the per-device txqueuelen via ifconfig.  This may be a bad idea...
but for now it's helpful!

like shared host nodes. These are removed when the experiment swapped
or modified, just like the rest of the virtual state.

on devices they contain.

The xmlrpc logfile was getting left open in children and things were not
being properly background-ed as a result.

Also fix error reported by Mike where pool_daemon fails
if shared-nodes experiment is NEW. Now, daemon exits
silently if the experiment is NEW or SWAPPED.
