slivers can store/return error info to the user in sliverstatus.
This include the top level aggregate for a slice.

Added an 'error' attribute to the top level sliverstatus return hash,
to return this error.

Put start/restart sliver into the background so that it runs async,
just like it does when invoked from the CreateSliver() path. This is
because start/restart can take an arbitrary length of time, and having
the RPC sit in hold for that long is not an ideal interface. Users can
get all the info they need from the sliverstatus call.

Change Start/Restart so that all of the error message we were printing
to STDERR for the mail log, also go back to the user in the toplevel
error for the aggregate.

top level error info for later return. This allows non-node slivers to
return useful info in sliverstatus.

Since the interface names in the solution do not match the interface names on the request, we can't correlate them anyhow. Reverting to just v1 processing until we move libvtop to outputting rspecv2

Testing this tool also allowed me to find some typos in the delaylink example.

Also, reordered initialization of counters so it is the same as the order of the access methods for easier verification that everything gets initialized.

manifest updated with new interfaces in the nodes section.

What you cannot do, is change the endpoint of an existing link. For
example, if link0 goes from A to B, you cannot submit an rspec that
changes link0 to go from A to C. What you *can* do is submit an rspec
that removes link0 and adds link1 from A to C. This was not working
before, for a number of reasons having to do with the manifest
generation, but those are all fixed now.

This reverts commit e9ed9bcd.
Apparently the mapper.in part breaks something.

We don't officially support this anymore, but the problems were minor:

mapper: use HAVE_XERCES to determine whether rspec v2 output is supported.
The symptom is that swapin will fail due to passing the unsupported 'f'
option to assign, but it just isn't going to work anyway without an XML
parser installed.

rc.mkelab: fix a broken version check that would lead to inner-boss
setup failure on a pre-FreeBSD7 machine.

scriptlock to ensure that only one ptopgen runs at a time. Any other
requests that come along while ptopgen is running, queue up and wait
for it to finish, and then return the same results (shared via a file
in /var/tmp).

concatenated without a space.

This forces imagehash to hash pieces on aligned sector boundaries rather
than just doing it from the start of each chunk. Result now is that there
may be a partial hash piece at the beginning of each range and another
partial piece at the end. Ideally, we would avoid those partial pieces,
but we are only using this as a point of comparison right now.

Scroll doesn't zoom map when mouse is over an info window. Slices in the map legend update with status and when selected. Added buttons to refresh slice, slices or everything. Fixed offline support. Added ability to use cache when logged in to use cached managers but live data for everything else.

Randomized exponential backoff on busy. Shows spinner until Slice has been created and status has been determined.  Sends full RSPEC to all managers. If a CreateSliver? fails, the others will not be cancelled. Give user more feedback on errors during slice creation. RSPEC now included along with the XML-RPC call in log messages.

Redeem fails. This was causing ReleaseTicket() failures later.

first arg, so all other args off by one. This stuff would never have
worked right.
