for management of shutdown state, XendDomainInfo.refreshShutdown, which is
able to cope whatever the current state of the domain. This fixes bug #124:
running reboot within a domU doesn't bring the domain back up after shutdown,
and bug #256: "xm reboot" could not make domU reboot.
Fix the refreshing inside XendDomain to ensure that the values returned by xm
list reflect reality correctly. We were removing XendDomainInfo instances,
but not creating them on start-up, so if xend were restarted, domain
information was being lost.
Merge XendDomain.dom0_unknown and initial_refresh into
XendDomainInfo.recreate.
Catch exceptions inside callInfo, and reraise them as XendErrors.
Remove unused XendDomain.close.
Further improvements are needed to XendDomainInfo to ensure that it avoids all
race conditions on shutdown, and can cope correctly with xend restarting
during a shutdown.

Now that hotplug seems to be necessary to boot new domains (at least, to
get disk access in those domains), add a note to the installation guide
mentioning this dependency.

The hotplug subsystem is currently needed for block devices to work, as
of changeset 6742:e9d01c5dc7b4d6b7cda9ade0d137ddb89bb204cc. Add a
script to check for the presence of hotplug and warn if it isn't found.

Make xenstored use tdb, transactions can soft-fail (EAGAIN)
Transactions no longer take root dir, no longer lock & block: commit can fail spuriously with EAGAIN, not ETIMEDOUT.
Speeds up transactions by over 1000 times, should be NFS safe.
New program: xs_tdb_dump to dump raw TDB contents.
Don't do failure testing: we are no longer robust against all ENOMEM 8(
Introduce "struct node" which contains perms, children and data.
Make struct xs_permissions unpadded, so we can write to tdb w/o valgrind complaints.
Gently modify TDB to use talloc, not do alloc on tdb_delete.
Fix up transaction users for new semantics.
Don't need a transaction around a single read in xen/i386/kernel/smpboot.c.
Python: transaction_start() returns True/False rather than raising exception on EAGAIN.
Fix usage comment on xs_transaction_end().
Include stdarg to xs_tdb_dump so it compiles.

Fix the use of configuration inside domain_configure. The config written by
XendDomainInfo.sxpr has moved, and this function needs to change to match.
Re-add a call to _add_domain inside domain_restore.
Inside XendDomainInfo.restore, perform the appropriate configuration to restore
the domain.
Validate maxmem_KiB, and cap it at memory_KiB if over that value. Save
requires that value to be correct, as the logic for saving only the pages
in use is not in place inside Xen.
Output the device configuration in sxpr(), as required for save-restore.
Check for image being null when trying to call createDeviceModel -- configure
is called on restore as well as create, and the ImageHandler instance is not
present in the former.
Remove dead code create_blkif.
