c/s 20393 breaks existing domain configuration that contains
spaces in the vbd path name. Fixed by this trivial patch which
provides missing quotes.

The failure to read "backend/tap/<domid>/*" in the xenstore is a usual
case since the domain is gone after xenstore-ls command is executed.
The error should be ignored.

- Use the device and inode information provided by losetup to find
if the vbd backing file is in use on another vbd.
- Use losetup to find a free loopback device.

Avoid races between hotplug "add" and "remove" leading to "leaked"
loopback devices.
- Don't setup loopback device if xend is no longer waiting for the
vbd.
- Use the lock file to avoid add/remove races.

- Have the buid system generate a file which exports the install paths
for the hotplug scripts and stubdom / stubdom-dm
- Move file generation code from tools/python/Makefile into a gmake
macro
in Config.mk to avoid maintenance of three duplicates each with its
own
tweaks and bugs
- Export gmake variables into ioemu as shell variables
for upcoming ioemu patches
- Do above as a gmake macro to avoid maintenance of several duplicates
- Adjust hotplug scripts to find the right xen binaries from the
install directory
- Adjust stubdom-dm to use the install directories

Allow 'file' based disks, that are blkback based disks, to be shared
between the guest domain and the stubdom. It does so exploiting the
same exception introduced in the previous patch "stubdoms phy disks
sharing". Now we can remove the hack in stubdom-dm that forces "file"
disks to be opened using blktap instead of blkback.
