Roger Pau Monne 331f2c59fd libxl: handle the return value of wait_for_dev_destroy select
Handle the return value of the select call inside wait_for_dev_destroy
properly, and return 0 if a device is removed, or ERROR_* if a timeout
or error happened. Use the return value of wait_for_dev_destroy inside
libxl__device_remove to properly return from that function.

Philipp Hahn 93bf609a77 pygrub: Add HybridISO support for PyGrub2
grub-mkrescue internally uses xorriso, which generates a so-called
"Hybrid ISO": The ISO images also contains a DOS partition table,
which allows the identical ISO file to be stored on an USB stick for
booting from it. This breaks PyGrub, since it (wrongly) detects only
the DOS partition table and uses the first partition instead of the
complete ISO file.

Add a check to detect HybridISO files and use offset 0 in addition to
partition table parsing.

Ian Campbell 391419266c libxl: split forced and non-forced uses of libxl__device_del
Most forced users can now simply call libxl__device_destroy directly.

libxl__devices_destroy is something of a special case, it is really
just iterating over an opaque set of xenstore directories and removing
them. Until this can be refactored just do the force-remove case
manually, doing otherwise led to too much entanglement with the other
callers of libxl__device_destroy which do know about specific device
types.

For the time being do the same in libxl__device_pci_remove_xenstore.

Ian Campbell 2720c32fad libxl: separate forced and non-forced device remove.
The function libxl__device_destroy currently takes a force parameter however:

  * in the forced case we initiate a graceful shutdown and then
    immediately nuke the backend directory, quite likely before anyone
    got a chance to react.

  * the callers all have a "wait" variable and pass in "!wait" as the
    force argument which is confusing since not waiting is not really
    the same thing as forcing the destroy.

Therefore split the function into libxl__device_remove and
libxl__device_destroy. The former initiates a graceful shutdown which
the latter simply nukes the backend directory.

This makes some of the callers look a bit odd but that should fall out as I
continue to pull this piece of string.
