We don't need a "default" ktype for a kset.  We should set this
explicitly every time for each kset.  This change is needed so that we
can make ksets dynamic, and cleans up one of the odd, undocumented
assumption that the kset/kobject/ktype model has.

This patch is based on a lot of help from Kay Sievers.

Also add a kobject_init_and_add function which bundles up what a lot of
the current callers want to do all at once, and it properly handles the
memory usages, unlike kobject_register();

This is what the kobject_add function is going to become.

Add this to the kernel and then we can convert the tree over to use it.

Kay pointed out that kobject_set_name was being very stupid, doing two
allocations for every call, when it should just be using the kernel
function kvasprintf() instead.

This change adds the internal kobject_set_name_vargs() function, which
other follow-on patches will be using.

The IBM icom serial driver is using a kobject only for reference
counting, nothing else.  So switch it to use a kref instead, which is
all that is needed, and is much smaller.

Instead of walking from the source down to the root of sysfs, and back
to the target, we stop at the first directory the source and the target
share.

This link:
  /devices/pci0000:00/0000:00:1d.7/usb1/1-0:1.0/ep_81

pointed to:
  ../../../../../devices/pci0000:00/0000:00:1d.0/usb2/2-0:1.0/usb_endpoint/usbdev2.1_ep81

now it just points to:
  usb_endpoint/usbdev1.1_ep81

It isn't that hard to add simple kset attributes, so don't go through
all the gyrations of creating your own object type and show and store
functions.  Just use the functions that are already present.  This makes
things much simpler.

Note, the version_str string violates the "one value per file" rule for
sysfs.  I suggest changing this now (individual files per type supported
is one suggested way.)

This patch reorganizes the way suspend and resume notifications are
sent to drivers.  The major changes are that now the PM core acquires
every device semaphore before calling the methods, and calls to
device_add() during suspends will fail, while calls to device_del()
during suspends will block.

It also provides a way to safely remove a suspended device with the
help of the PM core, by using the device_pm_schedule_removal() callback
introduced specifically for this purpose, and updates two drivers (msr
and cpuid) that need to use it.
