This is a not-so-nice change, adding support for partitions to be used
as PVs.

The not-nice part is that partitions live in a separate place in
sysfs, whereas in dev they live at the same level as disks. We
workaround this via a new SysfsName function that computes the correct
sysfs base path for a given disk.

The other rule is that if a disk is not in use, we ignore its
partitions completely, as the disk will be re-partitioned anyway. Only
if the disk is busy, we consider each of its partitions for the
free/busy list.

This patch changes lvmstrap to ignore “small” partitions. Currently
extended partitions are reported as unused as with a size of 1024
(bytes), and this confuses lvmstrap. Since a very small partition
won't help anyway (below hundred of PE size is not helpful), let's
restrict it to 1GB.

Similar to mounted filesystems, recent kernel/userland report swap
backends:

    root@node4:~# fuser -avm /dev/sda6
                         USER        PID ACCESS COMMAND
    /dev/sda6:           root     kernel swap  /dev/sda6

But old ones not:

    node1# fuser -avm /dev/sda6
                         USER        PID ACCESS COMMAND
    /dev/sda6:

So we add an explicit test for swap backends using /proc/swaps.

Recent kernels/userland report a mounted filesystem as follows:

    root@node4:~# fuser -avm /dev/sda5
                         USER        PID ACCESS COMMAND
    /dev/sda5:           root     kernel mount /srv/ganeti

But old ones do not:

    node1# fuser -avm /dev/sda5
                         USER        PID ACCESS COMMAND
    /dev/sda5:

So in order to cover both, we add an explicit test for this. We
already compute the device numbers of all mounted filesystems, so it
is a trivial addition (GetMountInfo() is cheap, so we don't need to
cache it).

If a device has entries in its holder directory
(/sys/block/$name/holders), it means that some kernel system "uses"
that device, and hence should not be considered available.

This patch adds a new 'in-use' check based on this sysfs test, and
introduces an overal InUse function for devices.

This patch, originally written by Marc Schmitt <mschmitt@google.com>,
adds support for MD devices (used in a non-partitioned mode). I
abstracted all the original startswith('md') checks into separate
functions, and also moved the supported disk types to a list.

Proper "in-use" detection also needs another check, which will come in
a subsequent patch.

Known issues:

- Code duplication from Ganeti library (e.g. PingByTcp/netutils.TcpPing,
  GetHosts/utils.ReadFile)
- Using ssh-agent doesn't work with more than one worker (Paramiko keeps
  the socket open and the file descriptor is used from different
