Export the disk index in the import/export scripts
We want to export the disk index as some OSes will only want to export
the first disk (or the second one, etc.), even if we have multiple
disks.
The patch also updates the backend.ExportSnapshot docstring.

http library: Always fork before reading request
It turned out that clients not sending a full request will stop
us from responding to further requests. This patch leverages the
situation a bit by always forking before handling the request,
but we still have DoS situations.

LUCreateInstance: import multiple disks
Previously we used to handle only one disk. Now we'll import all the
ones present in the export, in order, on the instance's disks. Any disk
which was present on the original instance but wasn't exported is just
skipped in the target instance.

Convert ImportOSIntoInstance to OS API 10
- Change ImportOSIntoInstance not to get any "os_disk" and "swap_disk"
arguments but to accept multiple target images to import, and to
return a list of booleans with the result of each import
- Change the relevant rpc call and the only caller to conform
- Pass arguments to the import script through the environment
- Run one import os script for each disk image, passing an IMPORT_DEVICE

Convert ExportSnapshot to OS API 10
We pass the data via the environment rather than on the command line, as

as the master calls this function for every snapshotted disk.

LUExportInstance: snapshot all disks
Rather than just snapshotting the "sda" disk, we'll snapshot all of the
instance disks. If we can't snapshot a disk for any reason we'll log an
error and proceed anyway: in this case the resulting export will miss a
disk. This also changes all the warning messages to self.LogWarning().

Improve the mcpu.Processor logging routines
As discussed previously, many of the routinges in cmdlib.py are using
logging functions as a carry-over from 1.2 (when these also showed the
message on stderr/to the user), instead of actually warning the user.
This patch extends the syntax for Processor.LogInfo/LogWarning in order
to be easier to use them.

Generalize the reading of test file data
Currently we have two methods in ganeti.bdev_unittest.py of computing
the test data file name - and, of course, they don't give the same
results.
The patch moves the functions to compute the test file name and reading
of its contents to the GanetiTestCase class in testutils, which allows
running the tests from the command line as well.
We also change assertFileContent to use utils.ReadFile.
