There are two separate Xen hypervisors (HVM and PVM), as well as two
different Xen commands (xl and xm). This already provides four different
combinations and future changes might bring even more. For this reason
the test classes for the Xen hypervisor are not defined manually, but
rather generated at module load time. Doing so makes it possible to keep
using the standard unit test infrastructure provided by the “unittest”
module.

Using “super”, which we try to avoid in other places, is necessary to
call functions provided by other classes.

The “_GetConfigFileDiskData” function is moved to module level and
cleaned up (module-level constants for letters and file I/O drivers).

Until now only 24 disks would be supported (e.g. “sda” to “sdx”), when
the Latin alphabet actually has 26 characters. Now all 26 letters would
be available for use (“constants.MAX_DISKS” is still 16).

Newly added unit tests provide complete coverage for
“_GetConfigFileDiskData”.

Since modules are not directly executables, remove the shebang from
them. This helps with lintian warnings.

Also make the autogenerated _autoconf.py contain two comment lines at
the beginning, like the other modules.
