Removing try,except block as cfgbootpolicy should allow exceptions to
propagate instead of printing traceback to stdout.

Introducing an OptionError exception to be used by all xm subcommands
to signal an error in the arguments. "xm" will catch these and output
the appropriate error and usage message.
Detailed Changes:
main.py:
* Cleaned up imports and moved warning filter outside of
import block.
* Converted usage parameters and description to a python
dict rather than strings to enable better usage help
formatting.
* Removed unused list_label domain command.
* Added cmdHelp() prints out usage message for any command
* Added shortHelp() prints out the default help message when
xm is invoked with no arguments.
* Added longHelp() prints out long help message when invoked
with xm --help or xm help.
* Added extra optional paramter to getDomains() so we can
tell Xend not to poll devices. This will speed up xm list.
(PENDING changes to Xend itself.)
* Changed all references where 'dom' actually means 'domid'
to use the correct name.
* Changed 'xm list' header format to use printf formatting style.
* Renamed xm_subcommand to xm_importcommand so it is more
clear what it is doing (all xm commands are subcommands!)
* Moved cpu_make_map() inside xm_vcpu_pin as an anonymous func.
* Use OptionError whenever an invalid option is detected in xm.
* Added proper catch and error printing for XendError and
OptionErrors in main().

xm dump-core [-L|--live][-C| --crash] <domID> [output path]
-L| --live Live dump:
By default, xm dump does an xm pause, unpause before and
after taking the dump, respectively. This option disables
the pause/unpause and simply takes the dump.
-C :| --crash crash dump:
This executes an xm destroy after the dump file is complete.
The output path is optional, and if it is not specified, the path will be
/var/xen/dump/<domU name>.<domU ID>.core
This command uses the existant dumpCore(), which has been used for
coredump when a domU crashed.

from the xenstore and won't need the command line parameter(s).
The patch includes a small change to the debugging output for the vTPM
module.

about. It is tested with xm-test and by manually running the xm

that was missed in the originally patch.

call to determine the initial reservation separately from the amount of
memory to be freed up by ballooning -- when using QEMU, we lose 8 MiB to video
RAM, which must be accounted for when ballooning, but _not_ accounted for

Driver changes: Make backend drivers check it when entering Closed
state, only unregister devices when the "online" node is either "0" or
not present. The later maintains backward compatibility.
Tools changes: Update "online" node when creating and hot-unplugging
devices.
Background: When kexec'ing a new kernel, the old kernel's frontend
driver will shutdown, but the backend device should *NOT* disappear
due to that, so the new kernel instance can reconnect.
