Currently, guest_linear_to_real to_real() in vmxassist assumes guest HVM
use 2 level page table when entering protect mode with PG enabled. Vista
uses 3 level (PAE enabled) page table, so memory addressing is wrong.
This patch fixes it, by considering all 4 possible cases.

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().

If a value of "--ms_per_sample" option is larger than a value of
"--time" option, xenmon may generate no log file. So, too large
"--ms_per_sample" should be treated as an error.
e.g.
% xenmon.py --ms_per_sample=2000 -t 1 -n
usage: xenmon.py [options]
xenmon.py: error: option --ms_per_sample: too large (> 1000 ms)
# Notice that a unit of "--time" is a second.

libxc is modified. Previously, the xc_domain_dumpcore_via_callback()
did not respond to error when copy_from_domain_page() failed.
In other words, the dump core remained silent even if mapping the domain
memory failed and its page could not be copied. When this happened,
erroneous data had been dumped to the file without the user realizing it.
Now, it has been modified so that if copy_from_domain_page fails,
this fact is recorded in the logfile and make imcoplerte-list.
However even in such cases, the dumping will continue as before.

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.

passed. Future device model support for the vTPM will read parameters
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.

output seems to be broken up into multiple write()s (depending on the
version of busybox?). Unfortunately /dev/tpm0 needs to have the complete
command written to in one chunk. The work-around 'echo <string> > file ;
cat file > /dev/tpm0' seems to get around this problem.
The patch also removes a redundant test and error output.

If an error occurs, such as wget failing because the site (or proxy)
is unavailable, the script will now terminate, rather than trying
to soldier on without any real hope of success.
mkbuildtree should really get the same treatment, but that
can wait for another day.

There is a race condition between domain_create_ring() and the removal
of the domU entry from xenstore. If the removal of the domU entry from xenstore
comes later than the first xs_gather() call in domain_create_ring(), it will go
on and bind the evtchn port to the dying domU, which will cause below error

about. It is tested with xm-test and by manually running the xm
commands. It also handles the return case (reported by Masaki Kanno)
that was missed in the originally patch.
