The shadow code uses hvm_get_guest_ctrl_reg(v, 4) to test whether
PAE is enabled or not. But it is not always right if the hypervisor
calls hvm_get_guest_ctrl_reg(v, 4) between vmxassist_invoke and
vmxassist_restore
The patch uses the d->arch.hvm_vmx.cpu_state to test if the PAE is
enabled.
Also update SVM code to use the new 'pae_enabled' hvm func.

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().

This allows the shadow destructor hook in free_page_type()
to work properly.
Also, move mark_dirty() back to alloc/free_page_type(). It
doesn't matter that this happens before the type count is
modified -- bitmap is extracted by the tools with the domain
paused, so these non-blocking paths are atomic from p.o.v of
the tools.

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.
