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.

Update list of privileged xenoprof operations which were not in sync
with new added functions.
Since the number of privileged operations is larger than the non
privileged ones, change the logic to list unprivileged ones instead.
Also added a few printk statements on failed xenoprof initialization
to identify the source of the problem.

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.
