s390: wire up nmi command to raise a RESTART interrupt on S390
There is the 'nmi' command that is used to trigger a guest dump via kdump feature on x86.
s390 uses RESTART interrupt to trigger kdump.
So, this patch provides a mean to use 'nmi' command on s390 to raise RESTART interrupt.
The CPU to receive the RESTART interrupt is the "default" one.
There is an infrastructure to select the "default" CPU using 'cpu' command.
The 'info cpus' command can be used to see which one is the "default".
In order to wire up the RESTART to 'nmi' command we had to:
1. implement the kvm_s390_cpu_restart function by exporting the existing code
2. implement s390_cpu_restart function as kvm-aware wrapper
3. modify the qmp_inject_nmi function to enable (for s390) the scan for
"default" CPU and call s390_cpu_restart for it;
3. fix some messages.

monitor: support sub command in help
The old code in help_cmd() uses global 'info_cmds' and treats it as a
special case. Actually 'info_cmds' is a sub command group of 'mon_cmds',
in order to avoid direct use of it, help_cmd() needs to change its work
mechanism to support sub command and not treat it as a special case
any more.
To support sub command, help_cmd() will first parse the input and then call
help_cmd_dump(), which works as a reentrant function. When it meets a sub
command, it simply enters the function again. Since help dumping needs to
know whole input to printf full help message include prefix, for example,
"help info block" need to printf prefix "info", so help_cmd_dump() takes all
args from input and extra parameter arg_index to identify the progress.
Another function help_cmd_dump_one() is introduced to printf the prefix
and command's help message.
Now help supports sub command, so later if another sub command group is
added in any depth, help will automatically work for it. Still "help info
block" will show error since command parser reject additional parameter,
which can be improved later. "log" is still treated as a special case.

vmdk: support vmfsSparse files
VMware ESX hosts use a variant of the VMDK3 format, identified by the
vmfsSparse create type ad the VMFSSPARSE extent type.
It has 16 KB grain tables (L2) and a variable-size grain directory (L1).
In addition, the grain size is always 512, but that is not a problem
because it is included in the header.
The format of the extents is documented in the VMDK spec. The format
of the descriptor file is not documented precisely, but it can be
found at http://kb.vmware.com/kb/
10026353 (Recreating a missing virtual
machine disk (VMDK) descriptor file for delta disks).
With these patches, vmfsSparse files only work if opened through the
descriptor file. Data files without descriptor files, as far as I
could understand, are not supported by ESX.
