Since the maxvcpus command query the maximum number of virtual
CPUs supported for a guest VM on this connection, it should be
in virsh-host.c but not virsh-domain.c.

Convert the type of loop iterators named 'i', 'j', k',
'ii', 'jj', 'kk', to be 'size_t' instead of 'int' or
'unsigned int', also santizing 'ii', 'jj', 'kk' to use
the normal 'i', 'j', 'k' naming

The source code base needs to be adapted as well. Some files
include virutil.h just for the string related functions (here,
the include is substituted to match the new file), some include
virutil.h without any need (here, the include is removed), and
some require both.

The function is used to establish connection so it should be in the main
virsh file. This movement also enables further improvements done in next
patches.

Note that the "connect" command has moved from the host section of virsh to the
main section. It is now listed by 'virsh help virsh' instead of 'virsh help
host'.

Use the new helpers to determine mutually exclusive options and touch up
some parts to simplify the code.

After we switched to C99 initialization, I noticed there were many
places where the specification of .flags parameter differed.  After
going through many options and deciding whether to unify the
initialization to be '.flags = 0' or '.flags = VSH_OFLAG_NONE', I
realized both can be removed and it makes the code easier to go
through.

Linefeed is missed in the help of node-memory-tune.
This patch just adds '\n' to get a correct help message.

The QEMU specific APIs all operate on domains, not the host,

The virNodeSuspend API allows for a duration of 0, to mean no
timed wakup. virsh needlessly forbids this though
Signed-off-by: NDaniel P. Berrange <berrange@redhat.com>

The 3 options accept 0, and merely checking for non-zero values
would cause wrong results.

The libvirt coding standard is to use 'function(...args...)'
instead of 'function (...args...)'. A non-trivial number of
places did not follow this rule and are fixed in this patch.

We always expose individual bits from flags as separate options rather
than exposing a raw flags options. Since virNodeSuspendForDuration does
not currently support any flags, the only way of using this --flags
options that would not fail is "--flags 0", which is equivalent to
omitting the option. Thus it is highly unlikely anyone would actually be
using it and removing it should be safe.

- Added a new host command nodecpumap
- Added documentation

Upstream kernel introduced new sysfs knob "merge_across_nodes" to
specify if pages from different numa nodes can be merged. When set
to 0, only pages which physically reside in the memory area of
same NUMA node can be merged. When set to 1, pages from all nodes
can be merged.

This patch supports the tuning by adding new param field
"shm_merge_across_nodes".

I was using qemu-monitor-command during development, and found it quite
hard to use.  Compare the results of this patch on ease of reading:

$ virsh qemu-monitor-command          dom '{"execute":"query-version"}'
{"return":{"qemu":{"micro":1,"minor":12,"major":0},"package":"(qemu-kvm-0.12.1.2)"},"id":"libvirt-7683"}

$ virsh qemu-monitor-command --pretty dom '{"execute":"query-version"}'
{
    "return": {
        "qemu": {
            "micro": 1,
            "minor": 12,
            "major": 0
        },
        "package": "(qemu-kvm-0.12.1.2)"
    },
    "id": "libvirt-7674"
}

* tools/virsh-host.c (cmdQemuMonitorCommand): New option.
* tools/virsh.pod (qemu-monitor-command): Document it.

https://www.gnu.org/licenses/gpl-howto.html recommends that
the 'If not, see <url>.' phrase be a separate sentence.

* tests/securityselinuxhelper.c: Remove doubled line.
* tests/securityselinuxtest.c: Likewise.
* globally: s/;  If/.  If/

New command node-memory-tune to get/set the node memory parameters,
only two parameters are allowed to set (pages_to_scan, and sleep_millisecs,
see documents in this patch for more details).

Example of node-memory-tune's output:

Shared memory:
	pages_to_scan   100
	sleep_millisecs 20
	pages_shared    0
	pages_sharing   0
	pages_unshared  0
	pages_volatile  0
	full_scans      0

Now that vshCommandRun() checks for the connection automaticaly, remove
all of the redundant checks in the code.

vshConnectionUsability() no longer needs to be exported and this patch
marks it static.

Although virsh command raises a correct error information, the command status
returns 0(true), this patch is used for fixing this issue.

In preparation for splitting virsh-interface.c, I found these
functions need to be declared in virsh.h, as well as one that
belongs more properly in virsh-domain.h.  Also, since we
use the VSH_BY* flags in more than one function, I improved
how they are used.

* tools/virsh.h (vshNameSorter, vshCmdHasOption): Declare.
(VSH_BYID): Turn into enum.
(vshCommandOptDomainBy): Move...
* tools/virsh-domain.h): ...here.
* tools/virsh.c: (vshNameSorter): Export.
(cmd_has_option): Rename...
(vshCmdHasOption): ...and export.
(vshCommandOptDomainBy): Move...
* tools/virsh-domain.c (vshCommandOptDomainBy): ...here, adjust
signature, and check flags.
* tools/virsh-network.c (vshCommandOptNetworkBy): Update callers.
* tools/virsh-nwfilter.c (vshCommandOptNWFilterBy): Likewise.
* tools/virsh-secret.c (vshCommandOptSecret): Likewise.
* tools/virsh-domain-monitor.c (includes): Likewise.
* tools/virsh-host.c (includes): Likewise.

The splits are getting easier, with fewer cleanups needed in virsh.h.

* tools/virsh-host.h: New file.
* tools/Makefile.am (virsh_SOURCES): Build it.
* tools/virsh-host.c: Use new header.
* tools/virsh.c: Likewise.

List:
 - some old libvir/libvirt rename leftovers (the only problem can be
   if somebody parses 'virsh version' output really badly)
 - remove pointless tags specified in some pages that are not used

Change the permissible minimum value of nodesuspend duration time
to 60 seconds. If option is less than the value, reports error.
Update virsh help and manpage the infomation.

* virsh-domain-monitor.c: Add domMonitoringCmds
* virsh-domain.c: Add domManagementCmds
* virsh-host.c: Add hostAndHypervisorCmds
* virsh-interface.c: Add ifaceCmds
* virsh-network.c: Add networkCmds

* virsh-volume.c: Add storageVolCmds
* virsh.c: Remove all the above *Cmds.

Commands in host group moved from virsh.c to virsh-host.c,

* virsh.c: Remove commands in host group.
* virsh-host.c: New file, filled with commands in host group
* po/POTFILES.in: Add virsh-host.c
* cfg.mk: Skip to check config.h including for virsh-host.c
