Compilation on mingw was warning about %lld use in fprintf, and
in the gnulib strptime module about dead labels.

* tools/virsh.c (vshPrint): Change redirect.
(vshPrintExtra): Allow use within vshPrint.  Avoid fprintf on
arbitrary formats, since we aren't using gnulib module; instead,
use virVasprintf to pre-format.
(vshError): Likewise.
* .gnulib: Update to latest, for mingw strptime warning fix.
Reported by Matthias Bolte.

Win32 doesn't have a concept of signal masks so disable that
code. It is unclear how SIGINT is delivered (if at all) on
Win32, so this might further work to provide an alternative
to pthread_sigmask

* tools/virsh.c: Avoid pthread_sigmask on Win32

* tools/virsh.c (cmdSysinfo): New function.
(hostAndHypervisorCmds): Add it.
* tools/virsh.pod: Document it.

Currently users who want to use virDomainQemuMonitorCommand() API or
it's virsh equivalent has to use the same protocol as libvirt uses for
communication to qemu. Since the protocol is QMP with current qemu and
HMP much more usable for humans, one ends up typing something like the
following:

    virsh qemu-monitor-command DOM \
'{"execute":"human-monitor-command","arguments":{"command-line":"info kvm"}}'

which is not a very convenient way of debugging qemu.

This patch introduces --hmp option to qemu-monitor-command, which says
that the provided command is in HMP. If libvirt uses QMP to talk with
qemu, the command will automatically be converted into QMP. So the
example above is simplified to just

    virsh qemu-monitor-command --hmp DOM "info kvm"

Also the result is converted from

    {"return":"kvm support: enabled\r\n"}

to just plain HMP:

    kvm support: enabled

If libvirt talks to qemu in HMP, --hmp flag is obviously a noop.

* tools/virsh.pod

* src/fdstream.c (virFDStreamOpenFile, virFDStreamCreateFile):
Use VIR_FORCE_CLOSE instead of close.
* tests/commandtest.c (mymain): Likewise.
* tools/virsh.c (editFile): Use virCommand instead of system.
* src/util/util.c (__virExec): Special case preservation of std
file descriptors to child.

Use it in all places where a memory or storage request size is converted
to a larger granularity. This avoids requesting too small memory or storage
sizes that could result from the truncation done by a simple division.

This extends the round up fix in 6002e040
to the whole codebase.

Instead of reporting errors for odd values in the VMX code round them up.

Update the QEMU Argv tests accordingly as the original memory size 219200
isn't a even multiple of 1024 and is rounded up to 215 megabyte now. Change
it to 219100 and 219136. Use two different values intentionally to make
sure that rounding up works.

Update virsh.pod accordingly, as rounding down and rejecting are replaced
by rounding up.

This will iterate over all NUMA nodes, showing
free memory for each and sum at the end.
Existing default behavior is not changed.

If the memory of guest OS is changed constantly, the live migration
can not be ended ever for ever.

We can use the command 'virsh migrate-setmaxdowntime' to control the
live migration. But the value of maxdowntime is diffcult to calculate
because it depends on the transfer speed of network and constantly
changing memroy size. We need a easy way to control the live migration.

This patch adds the support of forcing guest to suspend at timeout.
With this patch, when we migrate the guest OS, we can specify a
timeout. If the live migration timeouts, auto-suspend the guest OS,
where the migration will complete offline.

Show migration progress if `migrate --verbose'.

While migration is in progress and virsh is waiting for its
completion, user may want to terminate the progress by pressing
Ctrl-C. But virsh just exits on user's Ctrl-C leaving migration
in background that user isn't even aware of. It's not reasonable.

This patch changes the behaviour for migration. For other
commands Ctrl-C still terminates virsh itself.

bugfix for https://bugzilla.redhat.com/show_bug.cgi?id=671050

virsh simply refutes to detach-interface in case when multiple
interfaces are attached and --mac is not specified.

* .gnulib: Update to latest, for sigpipe and sigaction modules.
* bootstrap.conf (gnulib_modules): Add siaction, sigpipe, strerror_r.
* tools/virsh.c (vshSetupSignals) [!SIGPIPE]: Delete, now that
gnulib guarantees it.
(SA_SIGINFO): Define for mingw fallback.
* src/util/virterror.c (virStrerror): Simplify, now that gnulib
guarantees the POSIX interface.
* configure.ac (AC_CHECK_FUNCS_ONCE): Drop redundant check.
(AM_PROG_CC_STDC): Move earlier, to keep autoconf happy.

* tools/libvirt-guests.init.in: Rename...
* tools/libvirt-guests.init.sh: ...so that xgettext's language
detection via suffix will work.
* po/POTFILES.in: Update all references.
* tools/Makefile.am (EXTRA_DIST, libvirt-guests.init): Likewise.

* tools/libvirt-guests.init.sh: Use only POSIX shell features, which
includes using gettext.sh for translation rather than $"".
* tools/Makefile.am (libvirt-guests.init): Supply a few more substitutions.
* po/POTFILES.in: Mark that libvirt-guests.init needs translation.

* tools/virsh.c (cmdRunConsole, cmdConsole): Rename problematic

Reported by Justin Clift.

Remove the optional option "group", as cmdHelp should accepts
only one option ("virsh help" supports both command and command
group now, and user rarely uses the options, so it doesn't matter
much for it being longer, :-)

* tools/virsh.c

Now includes information on keyword usage, and provides examples.

* tools/virsh.c (find-storage-pool-sources-as and find-storage-pool-sources
should't be in command group "Domain Management", move them to group
"Storage Pool".

* tools/virsh.c (virsh shouldn't use 'phy' as the disk driver if
user doesn't specify "--driver", it causes bugs, as not all of
hypervisor driver supports 'phy', and actually hypervisor should
known the correct default disk driver and subdriver, so remove it)

As virsh help supports both command and command group now,
update "cmdHelp" to print consite help, (this patch is
increment of "78290527").

And also remove redundant empty line in "vshUsage".

* tools/virsh.c

The output was previously:

    -c | --connect <uri>    hypervisor connection URI
    -r | --readonly         connect readonly
    -d | --debug <num>      debug level [0-5]

    -t | --timing           print timing information
    -l | --log <file>       output logging to file
    -v | --version[=short]  program version

    -V | --version=long     version and full options

(note the blank line between the --version types)

This patch removes the extra blank line.

Change the virsh help out. The new output of "virsh help" and
"virsh --help" will be like:

 Secret (help keyword 'secret'):
    secret-define                  define or modify a secret from an XML file
    secret-dumpxml                 secret attributes in XML
    secret-set-value               set a secret value
    secret-get-value               Output a secret value
    secret-undefine                undefine a secret
    secret-list                    list secrets

 Snapshot (help keyword 'snapshot'):
    snapshot-create                Create a snapshot
    snapshot-current               Get the current snapshot
    snapshot-delete                Delete a domain snapshot
    snapshot-dumpxml               Dump XML for a domain snapshot
    snapshot-list                  List snapshots for a domain
    snapshot-revert                Revert a domain to a snapshot

Also support output help information of specified command group, e.g.

% ./tools/virsh help "Network Filter"
 Network Filter (help keyword 'filter'):
    nwfilter-define                define or update a network filter from an XML file
    nwfilter-undefine              undefine a network filter
    nwfilter-dumpxml               network filter information in XML
    nwfilter-list                  list network filters
    nwfilter-edit                  edit XML configuration for a network filter

Each group has a help keyword, e.g.

% ./tools/virsh help filter
 Network Filter (help keyword 'filter'):
    nwfilter-define                define or update a network filter from an XML file
    nwfilter-undefine              undefine a network filter
    nwfilter-dumpxml               network filter information in XML

    nwfilter-edit                  edit XML configuration for a network filter
