Almost done with the splits.

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

One of the simpler splits.

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

Another worthwhile split, needed one more public function.

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

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.

* cfg.mk: Whitelist virsh.h instead of virsh.c for strcasecmp check
* tools/virsh-domain.h, tools/virsh.h: Fix #define indentation

The virsh-domain.c file was pretty self-contained; the only
entry point was the table of command definitions.  The bulk
of this patch is making more functions in virsh.c reusable.
A later patch will clean up poor naming choices.

* tools/Makefile.am (virsh_SOURCES): Build virsh-domain.c.
* tools/virsh-domain.h: New file.
* tools/virsh.h (virshReportError, vshResetLibvirtError)
(vshAskReedit, vshStreamSink): Declare.
* tools/virsh.c: Switch from using .c to .h.
(virshReportError, vshResetLibvirtError, vshAskReedit)
(vshStreamSink, prettyCapacity): Export.
(vshCatchInt): Move...
* tools/virsh-domain.c: ...into sole user.  Use header.

There are a few issues with the current virAtomic APIs

 - They require use of a virAtomicInt struct instead of a plain
   int type
 - Several of the methods do not implement memory barriers
 - The methods do not implement compiler re-ordering barriers
 - There is no Win32 native impl

The GLib library has a nice LGPLv2+ licensed impl of atomic
ops that works with GCC, Win32, or pthreads.h that addresses
all these problems. The main downside to their code is that
the pthreads impl uses a single global mutex, instead of
a per-variable mutex. Given that it does have a Win32 impl
though, we don't expect anyone to seriously use the pthread.h
impl, so this downside is not significant.

* .gitignore: Ignore test case
* configure.ac: Check for which atomic ops impl to use
* src/Makefile.am: Add viratomic.c
* src/nwfilter/nwfilter_dhcpsnoop.c: Switch to new atomic
  ops APIs and plain int datatype
* src/util/viratomic.h: inline impls of all atomic ops
  for GCC, Win32 and pthreads
* src/util/viratomic.c: Global pthreads mutex for atomic
  ops
* tests/viratomictest.c: Test validate to validate safety
  of atomic ops.

Except a bunch of files for security driver, all others are changed
automatically, the copyright for securify files are not complete,
that's why to do it manually:

  src/security/security_selinux.h
  src/security/security_driver.h
  src/security/security_selinux.c
  src/security/security_apparmor.h
  src/security/security_apparmor.c
  src/security/security_driver.c

DBus connection. The HAL device code further requires that
the DBus connection is integrated with the event loop and
provides such glue logic itself.

The forthcoming FirewallD integration also requires a
dbus connection with event loop integration. Thus we need
to pull the current event loop glue out of the HAL driver.

Thus we create src/util/virdbus.{c,h} files. This contains
just one method virDBusGetSystemBus() which obtains a handle
to the single shared system bus instance, with event glue
automagically setup.

To assist people in verifying that their host is operating in an
optimal manner, provide a 'virt-host-validate' command. For each
type of hypervisor, it will check any pre-requisites, or other
good recommendations and report what's working & what is not.

eg

  # virt-host-validate
  QEMU: Checking for device /dev/kvm                                         : FAIL (Check that the 'kvm-intel' or 'kvm-amd' modules are loaded & the BIOS has enabled virtualization)
  QEMU: Checking for device /dev/vhost                                       : WARN (Load the 'vhost_net' module to improve performance of virtio networking)
  QEMU: Checking for device /dev/net/tun                                     : PASS
   LXC: Checking for Linux >= 2.6.26                                         : PASS

This warns people if they have vmx/svm, but don't have /dev/kvm. It
also warns about missing /dev/vhost net.

Don't require dlopen, but link to ole32 and oleaut32 on Windows.

Don't expose g_pVBoxFuncs anymore. It was only used to get the
version of the API. Make VBoxCGlueInit return the version instead.
This simplifies the implementation of the MSCOM glue layer.

Get the VirtualBox version from the registry.

Add a dummy implementation of the nsIEventQueue to the MSCOM glue
as there seems to be no direct equivalent with MSCOM. It might be
implemented using the normal window message loop. This requires
additional investigation.

Replace 'method' with 'function' and get the filename's suffix right.

* global: patch created by running:
for f in $(git ls-files '*.[ch]') ; do
    cppi $f > $f.t && mv $f.t $f
done

This stops libvirt from probing for a libvirtd on the ESX server and
sets the base for the implementation of the secondary drivers.
