nodedev: fix vport detection for FC HBA

Use the host number as the host number when constructing the sysfs path
instead of the variable we are trying to fill.

libxl: Report connect type as Xen

Currently, the libxl driver reports a connection type of "xenlight".
To be compatible with the legacy Xen driver, it should return "Xen".

Note: I noticed this while testing the libxl driver on OpenStack.
After switching my Xen compute nodes to use the libxl stack, I
could no longer launch instances on those nodes since
hypervisor_type was reported as "xenlight" instead of "xen".
libxl: set bootloader for PV domains if not specified

The legacy xen toolstack will set pygrub as the bootloader if not
specified.  For compatibility, do the same in the libxl driver
iff not using direct kernel boot.
configure: Remove unused brctl check

brctl isn't used anywhere AFAICT
qemu: allow restore with non-migratable XML input

Convert input XML to migratable before using it in
qemuDomainSaveImageOpen.

XML in the save image is migratable, i.e. doesn't contain implicit
controllers. If these controllers were in a non-default order in the
input XML, the ABI check would fail. Removing and re-adding these
controllers fixes it.

libxl: allow only 'ethernet' and 'bridge' interfaces, allow script there

Actually only those interface types are handled correctly so reject
others instead of ignoring settings (i.e. treating as bridge/ethernet
anyway).
Also allow <script/> in 'ethernet' (which should be the only
script-allowing type). Keep <script/> allowed in bridge to be compatible
with legacy 'xen' driver.

Implement dispose method for libxlDomainObjPrivate

When creating a timer/event handler reference counting is used. So it could
be possible (in theory) that libxlDomainObjPrivateFree is called with
reference counting >1. The problem is that libxlDomainObjPrivateFree leave
the object in an invalid state with ctx freed (but still having dandling
pointer). This can lead timer/event handler to core.

This patch implements a dispose method for libxlDomainObjPrivate, and moves
freeing the libxl ctx to the dispose method, ensuring the ctx is valid while
the object's reference count is > 0.

remote: Forbid default "/session" connections when using ssh transport

Without the socket path explicitly specified, the remote driver tried to
connect to the "/system" instance socket even if "/session" was
specified in the uri. With this patch this configuration now produces an
error.

It is still possible to initiate a session connection with specifying
the path to the socket manually and also manually starting the session
daemon. This was also possible prior to this patch,

This is a minimal fix. We may decide to support remote session
connections using ssh but this will require changes to the remote driver
code so this fix shouldn't cause regressions in the case we decide to do
that.
remote: Fix client crash when URI path is empty when using ssh

The parsed path in the URI may be NULL resulting into:

  $ virsh -c qemu+ssh:// list
  Segmentation fault (core dumped)

LXC: s/chroot/chdir in lxcContainerPivotRoot()

...fixes a trivial copy&paste error.

udev: fix crash in libudev logging

Call virLogVMessage instead of virLogMessage, since libudev
called us with a va_list object, not a list of arguments.

Honor message priority and strip the trailing newline.

portability: use net/if.h instead of linux/if.h
Make virNetDevSetupControl() public.

This method is useful not only in virnetdev.c.
BSD: implement virNetDevTapCreate() and virNetDevTapDelete()

Implementation uses SIOCIFCREATE2 and SIOCIFDESTROY ioctls.
Move virGetUserEnt() to where its needed

In the first if case, virGetUserEnt() isn't necessary so don't bother
calling it before determining we need it.
nodedev: Expose sysfs path of device

The name format is constructed by libvirt, it's not that clear to
get what the device's sysfs path should be. This exposes the device's
sysfs path by a new tag <path>.

Since the sysfspath is filled during enumerating the devices by
either udev or HAL. It's an output-only tag.
nodedev_udev: Refactor udevGetDeviceType

Checking if the "devtype" is NULL along with each "if" statements
is bad. It wastes the performance, and also not good for reading.
And also when the "devtype" is NULL, the logic is also not clear.

This reorgnizes the logic of with "if...else" and a bunch of "else if".

Other changes:
   * Change the function style.
   * Remove the useless debug statement.
   * Get rid of the goto
   * New helper udevDeviceHasProperty to simplify the logic for checking
     if a property is existing for the device.
   * Add comment to clarify "PCI devices don't set the DEVTYPE property"
   * s/sysfs path/sysfs name/, as udev_device_get_sysname returns the
     name instead of the full path. E.g. "sg0"
   * Refactor the comment for setting VIR_NODE_DEV_CAP_NET cap type
     a bit.
