Pulls in several portability fixes, including the fact that gnulib
now only works on platforms with two's complement signed integers.
Also makes for a smaller delta on the next update (we are waiting
on a license change to unsetenv for the sake of mingw).

* .gnulib: Update to latest.
* bootstrap: Resync from upstream.
* tests/virstringtest.c: Drop use of obsolete probes of integer
properties.

This patch fixes an issue where screenshot API call was failing when
the esx/vcenter password contains special characters such as
apostrophee. The reason for failures was that passwords were escaped
for XML and stored in esxVI_Context which was then passed to raw CURL
API calls where the password must be passed in original form to
authenticate successfully. So this patch addresses this by storing
original passwords in the esxVI_Context struct and escape only for
esxVI_Login call.

Commit ff212622 changed the error message to be more
detailed about the failure at hand; however, while the new
error message claims that "bus must be <= index", the error
message is displayed if "idx <= addr->bus", ie. when bus
is larger than or *equal to* index.

Change the error message to report the correct constraint,
and format it in a way that mirrors the check exactly to
make it clearer to people reading the code. The new error
message reads "index must be larger than bus".

This patch aims to fix observed crash on daemon shutdown. Main thread is in
the process of state drivers cleanup, network driver is cleaned up and
qemu driver is not yet. Meanwhile eof event from qemu process triggers
qemuProcessStop -> networkReleaseActualDevice and crash happens as
network driver is already cleaned up.

This is because there's a known issue where ESX will refuse to attach
drives bigger than 4TB when virtualHW < 9. Therefore, to avoid that
use the higher virtualHW for hosts that support it.

This patch fixes an issue where vMotion fails when VMCI device is not
present in the vmx file.

When a SCSI controller is present, ESX adds several pciBridge devices
to vmx file. This fixes an error message where it refuses to create VM
due to not enough PCI devices available. This applies only to virtualHW
version >= 7.

Hand-entering indexes for 20 PCI controllers is not as tedious as
manually determining and entering their PCI addresses, but it's still
annoying, and the algorithm for determining the proper index is
incredibly simple (in all cases except one) - just pick the lowest
unused index.

The one exception is USB2 controllers because multiple controllers in
the same group have the same index. For these we look to see if 1) the
most recently added USB controller is also a USB2 controller, and 2)
the group *that* controller belongs to doesn't yet have a controller
of the exact model we're just now adding - if both are true, the new
controller gets the same index, but in all other cases we just assign
the lowest unused index.

With this patch in place and combined with the automatic PCI address
assignment, we can define a PCIe switch with several ports like this:

  <controller type='pci' model='pcie-root-port'/>
  <controller type='pci' model='pcie-switch-upstream-port'/>
  <controller type='pci' model='pcie-switch-downstream-port'/>
  <controller type='pci' model='pcie-switch-downstream-port'/>
  <controller type='pci' model='pcie-switch-downstream-port'/>
  <controller type='pci' model='pcie-switch-downstream-port'/>
  <controller type='pci' model='pcie-switch-downstream-port'/>
  ...

These will each get a unique index, and PCI addresses that connect
them together appropriately with no pesky numbers required.

Make virDomainControllerFindUnusedIndex() a global function so that it
can be used outside domain_conf.c (as well as higher up in
domain_conf.c itself)/ Also make its DomainDef arg a const* so that
functions which only have a const* to the domain can use it.

IS_USB2_CONTROLLER() is useful in more places aside from just when
assigning PCI addresses in QEMU, and is checking for enum values that
are all defined in conf/domain_conf.h anyway, so define it there
instead.

Add .domainInterfaceAddresses so that user can have a way to
get domain interface address by 'virsh domifaddr'. Currently
it only supports '--source lease'.

Add support for the slic_table to the security drivers.

<os>
  <acpi>
    <table type="slic">/path/to/acpi/table/file</table>
  </acpi>

will result in:

-acpitable sig=SLIC,file=/path/to/acpi/table/file

This refactor also makes a distinction between the pointer to the
original definition and copied one to prevent mixups.

Use virDomainCputune struct to store the data rather than exploding the
fields and use macros to fill the typed params.

cgroup functions set and get the longer type so use it everywhere

Get rid of lots of duplicated code.

Introduce a macro to assign the parameters to avoid the for loop and
shuffle around various checks for a simpler and saner function.

Use virDomainObjGetDefs since the API guarantees that both live and
config are never set together.

The caller is already aware that the params are missing and the
extractor is ignoring the missing ones so the parameter isn't necessary.

ESX will refuse to attach VMDKS that have buslogic adatper type to 64bit
VMs whereas lsilogic works fine both 32bit and 64bit VMs.

Xen only supports network-based disks with the qemu (aka qdisk) driver.
Set the driverName to 'qemu' in libxlDomainDeviceDefPostParse() if
not already set. When starting a domain with network-based disks,
ensure the driverName is 'qemu'.

Resolves: https://bugzilla.opensuse.org/show_bug.cgi?id=981094

The libvirt internal bits can be changed for disks that don't otherwise
support changing media. Remove the switch statement and allow changes of
non-source data for all disks.

qemuDomainChangeDiskLive rolled back few changes to the disk definition
if changing of the media failed. This can be avoided by moving some code
around.

Commit id '15ccb0db' added job functions for the lxc driver; however,
for shutdown and nonpersistent path, the vm was removed from the domain
object list and the vm pointer cleared before the endjob.

Adjust the code to perform the endjob first and then perform the
ObjListRemove as long as the vm wasn't NULL. This follows more closely
models from qemu and libxl

Based on some digital archaeology performed by jtomko, it's been determined
that the persistentAddrs variable is no longer necessary...

The variable was added by:
commit 141dea6b
CommitDate: 2010-02-12 17:25:52 +0000
    Add persistence of PCI addresses to QEMU

Where it was set to 0 on domain startup if qemu did not support the
QEMUD_CMD_FLAG_DEVICE capability, to clear the addresses at shutdown,
because QEMU might make up different ones next time.

As of commit f5dd58a6
CommitDate: 2012-07-11 11:19:05 +0200
    qemu: Extended qemuDomainAssignAddresses to be callable from
    everywhere.

this was broken, when the persistentAddrs = 0 assignment was moved
inside qemuDomainAssignPCIAddresses and while it pretends to check
for !QEMU_CAPS_DEVICE, its parent qemuDomainAssignAddresses is only
called if QEMU_CAPS_DEVICE is present.

Since commit id '20a0fa8e' removed the QEMU_CAPS_DEVICE, Coverity notes
that it's no longer possible to have 'addrs' be NULL when checking for
a live domain since qemuDomainPCIAddressSetCreate would have jumped to
cleanup if addrs was NULL.

Instead of setting the flag before parsing the PCI address, set
it afterwards. This ensure we can never end up in a situation
where the flag has been set but pci_dev.physical_function has
not been filled in.

Commit c8b1a836 changed the function, making it
impossible for callers to be able to tell whether a
non-negative return value means "physical function
address found and parsed correctly" or "couldn't find
corresponding physical function".

The important difference between the two being that,
in the latter case, the returned pointer is NULL and
should never, ever be dereferenced.

In order to cope with these changes, the callers
have to be updated.

Just an extra precaution in case the function returns early
due to an OOM error.

Use the detected tray presence flag to trigger the tray waiting code
