d4a8fa0cd1 libxl: set shadow memory for any guest type, not only HVM
Otherwise starting PVH guest will result in "arch_setup_bootlate:
mapping shared_info failed (pfn=..., rc=-1, errno: 12): Internal error".

After this change the behavior is the same as in `xl`.

996f101431 lxc: Resolve memory leak
Commit 40b5c99a modified the virConfGetValue callers to use
virConfGetValueString. However, using the virConfGetValueString
resulted in leaking the returned @value string in each case.
So, let's modify each instance to use the VIR_AUTOFREE(char *)
syntax. In some instances changing the variable name since
@value was used more than once.

This patch introduces a new rule to check misaligned stuff in parenthesis:
1. For misaligned arguments of function
2. For misaligned conditions of [if|while|switch|...]

There're too much misalignment, so it adds a temporary filter which

2f754b26cb qemu: Update hostdevs device lists before connecting qemu monitor
In a following case:

    virsh start $domain
    service libvirtd stop
    <shutdown> the guest from within the $domain
    service libvirtd start

Notice that PCI devices which have been assigned to the $domain will
still be bound to stub drivers instead rebound to host drivers.
In that case the call stack is like below:

    libvirtd start
        qemuProcessReconnect
            qemuProcessStop (because $domain was shutdown without
                             libvirtd event to process that)
                qemuHostdevReAttachDomainDevices
                    qemuHostdevReAttachPCIDevices
                        virHostdevReAttachPCIDevices

However, because qemuHostdevUpdateActiveDomainDevices was called
after the qemuConnectMonitor, the setup of the tracking of each
host device in the $domain on either the activePCIHostdevs list
or inactivePCIHostdev list will not occur in an orderly manner.
Therefore, virHostdevReAttachPCIDevices just neglects these host PCI
devices which are bound to stub drivers and doesn't rebind them to
host drivers.

This patch fixs that by moving qemuHostdevUpdateActiveDomainDevices before
qemuConnectMonitor during libvirtd reconnection processing.

83d86e348e qemu: Stop looking after finding the first binary
When the guest is native, we are currently looking at
potential KVM binaries regardless of whether or not we have
already located a QEMU binary suitable to run the guest.

This made sense back when KVM support was not part of QEMU
proper, but these days the KVM binaries are in most cases
just trivial wrapper scripts around the native QEMU binary
so it doesn't make sense to poke at them unless they're
the only binaries on the system, such as when running on
RHEL.

This will allow us to simplify both virQEMUCapsInitGuest()
and virQEMUCapsInitGuestFromBinary().

b37b41f868 qemu: Don't duplicate binary name in capabilities
virCapabilitiesAddGuestDomain() takes an optional binary
name: this is intended for cases where a certain domain
type can't use the default one registered for the guest
architecture, but has to use a special binary instead.

The current code, however, will pass 'binary' again when
'kvmbin' is not defined, which is unnecessary as 'binary'
has been registered as default earlier, and will result
in capabilities output such as

  <emulator>/usr/bin/qemu-system-x86_64</emulator>
  <domain type='qemu'/>
  <domain type='kvm'>
    <emulator>/usr/bin/qemu-system-x86_64</emulator>
  </domain>

with the second <emulator> element providing no additional
information.

Change it so that, when 'kvmbin' is not defined, NULL is
passed and so the default emulator will be used instead.

5f0c1c1e25 xen_common: Change xenParsePCIList to use virConfGetValueStringList
The `if(!list || list->type != VIR_CONF_LIST)` check couldn't be
written in a 100% similar way. Instead, we're just checking whether
`virConfGetValueStringList() <= 0` and creating a new function to:
- return -1 in case virConfGetValueStringList fails either due to some
  allocation failure or when traversing the list;
- resetting the last error and return 0 otherwise;

Taking this approach we can have the behaviour with the new code as
close as possible to the old one.
