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
permits 'src/util' now. It _should_ be removed as soon as fixing all.

I've moved all the printing from cmdDomblkinfoPrint() to cmdDomblkinfo(),
and renamed the cmdDomblkinfoPrint() to cmdDomblkinfoGet(), since nature of
that function changed from gathering and printing informations only to
gathering information. This I believe simplifies the functions and
makes the implementation of vshTable API simpler.

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.

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().

When running an armv7l guest on an aarch64 hosts, the
qemu-system-aarch64 binary should be our first choice instead
of qemu-system-arm since the former can take advantage of KVM
acceleration.
Move the special case to virQEMUCapsFindBinaryForArch() so
that it's handled along with all other cases rather than on
its own later on.
Doing so will also make further refactoring easier.

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.

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.

This change actually changes the behaviour of xenConfigGetString() as
now it returns a newly-allocated string.
Unfortunately, there's not much that can be done in order to avoid that
and all the callers have to be changed in order to avoid leaking the
return value.
Also, as a side-effect of the change above, the function now takes a
"char **" argument instead of a "const char **" one.

There seems to be no need to add the ignore_value wrapper or

let's just be consistent - those that care to check the return
