The test driver can share the same code with qemu driver when implement
testDomainGetIOThreadsConfig, so extract it for test driver to use.
Also add a new parameter `bitmap_size` to the function, it's used for
specifying the bitmap size of the bitmap to generate, it would be helpful
for test driver or some special situation.

name of an existing device as its parent. We were not previously

When constructing guest name for machined we have to be very
cautious as machined expects a name that's basically a valid URI.
Therefore, if there's a dot it has to be followed by a letter or
a number. And if there's a sequence of two or more dashes they
should be joined into a single dash. These rules are implemented
in virDomainMachineNameAppendValid(). There's the @skip variable
which is supposed to track whether it is safe to append a dot or
a dash into name. However, the variable is set to false (meaning
it is safe to append a dot or a dash) even if the current
character we are processing is not in the set of allowed
characters (and thus skipped over).

Historically, we declared pointer type to our types:
typedef struct _virXXX virXXX;
typedef virXXX *virXXXPtr;
But usefulness of such declaration is questionable, at best.
Unfortunately, we can't drop every such declaration - we have to
carry some over, because they are part of public API (e.g.
virDomainPtr). But for internal types - we can do drop them and
use what every other C project uses 'virXXX *'.
This change was generated by a very ugly shell script that
generated sed script which was then called over each file in the
repository. For the shell script refer to the cover letter:

In short, virXXXPtr type is going away. With big bang. And to
help us rewrite the code with a sed script, it's better if each
variable is declared on its own line.

libxlNodeDeviceDetachFlags() and qemuNodeDeviceDetachFlags() are mostly
equal, aside from how the virHostdevmanager pointer is retrieved and
the PCI stub driver used.
Now that the PCI stub driver verification is done early in both functions,
we can use the virDomainDriverNodeDeviceDetachFlags() helper to reduce
code duplication between them. 'driverName' is checked inside the helper
to set the appropriate stub driver.
The helper is named with the 'Flags' suffix, even when the helper itself
isn't receiving the flags from the callers, to be compliant with the
ACL function virNodeDeviceDetachFlagsEnsureACL() that is being called
inside it and was called from the original functions. Renaming the helper
would implicate in renaming REMOTE_PROC_NODE_DEVICE_DETACH_FLAGS, and all the
related structs inside remote_protocol.x, to be compliant with the ACL
rules.
This is not being checked at this moment, but we'll fix check-aclrules.py to
verify all the helpers that calls ACL functions in domain_driver.c shortly.

The virDomainGenerateMachineName() function doesn't belong in
src/conf/ really, because it has nothing to do with domain XML
parsing. It landed there because of lack of better place in the
past. But now that we have src/hypervisor/ the function should
live there. At the same time, the function name is changed to
match new location.

lxcDomainMergeBlkioDevice() and qemuDomainMergeBlkioDevice()
are the same functions. This duplicated code can't be put in
the existing domain_cgroup.c since it's not cgroup related.
This patch introduces a new src/hypervisor/domain_driver.c to
host this more generic code that can be shared between virt
drivers. This new file is then used to create a new helper
called virDomainDeivceMergeBlkioDevice() to eliminate the code
repetition mentioned above. Callers in LXC and QEMU files
were updated.
This change is a preliminary step for more code reduction of
cgroup related code inside lxcDomainSetBlkioParameters() and
qemuDomainSetBlkioParameters().
