Remove the virsystemdmock.la library and instead make use
of the shared virmockdbus.la library
Signed-off-by: NDaniel P. Berrange <berrange@redhat.com>

A number of test suites want to mock the DBus APIs. To avoid
re-inventing the wheel create a re-usable virmockdbus.la
library for LD_PRELOAD usage.
Signed-off-by: NDaniel P. Berrange <berrange@redhat.com>

Introduce virmock.h which provides some macros to assist in
creation of LD_PRELOAD overrides. When these are used, the
LD_PRELOAD code simply has some stubs which forward to a
wrapper function inside the main test case. This means that
logic for the test no longer has to be split between the
virXXXtest.c and virXXXmock.c files. It will also make it
possible to provide some common reusable modules for mocking
code like DBus.

the hash table used to look for loops in the backing chain.

Other drivers in libvirt (e.g. network, qemu) will automatically
return the "inactive" (persistent configuration) XML of an object when
that object is inactive. The netcf backend of the interface driver
would always try to return the live status XML of the interface, even
when it was down. Although netcf does return valid XML in that case,
for bond interfaces it is missing almost all of its content, including
the <bond> subelement itself, leading to this error message from
"virsh iface-dumpxml" of a bond interface that is inactive:

  error: XML error: bond interface misses the bond element

(this is because libvirt's validation of the XML returned by netcf
always requires a <bond> element be present).

This patch modifies the interface driver netcf backend to check if the
interface is inactive, and in that case always return the inactive XML
(which will always have a <bond> element, thus eliminating the error
message, as well as making operation more in line with other drivers.

This fixes the following bug:

The configure definition previously always defined the GLUSTER_CLI macro
and thus the code needing it wasn't compiled out if the tool wasn't
accessible.

At least Debian uses dash to run the init scripts

Up until now the traffic control filters for the vNIC QoS were
matching only ip traffic. For egress traffic that was unnoticed
because the unmatched traffic would just go to the default htb class
and be shaped anyway. For ingress, though, since the policing of the
rate is done by the filter itself.

The problem is solved by changing protocol to all and making anything
match the filter.

nmdm is a FreeBSD driver which allows to create a pair of tty
devices one of which is passed to the guest and second is used
by the client.

This patch adds new 'nmdm' character device type. Its definition
looks this way:

<serial type='nmdm'>
  <source master='/dev/nmdm0A' slave='/dev/nmdm0B'/>
</serial>

Master is passed to the hypervisior and slave is used for client
connection.

Also implement domainOpenConsole() for bhyve driver based on that.

Right now, virStorageFileMetadata tracks bool backingStoreIsFile
for whether the backing string specified in metadata can be
resolved as a file (covering both block and regular file
resources) or is treated as a network protocol.  But when
merging this struct with virStorageSource, it will be easier
to just actually track which type of resource it is, as well
as have a reserved value for the case where the resource type
is unknown (or had an error during probing).

I'm about to add fields to virStorageFileMetadata, which means
also adding fields to the testFileData struct in virstoragetest.
Alas, adding even one pointer on an x86_64 machine gave me a
dreaded compiler error:

virstoragetest.c:712:1: error: the frame size of 4208 bytes is larger than 4096 bytes [-Werror=frame-larger-than=]

After some experimentation, I realized that each test was creating
yet another testChainData (which contains testFileData) on the stack;
forcing the reuse of one of these structures instead of creating a
fresh one each time drastically reduces the size requirements.  While
at it, I also got rid of a lot of intermediate structs, with some
macro magic that lets me directly build up the destination chains
inline.

For a bit more insight into what this patch does:
The old code uses an intermediate variable as a fixed-size array
of structs:
testFileData chain[] = { a, b };
data.files = chain;

In the new code, the use of VIR_FLATTEN_* allows the TEST_CHAIN()
macro to still take a single argument for each chain, but now of
the form '(a, b)', where it is turned into the var-args 'a, b'
multiple arguments understood by TEST_ONE_CHAIN().  Thus, the
new code avoids an intermediate variable, and directly provides
the list of pointers to be assigned into array elements:
data.files = { &a, &b };

* tests/virstoragetest.c (mymain): Rewrite TEST_ONE_CHAIN to
reuse the same struct for each test, and to take the data
inline rather than via intermediate variables.
(testChainData): Use bounded array of pointers instead of
unlimited array of struct.
(testStorageChain): Reflect struct change.

Commit 5b3492fa aimed to fix this and caught one error but exposed
another one.  When agent command is being executed and the thread
waiting for the reply is woken up by an event (e.g. EOF in case of
shutdown), the command finishes with no data (rxObject == NULL), but
no error is reported, since this might be desired by the caller
(e.g. suspend through agent).  However, in other situations, when the
data are required (e.g. getting vCPUs), we proceed to getting desired
data out of the reply, but none of the virJSON*() functions works well
with NULLs.  I chose the way of a new parameter for qemuAgentCommand()
function that specifies whether reply is required and behaves
according to that.
