This patch adds a new variable maxQueuedJobs into the job object
as it is the last hypervisor-based part of the begin job. Since
this patch, it will not be necessary to propagate driver
structure into the job functions.

The virMacMap module is used only for libvirt_guests NSS module
as it records list of MAC addresses used by certain guest. But
the module itself is usable if and only if the network assigns IP
addresses (i.e. has dnsmasq running). If it's some other
authority that assigns IP addresses then we do not need the
virMacMap module at all.
For instance, a network with no <forward/> type and no DHCP set
won't create /var/lib/libvirt/dnsmasq/ dir which is what the
module expects to exist. But there's no need for the module to
even care about such network.

Currently, whenever virNetworkObjSetMacMap() is called the same
pattern is used:
1) call virMacMapFileName() to generate a filename,
2) pass this filename to virMacMapNew(), and finally
3) pass retval from previous step to virNetworkObjSetMacMap().
Move this code into a helper (networkSetMacMap()) and replace
both pattern occurrences with its call.

The virNetworkObjSetMacMap() API effectively steals passed
@macmap argument. However, the argument is a plain, first order
pointer. This requires every caller to set the argument to NULL
after the function was called. Let's make the function take
double pointer instead to make it obvious that the argument is
consumed.

The networkStartNetworkVirtual() function handles starting of
networks of different forward types (none, nat, route, open).
And as a part of startup process dnsmasq might be spawned but
doesn't have to be (depending on the network configuration). The
@dnsmasqStarted variable is supposed to track whether dnsmasq was
started or not (so that it can be killed when starting network
fails after it was started). But the variable is set even when
the code decided not to start it.

This fixes vircryptotest on macOS 12 (Monterey).
The test relies on library injection (using DYLD_INSERT_LIBRARIES)
to replace the normal random functions with functions giving predictable
results, defined in virrandommock.c. However, using DYLD_INSERT_LIBRARIES
only works when building with flat namespaces.
Adding the -Wl,-flat_namespace option to the linker fixes the problem.
The option was already defined in the top-level meson.build, but had been
forgotten in the test linker arguments.

It should be enough to enable or disable the enrolled-keys feature
to control whether Secure Boot is enforced, but there's a slight
complication: many distro packages for edk2 include, in addition
to general purpose firmware images, builds that are targeting the
Confidential Computing use case.
For those, the firmware descriptor will not advertise the
enrolled-keys feature, which will technically make them suitable
for satisfying a configuration such as
<os firmware='efi'>
<firmware>
<feature state='off' name='enrolled-keys'/>
</firmware>
</os>
In practice, users will expect the general purpose build to be
used in this case. Explicitly asking for the secure-boot feature
to be enabled achieves that result at the cost of some slight
additional verbosity.
