Since the introduction of the virNetworkPort object, the network driver
has a persistent record of ports that have been created against the
networks. Thus the hypervisor drivers no longer communicate to the
network driver during libvirtd restart.

This change, however, meant that the connection usage counts were
no longer re-initialized during a libvirtd restart. To deal with this we
must iterate over all virNetworkPortDefPtr objects we have and invoke
the notify callback to record the connection usage count.

Missing semicolon at the end of macros can confuse some analyzers
(like cppcheck <filename>). VIR_ONCE_GLOBAL_INIT is almost
exclusively called without an ending semicolon, but let's
standardize on using one like the other macros.

Add a dummy struct definition at the end of the macro, so
the compiler will require callers to add a semicolon.

We have this very handy macro called VIR_STEAL_PTR() which steals
one pointer into the other and sets the other to NULL. The
following coccinelle patch was used to create this commit:

  @ rule1 @
  identifier a, b;
  @@

  - b = a;
    ...
  - a = NULL;
  + VIR_STEAL_PTR(b, a);

Some places were clean up afterwards to make syntax-check happy
(e.g. some curly braces were removed where the body become a one
liner).

So far we are repeating the following lines over and over:

  if (!(virSomeObjectClass = virClassNew(virClassForObject(),
                             "virSomeObject",

      return -1;

While this works, it is impossible to do some checking. Firstly,
the class name (the 2nd argument) doesn't match the name in the
code in all cases (the 3rd argument). Secondly, the current style
is needlessly verbose. This commit turns example into following:

  if (!(VIR_CLASS_NEW(virSomeObject,
                      virClassForObject)))

Back in the day when I was implementing QoS for networks there
were no self inflating virBitmaps. Only the static ones.
Therefore, I had to allocate the whole 8KB of memory in order to
keep track of used/unused class IDs. This is rather wasteful
because nobody is ever gonna use that much classes (kernel
overhead would drastically lower the bandwidth). Anyway, now that
we have self inflating bitmaps we can start small and allocate
more if there's need for it.
