Missing semicolon at the end of macros can confuse some analyzers

Since we're setting the zone anyway, it will be useful to allow
setting a different (custom) zone for each network. This will be done
by adding a "zone" attribute to the "bridge" element, e.g.:

   ...
   <bridge name='virbr0' zone='myzone'/>
   ...

If a zone is specified in the config and it can't be honored, this
will be an error.

'val' is initialized from virDomainCapsFeatureTypeFromString and a
few lines earlier there was already a check for 'val < 0'.

The 'val >= 0' is thus always true. The enum conversion similarly
ensures that the val will be less than VIR_DOMAIN_CAPS_FEATURE_LAST,
so "val < VIR_DOMAIN_CAPS_FEATURE_LAST' is thus always true too.

Introduce the infrastructure necessary to manage a Storage Pool XML
Namespace. The general concept is similar to virDomainXMLNamespace,
except that for Storage Pools the storage backend specific details
can be stored within the _virStoragePoolOptions unlike the domain
processing code which manages its xmlopt's via the virDomainXMLOption
which is allocated/passed around for each domain.

This patch defines the add the parse, format, free, and href methods
required to process the XML and callout from the Storage Pool Def
parse, format, and free API's to perform the action on the XML data
for/from the backend.

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);

(e.g. some curly braces were removed where the body become a one
