For the new VIR_DOMAIN_EVENT_ID_TUNABLE event we have a bunch of
constants added
VIR_DOMAIN_EVENT_CPUTUNE_<blah>
VIR_DOMAIN_EVENT_BLKDEVIOTUNE_<blah>
This naming convention is bad for two reasons
- There is no common prefix unique for the events to both
relate them, and distinguish them from other event
constants
- The values associated with the constants were chosen
to match the names used with virConnectGetAllDomainStats
so having EVENT in the constant name is not applicable in
that respect

VIR_DOMAIN_TUNABLE_BLKDEV_<blah>

The network and nwfilter drivers both have a need to update
firewall rules. The currently share no code for interacting
with iptables / firewalld. The nwfilter driver is fairly
tied to the concept of creating shell scripts to execute
which makes it very hard to port to talk to firewalld via
DBus APIs.
This patch introduces a virFirewallPtr object which is able
to represent a complete sequence of rule changes, with the
ability to have multiple transactional checkpoints with
rollbacks. By formally separating the definition of the rules
to be applied from the mechanism used to apply them, it is
also possible to write a firewall engine that uses firewalld
DBus APIs natively instead of via the slow firewalld-cmd.

The nwfilter ebiptables driver will build up commands to run in
two phases. The first phase contains all of the command, except
for the '-A' part. Instead it has a '%c' placeholder, along with
a '%s' placeholder for a position arg. The second phase than
substitutes these placeholders. The only values ever used for
these substitutions though is '-A' and '', so it is entirely
pointless. Remove the second phase entirely, since it will make
it harder to convert to the new firewall APIs

The current nwfilter tech driver API has a 'createRuleInstance' method
which populates virNWFilterRuleInstPtr with a command line string
containing variable placeholders. The 'applyNewRules' method then
expands the variables and executes the commands. This split of
responsibility won't work when switching to the virFirewallPtr
APIs, since we can't just build up command line strings. This patch
this merges the functionality of 'createRuleInstance' into the
applyNewRules method.
The virNWFilterRuleInstPtr struct is changed from holding an array
of opaque pointers, into holding generic metadata about the rules
to be processed. In essence this is the result of taking a linked
set of virNWFilterDefPtr's and flattening the tree to get a list
of virNWFilterRuleDefPtr's. At the same time we must keep track of
any nested virNWFilterObjPtr instances, so that the locks are held
for the duration of the 'applyNewRules' method.
