For historical reasons data regarding NUMA configuration were split
between the CPU definition and numatune. We cannot do anything about the
XML still being split, but we certainly can at least store the relevant
data in one place.
This patch moves the NUMA stuff to the right place.
As virDomainNumatuneSet now doesn't allocate the virDomainNuma object
any longer it's not necessary to pass the pointer to a pointer to store
the object as it will not change any longer.
While touching the parameter definitions I've also changed the name of
the parameter to "numa".
Since our formatter now handles well if the config is allocated and not
filled we can safely always-allocate the NUMA config and remove the
ad-hoc allocation code.
This will help in later patches as the parser will be refactored to just
fill the data.
It's easier to recalculate the number in the one place it's used as
having a separate variable to track it. It will also help with moving
the NUMA code to the separate module.
Name it virNumaMemAccess and add it to conf/numa_conf.[ch]
Note that to avoid a circular dependency the type of the NUMA cell
memAccess variable was changed to int. It will be turned back later
after the circular dependency will not exist.
For weird historical reasons NUMA cells are added as a subelement of
<cpu> while the actual configuration is done in <numatune>.
This patch splits out the cell parser code from cpu config to NUMA
config. Note that the changes to the code are minimal just to make it
work and the function will be refactored in the next patch.
For a while now there are two places that gather information about NUMA
related guest configuration. While the XML can't be changed we can at
least store the data in one place in the definition.
Rename the numatune_conf.[ch] files to numa_conf as later patches will
move the rest of the definitions from the cpu definition to this one.
