[libvirt] [PATCH v4 0/9] Implement Add/Del IOThreads

[John Ferlan]

v3 here:
http://www.redhat.com/archives/libvir-list/2015-April/msg00621.html

Changes since v3

Patch 1:
 * Add back in and use virDomainIOThreadIDDefFree
 * Change _virDomainIOThreadIDDef 'undefined' to 'autofill'
 * Adjust virDomainDefParseXML to only allocate what's defined
   allowing virDomainDefPostParseInternal to Add in IOThreads
   which weren't defined and set the 'autofill' boolean
 * Have virDomainIOThreadIDAdd return a virDomainIOThreadIDDefPtr

Patch 2: No changes

Patch 3: (NEW)
 * Discussed in prior review regarding making virDomainPinIsDuplicate
   a static function (needed to move it)

Patch 4: (NEW)
 * Move the iothreadspin data (e.g., the cpumask) into _virDomainIOThreadIDDef
 * Kept the 'niothreadspin' and manipulated as necessary since there was code
   to write out <cputune> data that I didn't want to reinvent/rototill just
   to search through iothreadids for a cpumask
 * Adjusted virDomainIOThreadPinDefParseXML to handle storing the cpumask
   in the right iothreadsid[] entry.  If not found (it may not be since the
   virDomainDefPostParseInternal hasn't run), then create an autofill version
   of an iothreadids entry.
 * Remove/adjust a lot of code that used to handle iothreadspin

Patch 5: (NEW)
 * Slight adjustment for iothreadsched to allow for "any" id value. This
   code stores iothread id's as bitmap entries, so it didn't have the same
   issues as the iothreadspin code

Patch 6-7: Unchanged

Patch 8:
 * Adjusted the search for the new thread code to use existing alias
 * Use the virDomainIOThreadIDAdd returned pointer
 * Comment adjustments from code review
 * Removal of erroneously cut-n-pasted code in Delete path
 * Use the ->dst for the message
 * Changes based on having cpumask in the iothrid data

Patch 9: No changes
