[libvirt] [PATCH v2 00/12] qemu: support hot-plug/unplug RNG device

[Luyao Huang]

qemu already support hot-plug and hot-unplug RNG device.
These patch will make libvirt support hot-plug/unplug RNG device for qemu driver.

v2:
  -remove a commit about add 4 new func in libvirt_private.syms and move them to
   the commit which use these functions
  -impove some commit subject
  -improve the logic in virDomainRNGRemove
  -remove qemuDomainRNGInsert
  -unexport qemuDomainRNGRemove
  -add a check if chardev and backend object ID have the same basic alias name
  -rename need_remove to remove_chardev in qemuDomainAttachRNGDevice
  -add qemu capability check for RNG device backend

Luyao Huang (12):
  qemu: Add helper to assign RNG device aliases
  qemu: refactor qemuBuildRNGDeviceArgs to allow reuse in RNG hotplug
  conf: Introduce function to compare RNG devices.
  conf: add 3 functions for insert,remove and find a RNG device
  qemu: add id when build RNG device and rename object id
  qemu: add a function to remove a RNG device
  qemu: add a functions for attach a rng object in json monitor
  qemu: add 2 functions to attach/detach RNG device via qemu monitor
  audit: export virDomainAuditRNG
  qemu: Implement RNG device hotplug on live level
  qemu: Implement RNG device hotunplug on live level
  tests: fix tests to suit qemu args changes for RNG devices
