[libvirt] [PATCH 0/2] Add lock in libxl

These two patches implement a lock for long-running job(save, dump and migration) and normal job which will return in short time but maybe affect the state of virtual machine. With these patches, the normal job could not execute while the long-ruuning job or other normal job is running. In order to tracking these job, job type for normal job and long-ruuning job(will be called as async job in code) is defined. The abort job is called while user want to cancel such async job. Note that there is no cancellation function for async job in xenlight stack. So, abort function just block the cancellation of user. Update compare to v1: 1, remove migration relative job functions from lock patch. 2, update comments according to upstream's comments.
