[libvirt] [PATCH v4 0/5] domainRename API implementation

[Tomas Meszaros]

This is an effort to implement domain rename API. Presented patch series
consists of the following: virDomainRename API implementation for qemu,
implementation of the virsh command domrename and the additional support
code.

The idea behind this endeavor is to provide convenient and safe way to rename
a domain.

Instead of the:

    virsh dumpxml domain > domain.xml
    (change domain name in domain.xml)
    virsh undefine domain
    virsh define domain.xml

user can simply type:

    virsh domrename foo bar

or call virDomainRename() API and domain "foo" will be renamed to "bar".

We currently support only renaming inactive domains without snapshots.
Renaming procedure takes care of domain log, config, guest agent path and should
be able to recover in case of failure.

I've been working on this functionality in collaboration with Michal Privoznik
who is my mentor during the GSoC 2015. If you have any questions, ideas
or criticism feel free to join the discussion.

 - removed guest agent path rename code

v4:
 - removed ATTRIBUTE_UNUSED from the @flags parameter
 - added virCheckFlags() call
 - added flags to the remote_domain_rename_args
