[libvirt] [PATCH v1 13/21] util: auth: use VIR_AUTOPTR for aggregate types

[Sukrit Bhatnagar]

By making use of the GCC's __attribute__((cleanup)) handled by VIR_AUTOPTR
macro, majority of the calls to *Free functions can be dropped, which in
turn leads to getting rid of most of our cleanup sections.
