[libvirt] [PATCH v4 00/31] use GNU C's cleanup attribute in src/util (batch I)

This series of patches first introduces a new set of macros which help in using GNU C's __attribute__((cleanup)) in the code. Then a few syntax-check rules are added which help in ensuring correct usage of the newly introduced cleanup macros. Then the patches modify a few files in src/util to use VIR_AUTOFREE and VIR_AUTOPTR for automatic freeing of memory and get rid of some VIR_FREE macro invocations and *Free function calls.
