In this patchset I'm switching from virXXXFree to g_autoptr(). There are
still some left, but very rare occurrence:
libvirt.git $ git grep -o "vir[A-Z].*Free" -- tools/ | \
cut -d':' -f 2 | sort | uniq -c | sort -n
And of course, after these some functions could use subsequent cleanup,
e.g. because cleanup label collapsed to just return statement. But I
leave those for future work.

New subject: [PATCH 1/8] virsh-util.h: Fix ordering of virshXXXFree functions
Currently the order of virshXXXFree functions in the header file
does not correspond to the order in the corresponding .c file.

In this patchset I'm switching from virXXXFree to g_autoptr(). There are
still some left, but very rare occurrence:
libvirt.git $ git grep -o "vir[A-Z].*Free" -- tools/ | \
cut -d':' -f 2 | sort | uniq -c | sort -n
And of course, after these some functions could use subsequent cleanup,
e.g. because cleanup label collapsed to just return statement. But I
leave those for future work.
