Up until now we have only formatted non-default GIC versions on
the command line, in order to maintain compatibility with older
QEMU versions that didn't implement the gic-version option to
begin with; however, doing so is entirely unnecessary for newer
QEMU versions, where the option is available. Moreover, having
the GIC version formatted on the command line at all times
ensures that QEMU changing its own defaults doesn't affect the
ABI of libvirt guests.

A few test cases are removed to avoid extra churn. It doesn't
matter for coverage, as those scenarios are already covered by
other parts of the test suite.

This patch is better viewed with 'git show -w'.

This is the responsability of the caller to apply the correct lock
before using these functions. Moreover, the use of a simple boolean
was still racy: two threads may check the boolean and "lock" it
simultaneously.

Users of functions from src/util/virhash.c have to be checked for
correctness. Lookups and iteration should hold a RO
lock. Modifications should hold a RW lock.

Most important uses seem to be covered. Callers have now a greater
responsability, notably the ability to execute some operations while
iterating were reliably forbidden before are now accepted.
