the SMA to run out of space eventually.

If we were panic-ing in multiple threads at the same time, the panic
buffer would be partially overwritten.  Prevent this with a mutex

When we pushed the object allocation into the stevedores for
-spersistent, we did not add LRU eviction to that allocation
path.

Then we added the Transient storage as a fallback for objects
we could not allocate, and they all went there.

Change the way object allocation works as follows:

        If VCL set a stevedore hint and it is valid, we stick
        with it, and LRU that stevedore attempting to make space.

        If no valid hint is given, try all stevedores in turn,
        then LRU one of them to make space.

The ABI we give vmods consist of the Varnish version number and the
git commit ID meaning we can break ABI at will.
