This makes changing runtime paramters work again, without the need to
ask for a nonexistent parameter to trigger the update.

Made it possible to pass a vcl variable to error (error 200 backend.health).
Implemented a first attempt at an algorithm for checking the health of a backend. 
Negative values means the backend has problems, positive values means it is ok. 0 is neutral,
and could mean that it has been a while since the backend was asked for anything.
See the code for details.

to an unsigned int (which triggered warnings on some 64-bit platforms) and
printed with %08lx, incorrectly assume that it can be meaningfully cast to
a void * and printed with %p.  While still incorrect in general terms, the
latter turns out to be correct on the specific systems that we care about.

one stevedore to the next.  The LRU code is invoked as soon as any of the
stevedores fills up.

This algorithm is far from ideal, and will not work well with differently
sized stevedores, but it has the advantage of being simple and lock-free.
