Instead of assembling the entire hash-string in the workspace, use
a scatter gather approach, hinted by the VCL compiler.

This eliminates the workspace reservation which prevented regsub() from
working in vcl_hash, and reduces the size of the necessary workspace a
fair bit as well, at the cost of a little bit of complexity in the
hash implmentations.

Closes ticket 137 and possibly 141

operations on the req.hash variable.

It is only a hint, because it merely counts how many times the parser
saw something being added to the req.hash variable.  If the operation
was in a subroutine which was called multiple times, the hint will not
reflect the number of actual operations.

For now we will deal with that at runtime, at the expense of a
failed transaction every time we run short.  If this becomes an issue,
an extensive topological analysis of the VCL program can give us
a definitive count.

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.

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.
