People have been running into the maximum number of headers limitation
more and more lately, so increase this a little bit.  It is a
per-thread overhead, so it should not make any real difference when it
comes to memory consumption.

On Linux, ldconfig needs to be run after installing shared libraries
to system paths (typically /usr/local/lib, /usr/lib and /lib).
Document this.

by sharing most of the code with the "random" director.

The Hash director will use the hash output from vcl_hash{} to pick a
backend from the configured set.

If this backend is unhealthy, it pick another backend, using only the
healthy subset of backends, but as soon as the "canonical" backend becomes
healthy it will revert to using that.

This means that one backend going unhealthy on "rehashes" the requests for
that backend, hashing for healthy backends are not affected.

hash available for other uses.

Remove the backend deref code that is no longer needed by random/round-robin
directors, since they only reference other directors in the same VCL.

Stop messing with sp->vbe behind the back, make the assignment explicit
where it matters.

Move the "simple" director into cache_backend.c, since it is what
is really dealing with backends now that directors are objectified.

Make a lot of stuff static as a result.

Collect both the init and fini VRT functins for directors in
cache_backend_cfg.c

The documentation referred to deprecated url.purge, make it point to
purge.url instead.  Maybe it should be updated to the new purge
syntax.

This was originally a quick hack to allow purging to take the Host:
header into account.

We have a much better and precisely expressive purge syntax now, so
this hack can die.
