one bug was traded for another in r1641077; track the response
length and the cached object length separately to avoid such
confusion

The one byte "ok" flag stored with the response was accounted for in
the wrong condition.

Retain num_buckets and max_buckets accross restarts so that we can determine
whether new buckets were allocated and set their idle_spawn_rate at the same
level as the existing ones (max).

Also, adjust ap_daemons_limit and ap_daemons_to_start lower bounds at mpm_run()
time, once num_buckets is available for the current generation (previously done
at pre_config time, hence before num_buckets is computed, and then with the
previous generation's value).

The code changes to mod_authnz_fcgi are retained in order
to keep the similar code in sync between the two modules.
