Bug description:Allow zero pm.start_servers/pm.min_spare_servers

Description:
------------
We are currently implementing PHP-FPM in a shared hosting environment. We
have many users on one server (about 200) and we have to define one pool
for each customer (each with a different uid).
If PHP-FPM starts one children per customer at startup, this would kill the
servers, I think.
So we have to start them on demand. When using PHP via mod_fcgid/suEXEC you
can define FcgidMinProcessesPerClass 0, which works fine, but in PHP-FPM
this is not allowed.

I tried to remove the check in fpm_conf.c:
  if (config->pm_min_spare_servers <= 0)
  if (config->pm_start_servers <= 0)

but this does not really work (zero children are created at startup which
is fine, but no child is created on request and the request hangs). I
currently don't find the right entry point.
