Description:
------------
When configuring the FPM, a config option like

user = 12345

is valid, but

listen.owner = 12345

provokes a 'cannot get uid for user' error message

The code to be fixed is in sapi/fpm/fpm/fpm_unix.c where fpm_unix_conf_wp() has a check for a numerical value but fpm_unix_resolve_socket_premissions() [which looks like a typo to me] hasn't.

I added a simple patch to port this functionality to fpm_unix_resolve_socket_premissions(); if this will be accepted, a similar change might be favorable for the acl options, too.

Background: This helps to avoid getpwnam() in situations with a not-so-stable LDAP server...
