Use PHP FPM instead of ancient Spawn-FCGI

Use the default FPM config, except the max_children, which is set to 10
as it was with spawn-fcgi.

+; List of ipv4 addresses of FastCGI clients which are allowed to connect.
+; Equivalent to the FCGI_WEB_SERVER_ADDRS environment variable in the original

+; Set permissions for unix socket, if one is used. In Linux, read/write

+
+; The URI to view the FPM status page. If this value is not set, no URI will be

+;   idle processes       - the number of idle processes;
+;   active processes     - the number of active processes;
+;   total processes      - the number of idle + active processes.
+;   max children reached - number of times, the process limit has been reached,
+;                          when pm tries to start more children (works only for
+;                          pm 'dynamic')
+; The values of 'idle processes', 'active processes' and 'total processes' are
+; updated each second. The value of 'accepted conn' is updated in real time.

+;   active processes:     65
+;   total processes:      100
+;   max children reached: 1
+; By default the status page output is formatted as text/plain. Passing either
+; 'html' or 'json' as a query string will return the corresponding output
+; syntax. Example:
+;   http://www.foo.bar/status
+;   http://www.foo.bar/status?json
+;   http://www.foo.bar/status?html
+; Note: The value must start with a leading slash (/). The value can be
+;       anything, but it may not be a good idea to use the .php extension or it
+;       may conflict with a real PHP file.
+; Default Value: not set 
+;pm.status_path = /status
+ 
+; The ping URI to call the monitoring page of FPM. If this value is not set, no
+; URI will be recognized as a ping page. This could be used to test from outside
+; that FPM is alive and responding, or to
+; - create a graph of FPM availability (rrd or such);
+; - remove a server from a group if it is not responding (load balancing);
+; - trigger alerts for the operating team (24/7).
+; Note: The value must start with a leading slash (/). The value can be
+;       anything, but it may not be a good idea to use the .php extension or it
+;       may conflict with a real PHP file.
+; Default Value: not set
+;ping.path = /ping
+
+; This directive may be used to customize the response of a ping request. The
+; response is formatted as text/plain with a 200 response code.
+; Default Value: pong
+;ping.response = pong
+ 
+; The timeout for serving a single request after which the worker process will
+; be killed. This option should be used when the 'max_execution_time' ini option
+; does not stop script execution for some reason. A value of '0' means 'off'.
+; Available units: s(econds)(default), m(inutes), h(ours), or d(ays)
+; Default Value: 0
+;request_terminate_timeout = 0
+ 
+; The timeout for serving a single request after which a PHP backtrace will be
+; dumped to the 'slowlog' file. A value of '0s' means 'off'.

+; Default Value: not set
+; Note: slowlog is mandatory if request_slowlog_timeout is set
+;slowlog = log/$pool.log.slow

+; Set open file descriptor rlimit.
+; Default Value: system defined value
+;rlimit_files = 1024
+ 
+; Set max core size rlimit.
+; Possible Values: 'unlimited' or an integer greater or equal to 0
+; Default Value: system defined value
+;rlimit_core = 0
+ 
+; Chroot to this directory at the start. This value must be defined as an
+; absolute path. When this value is not set, chroot is not used.
+; Note: you can prefix with '$prefix' to chroot to the pool prefix or one
+; of its subdirectories. If the pool prefix is not set, the global prefix
+; will be used instead.
+; Note: chrooting is a great security feature and should be used whenever 
+;       possible. However, all PHP paths will be relative to the chroot
+;       (error_log, sessions.save_path, ...).
+; Default Value: not set
+;chroot = 
+ 
+; Chdir to this directory at the start.
+; Note: relative path can be used.
+; Default Value: current directory or / when chroot
+chdir = /
+ 
+; Redirect worker stdout and stderr into main error log. If not set, stdout and
+; stderr will be redirected to /dev/null according to FastCGI specs.
+; Note: on highloaded environement, this can cause some delay in the page
+; process time (several ms).
+; Default Value: no
+;catch_workers_output = yes
+ 
+; Pass environment variables like LD_LIBRARY_PATH. All $VARIABLEs are taken from
+; the current environment.
+; Default Value: clean env
+;env[HOSTNAME] = $HOSTNAME
+;env[PATH] = /usr/local/bin:/usr/bin:/bin
+;env[TMP] = /tmp
+;env[TMPDIR] = /tmp
+;env[TEMP] = /tmp
+
+; Additional php.ini defines, specific to this pool of workers. These settings
+; overwrite the values previously defined in the php.ini. The directives are the
+; same as the PHP SAPI:
+;   php_value/php_flag             - you can set classic ini defines which can
+;                                    be overwritten from PHP call 'ini_set'. 
+;   php_admin_value/php_admin_flag - these directives won't be overwritten by
+;                                     PHP call 'ini_set'
+; For php_*flag, valid values are on, off, 1, 0, true, false, yes or no.
+
+; Defining 'extension' will load the corresponding shared extension from
+; extension_dir. Defining 'disable_functions' or 'disable_classes' will not
+; overwrite previously defined php.ini values, but will append the new value
+; instead.
+
+; Note: path INI options can be relative and will be expanded with the prefix
+; (pool, global or /usr)
+
+; Default Value: nothing is defined by default except the values in php.ini and
+;                specified at startup with the -d argument
+;php_admin_value[sendmail_path] = /usr/sbin/sendmail -t -i -f www@my.domain.com
