new upstream release

Update monit to 5.7
> CHANGES version 5.7
> This file summarizes changes made since 5.0
> Version 5.7
> 
> New: Merged https://bitbucket.org/tildeslash/monit/pull-request/1/
> from Philippe Kueck:
> 1) Handle sockets (unix domain) as regular files when checking timestamp.
> 2) Use mysql 4.1 protocol in MySQL check, required for checking mysql-proxy
> 3) Skip connection checks during startup timeout.
> 
> New: Arguments added to 'check program'. Arguments are whitespace
> separated strings. For instance:
> 
>   check program list-files with path "/bin/ls -l -r -t /tmp"
>         if status != 0 then alert
> 
> New: Implemented restart as an optional service action. When Monit
> is called to restart a service, it previously called the stop
> program registered with the service and then the start program.
> Now, if a restart program is registred with the service, this
> will be called instead, otherwise Monit fall back to its old
> behaviour. Example:
>      
>   check process apache with pidfile /var/run/httpd.pid
>         start   = "/usr/sbin/apachectl start"
>         stop    = "/usr/sbin/apachectl stop"
>         restart = "/usr/sbin/apachectl restart" <- New
> 
> New: Improved communication with M/Monit. Thanks to Hippo Lin. For 
> scalability purpose, this Monit version should only be used with
> M/Monit version 3.1 or later.
