imfile improvements
- added the $InputFilePersistStateInterval config directive to imfile - changed imfile so that the state file is never deleted (makes imfile more robust in regard to fatal failures)

+Specifies how often the state file shall be written when processing the input
+file. The default value is 0, which means a new state file is only written when
+the monitored files is being closed (end of rsyslogd execution). Any other
+value n means that the state file is written every time n file lines have
+been processed. This setting can be used to guard against message duplication due
+to fatal errors (like power fail). Note that this setting affects imfile
+performance, especially when set to a low value. Frequently writing the state
+file is very time consuming.
