inotail: Support reopening rotated files
We changed the behaviour of the "follow" option so that it detects that file has been moved or deleted it keeps monitoring for the file instead of ignoring it. This is useful when tailing syslog circular logs, where syslog periodically moves the log to another filename and recreates the log file. Without the patch inotail would issue a "file has been moved" or a "file has been deleted message" and stop tracking the file. Now it will close the file and refresh the inotify +descriptor. When a notification arrives with a CREATE or MODIFY event, it will reopen the file and set the size to zero. We are using the patched program in an embedded ARM system with satisfactory results.
