ajp13 and tomcat restart - next (final) release

[GOMEZ Henri]

Hi,

You could find here the latest patch for ajp13/mod_jk
when tc is restarted.

Seems fine and ready to be commited.

PS: I'll add timestamp in mod_jk logs but I'd like
    also to remove the datasync in log since it's just
    to much I/O consuming in debug mode (Ok ?)
