TrackedOp: remove the init_from_message function

I'm not sure why we ever had this instead of just doing things in the
subclass constructor, and the semantics around it don't make much sense
for anything else (we called mark_event first anyway).

TrackedOp: rename arrived_at to initiated_at, specify when constructed

Instead of relying on the message's get_recv_stamp, take a timestamp
when the TrackedOp is constructed. Rename get_received_at() -> get_initiated().

Further parameterize the template to allow passing in an arbitrary parameter,
and move all the Message-based event marking from there into OpRequest.

mds: properly clear new flag for stale client cap

CInode::encode_inodestat() should clear the 'new' flag of client

pass '-classpath' option (gcj/javah ignores CLASSPATH environment variable).

 This should not affect OpenJDK which understands '-classpath' as well.

 With gcj-jdk we still get FTBFS later:
