Use strncpy() instead of strcpy and make sure the result
is '\0' terminated.
Fix for:
CID 1063700 (#1 of 1): Copy into fixed size buffer (STRING_OVERFLOW)
fixed_size_dest: You might overrun the 4088 byte fixed-size string
vol_args.name by copying the return value of c_str without checking
the length.

shutdown() resets initialized to 0, but we can still receive messages
after this point, so fix message handlers to skip messages in this
case instead of asserting.
Also read initialized while holding Objecter::rwlock to avoid races
where e.g. handle_osd_map() checks initialized -> 1, continues,
shutdown() is called, sets initialized to 0, then handle_osd_map()
goes about its business and calls op_submit(), which would fail the
assert(initialized.read()) check. Similar races existed in other
message handlers which change Objecter state.
The Objecter is not destroyed until after its Messenger in
the MDS, OSD, and librados, so this should be safe.

Fix two other paths where may change the mon state so that we wait for the

almost any time if we see an election message from another mon.

The ctime changes any time the inode does. That can happen even without
the file itself having changed, so we'd better accept the update whenever
the auth caps have dirtied, without worrying about the file caps!

following sequence events may happen.
- client sends reconnect message to a recovering MDS.
- MDS::ms_verify_authorizer() create a session for the client, the
session is in closed state.
- MDS::handle_client_reconnect() sends session close message to
the client.
- client closes the old connection and opens a new connection
- MDS::ms_verify_authorizer() is called for a new connection
- MDS::ms_handle_reset() is called for the old connection
- MDS::ms_handle_accept() is called for the new connection
MDS::ms_handle_reset() removes client's session from the session map, this
can cause null pointer dereference when handling client request. The fix
is add session to sessionmap when its state becomes 'opening' and remove
session from sessionmap when its state becomes 'closed'
