remove SET_VAR_REQ,REF,CONF - unused, #if 0 and confusing

Remove the dead SET_VAR_REQ,REF,CONF signals.

They:
a) don't currently work
b) will cause confusion with future mgmd updates for
   signal interface to configuration things (e.g. port numbers)

remove GSN_STATISTICS_REQ and CONF

These are unused and have been since BK import. not needed.

Don't send uninit data in TAMPER_ORD to DIHNDBTAMPER

Even though this data is unused from the CMVMI (mgmd) signal,
we shouldn't be doing stuff with uninited data.

there is backwards compatibility for GET CONFIG style configuration requests in
ndb_mgmd. None of the ndbd versions that use this couldn't possibly connect to a
5.0 or 5.1 cluster. remove the backwards compat

remove it

indicate units in SocketOutputStream timeout

rename timeout in SocketOutputStream to reflect units (ms)

In 5.0 as well as is safe cleanup patch that will help with merging.
