sql/sp_head.cc:
  Code cleanup patch from Monty: 
  in subst_spvars()
  - Move local variables first in block
  - Use res|= instead of res |=
  - Use strmake() instead of alloc + memcpy
  Added:
  - Fail the query if we don't have enough memory to produce a binlog-suitable query string: 
    if we're so low on memory we're likely to fail the query anyway, and failing now removes
    the need for hack with THD::query_str_binlog_suitable.
