Options

Enabled usage of new system variables for ndb 

  - ndb_use_exact_count
  - ndb_autoincrement_prefetch_sz
  - ndb_use_transactions
  - ndb_force_send
moved "inlined" functions to .cc file since they are virtual anyways
enabled printout od ndb errors in warnings even if mapping existst to mysql error code
