added new transaction state: s_waiting_for_replayers

Browse Source 
to make it posisble to diagnose from outside, if potential
BF victim transaction is blocked in replayer wait loop (before entering commit phase).
Also, added new forced state change to s_must_abort, if before_rollback() is used
for a transaction in s_committing state. Such situation can happen, if BF abort happens
for a victim, which has passed certification and moved to commit phase before the BF aborting happens.
