Add switch to gbak to restore database with specified transaction number


 Key: CORE-6121
 URL: http://tracker.firebirdsql.org/browse/CORE-6121
 Project: Firebird Core
  Issue Type: New Feature
  Components: GBAK
Reporter: Karol Bieniaszewski


Please add switch to gbak to restore database with specified transaction number.
E.g. Interbase have this as "-START(ING_TRANS)" the name can be different.
I suppose it is very simple to implement as already during restore Firebird 
start this numbering from 1. Now it should take into account if start it from 1 
or specified value from the parameter.

gbak -c -v -START 123456789

and database after restore looks like
