Add functions in C to operation id computations
Use new functions in sql-serializer
Use new C functions in hive_fork_manager sql scripts
	- Warning: additional wrrapers added because the
	  functions are used by indexes (part of data schema), and 'C'
	  functions are part of runtime deployment, so they are unknow
	  during data installation

operation_id

hive.operation_id is used now to compute stable id for sorting
keyauth changes. The computed id guarantees that change caused by a
harfork are lates in a hardfork block.

Wrappers where introduced to be use be indexes during instalation data
schema and runtime must use exactly the same functions
to allow planner to use indexes, what was not implemented when wrapper
were added.

postgres by defualt sets COST to 100 for plpgsql functions, and 1 for
calling C functions, because the wrappers only directly call C functions it
is better to inform planner about their low cost.

indexed which are using expressions needs to be ANALYZE-d, otherwise planner will chose wrong executions plans, because there are nostatistics for the expressions
