s4-dsdb: Add context structure for dsdb_syntax conversion functions

This structure is intended to hold context-dependent data.

Syntax-conversion and object-conversion functions need
that data to convert objects and attributes from drs-to-ldb
and ldb-to-drs correctly.

For instance: ATTID value depends on whether we are converting
object from partition different that Schema partition.
