PCO Vers. 1.0.1 - Split of the low level database access

Added separate folders (itzam, sqlite, rawdb) under src, for specific database access implementations.
Default database : itzam.
Use "./configure --with-sqlite" to build using the SQLITE db. Provide implementation in src/sqlite/pers_low_level_db_access.c
based on pers_low_level_db_access_if.h
Use "./configure --with-rawdb" to build using the RAWDB db.  Provide implementation in src/rawdb/pers_low_level_db_access.c
based on pers_low_level_db_access_if.h
