  That's how I started but realized that it is much easier just to rename
  all of them with a script. I would personally prefer to rename all enums
  from srdb1 to DB1_INT, DB1_BIGINT and so on, and keep the names from srdb2.

  OK, should I do the db stuff then or do you want to do it? I can take of
  merging it into the master once you merge other changes we will need to
  make that happen, such as all the module compatibility changes.

  Most of us seem to agree on the following list of db changes:

  * preserving history in libraries
  * naming the libraries as srdb1, srdb2
  * renaming conflicting identifiers (db_con1, DB1_INT)
  * merged (with support for versions of the db api) database drivers
  * db_* naming convention for database drivers
  * a script to update modules in ser/kamailio repositories.
