openldap/servers/slapd/back-sql/modify.c
Pierangelo Masarati 115408986c changes:
- re-style according to the style giudelines for better readability
- updated to recent frontend/backend API changes
- fixed a few quirks about normalization
- "optimized" a few memory allocation/string handling functions
- fixed a few quirks about add/modify (still have to look ad modrdn)

todo:
- there is still something broken (at least with PostgreSQL and IBM db2,
  the two RDBMS O have at hand) when adding
- move everything to struct bervals and try to save a few strlen
- try some LDAP/SQL syntax relation to use appropriate value bind if possible
- ...
