separated out most mysql specific code to mod_log_sql_mysql.c
beginnings of separation of core SQL logging logic moved DB connection paramters to a table (for cutoms params for DB drivers) added new configuration directive to handle any DB parameter renamed all log_sql_* vars and type to logsql_* Added enums for opendb return codes. organized config directives and commented for easier reading of source
