lib/dbutil: Refactor mysql support, allow relative cert paths.

Refactored mysql configuration flow to allow external code to
populate config structs directly instead of parsing from file.
Added support for relative TLS certificate paths. When parsing
config from file, paths are resolved relative to the directory
containing the config file.
Attempted to remove SQL passwords from error messages.
