- count() returns very different results and never a boolean (not even false on
  error condition).
- therefore you should NOT use it in boolean expressions. This still *can* be
  done in PHP because of its lazyness. But it is discouraged if it comes to
  more clean code.

- use dba::is_result() everywhere (where I found the old, bad way)
- converted some spaces -> tabs for code
- converted some CRLF -> LF as mixures of both is not good

This reverts commit db949bb802.

Only define functions if they have not been defined before, e.g. in themes. This makes it possible to override parts of a module and still use the other functions.
