forward RTL_CONTEXT_foo logging to SAL_INFO in default debugging

[Tor Lillqvist]

I am more and more starting to be of the opinion that all debugging
printouts, SAL_INFO() (or RTL_foo)  are mostly useless once the bug or
misfeature you have been chasing (for which you have added the
debugging logging) has been found and fixed;)

If and when later some other bug in the same area needs chasing, you
will have to add more SAL_INFOs, or add more information to existing
ones, anyway... I.e. there is no effective difference between SAL_INFO
and SAL_DEBUG.
