C90 support (was: Variadic Debug() macro)

I think it is time to modernise the debug logging a bit, this would make our life easier when logging and running make (with the copious warnings compilers will generate unless one passes -Wno-format-extra-args).

The major obstacle to this is the thousands of lines that need adjusting, (...)

The obstacle is that we support building OpenLDAP with C90 compilers.

If we ditch that and require a C99 compiler, we can kill annoyances like Debug() extra args. IIRC the answer has been "sigh, not yet" for a long time, I don't remember if it still was last time we talked about it.

(We can still have headers which support C90, so people only need C99 for building.)
