Based on Lubos's comments, I changed this once again, incompatibly:

* sal/log.h is now sal/log.hxx, and can thus only be used from C++ code. 
  If we need it in a file that is still C, change that file to C++ 
first.  (I see almost no need for any pure C files in LO at all.  That 
many implementation files in, e.g., sal are written in C is a historic 
relic that can and should be fixed; I already did that recently for 
sal/source/rtl.  The stable C header files in the URE interface are a 
different thing, of course.)

* The _S suffix is dropped from the logging macros using streaming, and 
the format-string variants are gone.  A compile time check ensures the 
common case of streaming just a plain C-style string literal still 
produces reasonably compact call-site code.

* The format-string variants are still available in sal/detail/log.h, 
but only to be used in obsolete osl/diagnose.h etc., and going to be 
removed again eventually.

I noticed this change will break non-clean builds in odk, "cd odk && rm 
-rf ${INPATH?}" should help.
