So that variables only used within SAL_INFO/WARN do not lead to
unused variable warnings in product builds.  Also for OSL_TRACE
(which used to work that way before already); allowing to revert
a recent warning fix.

* New SAL_INFO..., SAL_WARN... macros.
* New SAL_STREAM supersedes OSL_FORMAT.
* oustringostreaminserter.hxx moved from unotest to rtl (and always UTF-8 now).
* TODO to enable GCC __attribute__((format)) in sal/log.h (requires call-site
  cleanup).
* Further functionality in tools/debug.hxx (DBG_MEMTEST, DBG_CTOR, etc.) not yet
  addressed.
* Some replacements tools String -> rtl::OUString.

Some 3rd party (Russian?) programs generate broken xls docs which
cause Calc to hang when it tries to open it.  This particular doc
placed invalid record at position indicated by BOUNDSHEET, where BOF
was expected.  Let's skip those invalid records.

Or else the pTokenMatrixMap would never yield any match.  This was
the only reason behind the poor performance of resolving jump matrix
as exhibited in the aforementioned bug...

This updates the keys for the following intentional changes:

ENUM: /UCR/com/sun/star/drawing/TextFitToSizeType
  Field 3: Name1 = RESIZEATTR  !=  Name2 = AUTOFIT
SERVICE: /UCR/com/sun/star/sheet/SpreadsheetViewSettings
  SERVICE1 contains 1 more properties as SERVICE2
  incompatible change: Field 14 ('SolidHandles') of r1 is not longer a property of this SERVICE in r2
SERVICE: /UCR/com/sun/star/text/ViewSettings
  SERVICE1 contains 1 more properties as SERVICE2
  incompatible change: Field 24 ('SolidMarkHandles') of r1 is not longer a property of this SERVICE in r2

Function checkField() is called from 2 different contexts, one of
which must not report errors, but the other should.
