Removed uses of rtl::O[U]String[Buffer]::operator sal_{char|Unicode} const *() in Mac OS X only code.

Added #include "unotest/oustringostreaminserter.hxx" back in (will be needed once rtl::OUString::operator sal_Unicode const *() is removed); made tools explicitly depend on unotest.

Fixes warnings: 'SvXML*_Impl' declared with greater visibility than
the type of its field 'SvXMLExport_Impl::mpRDFaHelper'.

Bug 38831, replace SvULongs with std::vector in sfx2 and related svtools

Replace SvULongs with std::vector<sal_uIntPtr> and SvUShorts with std::vector<sal_uInt16>

Reduce scope of variables declared inside a switch statement. OK, so
make those code snippets into blocks then, to reduce the scope of
those variables. Workaround for weird errors as reported by gcc 4.2.1
in the 10.6 SDK:

SalAquaPicker.cxx: In member function 'void SalAquaPicker::implInitialize()':
SalAquaPicker.cxx:134: error: jump to case label
SalAquaPicker.cxx:127: error:   crosses initialization of 'NSNumber* pExtn'
SalAquaPicker.cxx:126: error:   crosses initialization of 'NSUserDefaults* pDefaults'
SalAquaPicker.cxx:141: error: jump to case label
SalAquaPicker.cxx:127: error:   crosses initialization of 'NSNumber* pExtn'
SalAquaPicker.cxx:126: error:   crosses initialization of 'NSUserDefaults* pDefaults'

Fixes warnings 'SfxStandaloneDocumentInfoObject' declared with greater
visibility than the type of its field
'SfxStandaloneDocumentInfoObject::<anonymous>' and
'SfxStandaloneDocumentInfoObject' declared with greater visibility
than its base 'SfxDocumentInfoO\ bject'.
