      New rtl::isUnicodeScalarValue, rtl::isSurrogate · 3f0fba00
      Stephan Bergmann yazdı 
      There are apparently various places that want to check for a Unicode scalar
value rather than for a Unicode code point.  Changed those uses of
rtl::isUnicodeCodePoint where that was obvious.  (For changing
svtools/source/svrtf/svparser.cxx see 8e0fb74d
"Revert 'svtools: HTML import: don't put lone surrogates in OUString'".)  Other
uses of rtl::isUnicodeCodePoint might also want to use rtl::isUnicodeScalarValue
instead.

As a side effect, this change also introduces rtl::isSurrogate, which is useful
in a few places as well.

      stoc: deadlock osl::Mutex::getGlobalMutex() vs getImplHelperInitMutex() · 7936368f
      Michael Stahl yazdı 
      As found in a clang/ASAN build running UITest_writer_demo.

cppu::getTypeEntries locks getImplHelperInitMutex().

Let's try to replace the usage of getGlobalMutex() in proxyfac_create()
with a new static Mutex that is only used in that function.
