    Fix parse failure when 4-byte character in UTF-16 BE is split across a chunk

This makes the logic in UTF16BEToUTF8() match UTF16LEToUTF8().

* encoding.c:
(UTF16LEToUTF8):
- Fix comment to describe what the code does.
(UTF16BEToUTF8):
- Fix undefined behavior which was applied to UTF16LEToUTF8() in
  2f9382033e.
- Add bounds check to while() loop which was applied to
  UTF16LEToUTF8() in be803967db.
- Do not return -2 when (in >= inend) to fix the bug.  This was
  applied to UTF16LEToUTF8() in 496a1cf592.
- Inline (<< 8) statements to match UTF16LEToUTF8().

Add the following tests and results:

  test/text-4-byte-UTF-16-BE-offset.xml
  test/text-4-byte-UTF-16-BE.xml
  test/text-4-byte-UTF-16-LE-offset.xml
  test/text-4-byte-UTF-16-LE.xml

To build on an Unixised setup:
   ./configure ; make ; make install
   if the ./configure file does not exist, run ./autogen.sh instead.
To build on Windows:
   see instructions on win32/Readme.txt

To assert build quality:
   on an Unixised setup:
      run make tests
   otherwise:
       There is 3 standalone tools runtest.c runsuite.c testapi.c, which
       should compile as part of the build or as any application would.
       Launch them from this directory to get results, runtest checks 
       the proper functioning of libxml2 main APIs while testapi does
       a full coverage check. Report failures to the list.
