Whitespace cleanup: remove trailing whitespace

Remove all trailing whitespace from the following list of files: *.cpp *.h *.conf *.qdoc *.pro *.pri *.mm *.rc *.pl *.qps *.xpm *.txt *README excluding 3rdparty, test-data and auto generated code. Note A): the only non 3rdparty c++-files that still have trailing whitespace after this change are: * src/corelib/codecs/cp949codetbl_p.h * src/corelib/codecs/qjpunicode.cpp * src/corelib/codecs/qbig5codec.cpp * src/corelib/xml/qxmlstream_p.h * src/tools/qdoc/qmlparser/qqmljsgrammar.cpp * src/tools/uic/ui4.cpp * tests/auto/other/qtokenautomaton/tokenizers/* * tests/benchmarks/corelib/tools/qstring/data.cpp * util/lexgen/tokenizer.cpp Note B): in about 30 files some overlapping 'leading tab' and 'TAB character in non-leading whitespace' issues have been fixed to make the sanity bot happy. Plus some general ws-fixes here and there as asked for during review. Change-Id: Ia713113c34d82442d6ce4d93d8b1cf545075d11d Reviewed-by: Oswald Buddenhagen <oswald.buddenhagen@digia.com>
