Subject: Add LLStringUtil::getTokens() overload handling quoted substrings. We
 didn't have any tokenizer suitable for scanning something like a bash command
 line. We do have a couple hacks, e.g. LLExternalEditor::tokenize() and
 LLCommandLineParser::parseCommandLineString(). Both try to work around
 boost::tokenizer limitations; but existing boost::tokenizer support just
 doesn't address this case. Neither of the above is available as a general
 scanner anyway, and parseCommandLineString() fails outright when passed "".
 New getTokens() also distinguishes between "drop delimiters" (e.g. space,
 return, newline) to be discarded from the token stream, versus "keep
 delimiters" (e.g. "+-*/") to be returned as tokens in their own right.
 There's an overload that honors escapes and a more efficient one that
 doesn't; each has a convenience overload that returns the scanned string
 vector rather than requiring a separate declaration. Tweak and comment older
 getTokens() implementation. Add unit tests for both old and new getTokens()
 implementations. Break out StringVec and std::ostream << StringVec from
 indra/llcommon/tests/listener.h to StringVec.h: that's coming in handy for a
 number of different TUT test sources.
