2020-04-28	Support the SMT-LIB Unicode string standard by default (#4378)	Andrew Reynolds
	This PR merges --lang=smt2.6.1 and --lang=smt2.6 (default). It makes it so that 2.6 always expects the syntax of the string standard http://smtlib.cs.uiowa.edu/theories-UnicodeStrings.shtml. I've updated the regressions so that the 2.6 benchmarks are now compliant with the standard. Some of the <=2.5 benchmarks I've updated to 2.6. Others I have left for now, in particular the ones that rely on special characters or ad-hoc escape sequences. The old formats will be supported in the release but removed shortly afterwards. This PR is a prerequisite for the release, but not necessarily SMT-COMP (which will use --lang=smt2.6.1 if needed). Notice that we still do not have parsing support for str.replace_re or str.replace_re_all. This is required to be fully compliant.
2020-02-21	Simple changes towards unicode string standard (#3791)	Andrew Reynolds
	This updates --lang=smt2.6.1 with the minor syntactic differences from the current syntax and the standard here: http://smtlib.cs.uiowa.edu/theories-UnicodeStrings.shtml. The next steps will be to address the more invasive changes required to support the standard.
