Support C11 Unicode string literals and character constants (#452)
* Support C11 Unicode string literals and character constants
* Add tests for C11 string literals and character constants
* Better error message for ill-formed universal character names
E.g. \u followed by fewer than 4 hex digits, or \U followed by fewer than 8 hex digits.
* Add new warning `invalid-utf8` for byte sequences that are not valid UTF8.
The warning is activated but not fatal by default.
* Warn on uses of C11 Unicode character constants and string literals
This uses the `c11-extensions` warning, which is off by default.
* Support preprocessing option -finput-charset= for GNU toolchains
