[gjs/wip/ptomato/mozjs52: 29/37] js: Report warnings and errors with encoding

[Philip Chimento <pchimento src gnome org>]

commit 102a6a11da1024c610bfed22c225fa7fcba90310
Author: Philip Chimento <philip chimento gmail com>

    js: Report warnings and errors with encoding
    
    JS_ReportWarning() and JS_ReportError() are changed in SpiderMonkey 52 to
    specify their character encodings. Therefore, we use JS_ReportWarningUTF8()
    and JS_ReportErrorUTF8(), except in a few cases where we use the ASCII
    version because the argument is a string literal with only ASCII characters
    and no format codes.
