PR14927: change error messages from using warn/x() to staperror()

1. Using staperror() will preface the errors with an "ERROR:" string,
   which may be colored, depending on the coloring mode.
2. The use of warn() and family are not recommended as they are provided

11 years agotoken colorizer: eschew tok_embedded etc. types
Frank Ch. Eigler [Tue, 9 Jul 2013 19:19:10 +0000 (15:19 -0400)]
token colorizer: eschew tok_embedded etc. types

When printing source context for an error, we don't really know how
many characters from the source to highlight for any given token, as
that only stores the starting column position.

The tok->content.size() is a guide, but not a perfect one, as for some
(tok_string, tok_embedded, ...), the content is processed from the
source characters (with quotation signs removed, etc.), for others,
the tok->content() can be many lines long.  That's a problem because
if we try to source_line.substr(..., long_multiline_token.length()...),
we'll get a SEGV.

So we colorize only those tokens whose type is known to be simple and
literal transcriptions of the source file, starting at
column=tok->column.
