UTF8 strchug/chomp/strip

["ANDREW PAPROCKI, BLOOMBERG/ 731 LEXIN" <apaprocki bloomberg net>]

I noticed that glib doesn't contain g_utf8_strchug, g_utf8_strchomp, g_utf8_strstrip (macro), which would be UTF8 safe versions of the functions in gstrfuncs.c.

Conveniently, these functions already exists in file-roller, which I found here:

Can these be pulled down into gutf8.c / gunicode.h?

Thanks,
