Strbuf API extensions and fixes.
* Add strbuf_rtrim to remove trailing spaces. * Add strbuf_insert to insert data at a given position. * Off-by one fix in strbuf_addf: strbuf_avail() does not counts the final \0 so the overflow test for snprintf is the strict comparison. This is not critical as the growth mechanism chosen will always allocate _more_ memory than asked, so the second test will not fail. It's some kind of miracle though. * Add size extension hints for strbuf_init and strbuf_read. If 0, default applies, else: + initial buffer has the given size for strbuf_init. + first growth checks it has at least this size rather than the default 8192.
