Robert Watson 05e830f1e7 Rewrite Biba and MLS label externalization code to use sbufs instead ... of C strings internally; C strings require a lot of return value checking that (a) takes a lot of space, and (b) is difficult to get right. Prior to the advent of compartment support, modeling APIs for helper functions on snprintf worked fine; with the additional complexity, the sbuf_printf() API makes a lot more sense. While doing this, break out the printing of sequential compartment lists into a helper function, mac_{biba,mls}_compartment_to_string(). This permits the main body of mac_{biba,mls}_element_to_string() to be concerned only with identifying sequential ranges rather than rendering. At a less disruptive moment, we'll push the move from snprintf()-like interface to sbuf()-like interface up into the MAC Framework layer.
