The printf library I have been using, while useful, has way more than I need in it, and had comparably huge stack space requirements. This change adds a new util::format() which is a replacement for snprintf, but with only the features used by kernel logging. The logger has been changed to use it, as well as the few instances of snprintf in the interrupt handling code before calling kassert. Also part of this change: the logger's (now vestigial) immediate output handling code is removed, as well as the "sequence" field on log message headers.
