Notable changes include
- removal of unbounded string functions
- automatic support for nmea(4) timedelta sensors
- lots of driver updates
- profiled and cleaned up hot spots
- runtime reliability fixes
Lots of good advice from steven and naddy, ok naddy@
the FULLPKGPATH, thus providing changes to packing-lists which shouldn't
happen, and making update more difficult.
Accordingly, bump all pkgnames with PSEUDO_FLAVORS, and provide an
update @pkgpath for the bug for most of them (left out the ones with 3
or 4 pseudo flavors for space constraints...)
