uml: style fixes in FP code
Tidy the code affected by the floating point fixes.
A bunch of unused stuff is gone, including two sigcontext.c files,
which turned out to be entirely unneeded.
There are the usual fixes -
whitespace and style cleanups
copyright updates
emacs formatting comments gone
include cleanups
adding severities to printks
