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
