[RFC PATCH] sim: switch Cygnus Solutions copyrights to FSF

[RFC PATCH] sim: switch Cygnus Solutions copyrights to FSF

[Mike Frysinger via Gdb-patches]

This was done for the vast majority of files in the sim tree, but looks
like these few were missed.  While Cygnus Solutions doesn't exist today,
it merged with RedHat who has FSF assignment in place.

I would ask the copyright clerk at the FSF (copyright-clerk@fsf.org)
about that. Intuitively, even though Cygnus has been merged into
RedHat, and RedHat has a copyright assignment on file for *past*
and future changes, I don't know that it means *any* past changes
contributed by an entity which became part of RH after the change
was contributed can see its copyright be re-assigned. I'm wondering
if someone at RedHat must give permission or rather express the
desire to assign this code's copyright to the FSF?

thanks, i'll reach out to the FSF.  these old copyrights are annoying
because it's easy to miss when refactoring or writing new code when the
rest of the code base is FSF.
