Kill some changelogs which simply take up space and serve almost no
purpose as git history has it all and detailed. Also, remove unneeded
function definitions from traps.c

Those were leftovers of the x86 merge, see

  081f75bbdc86 ("traps: x86: make traps_32.c and traps_64.c equal")

for example and are not needed now.

It is useless and git history has it all detailed anyway. Update
copyright while at it.
