[PATCH 1/4] Remove copyinfrom() and copyinstrfrom().

[Sebastian Huber]

From: John Baldwin <jhb at FreeBSD.org>

These functions were added in 2001 and are currently unused.
copyinfrom() looks to have never been used.  copyinstrfrom() was used
for two weeks before the code was refactored to remove it's sole use.
