92e347b556 Add copyright headers to some files that lack them 
We do our best to keep copyright headers up to date, yet
git history provides better information on this subject
and is more accurate than copyright headers.

917c2ccf3a Refactor stack pointers 
Change all linux/*/arch_regs.c to provide either ARCH_SP_REG
or ARCH_SP_PEEK_ADDR.  Introduce get_stack_pointer(), rewrite
all code accessing stack pointers to use get_stack_pointer().
On some architectures stack pointers were referred to as frame pointers,
clean up this confusion.
