At some point arm moved to a unified syntax for arm and thumb instructions.
While binutils supports both "unified" and "divided" syntax (defaulting
to divided) the integrated assembler in clang only supports unified names
so switch some files to unified syntax. Similiar changes were made in
bitrig and freebsd. No difference in objdump -d output.

Make bcopy() involve memmove(), not memcpy().
Do not bogusly return NULL if dst == src (spotted by tedu@)

First pass at removing clauses 3 and 4 from NetBSD licenses.

Not sure what's more surprising: how long it took for NetBSD to

First pass at removing clauses 3 and 4 from NetBSD licenses.

Not sure what's more surprising: how long it took for NetBSD to
catch up to the rest of the BSDs (including UCB), or the amount of
code that NetBSD has claimed for itself without attributing to the
actual authors.
