Start all license/copyright notice comments with /*-, per tradition
A large majority of the source files in the tree start their license
and copyright statements in a comment that begins with /*-.  Document
this tradition.  A strict adherence to this rule will help resellers
that wish to publish all copyright notices, generated automatically
from the tree.  There are too many variant licenses to do it purely
by more complicated pattern matching.

These appear to be unused in our tree, so remove them.
Rework the optimization for spinlocks on UP to be slightly less drastic and
turn it back on.  Specifically, the actual changes are now less intrusive
in that the _get_spin_lock() and _rel_spin_lock() macros now have their
contents changed for UP vs SMP kernels which centralizes the changes.
Also, UP kernels do not use _mtx_lock_spin() and no longer include it.  The
UP versions of the spin lock functions do not use any atomic operations,
but simple compares and stores which allow mtx_owned() to still work for
spin locks while removing the overhead of atomic operations.

- Move the function prototypes for kern_setrlimit() and kern_wait() to
  sys/syscallsubr.h where all the other kern_foo() prototypes live.

Style: new-speak functions, remove pointless "return".
Align if else if properly
Typo.
