*To the best of my knowledge*, we now have authorization from everyone
who has significantly contributed to NASM in the past. As such,
change the license to the 2-clause BSD license.

Add copyright headers to the *.c/*.h files in the main directory. For
files where I'm sure enough that we have all the approvals, I have
given them the 2-BSD license, the others have been given the "LGPL for
now" license header. Most of them can probably be changed after
auditing.

Add new function "local_scope" to label subsystem to
return the previous non-local label for a given local label,
and invoke this funcion in eval.c to display the fully
qualified name in the "not defined" error message.
Proper use of bool and enum makes code easier to debug. Do more of
it. In particular, we really should stomp out any residual uses of
magic constants that aren't enums or, in some cases, even #defines.
