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. Signed-off-by: H. Peter Anvin <hpa@zytor.com>
