libpayload: Add a new "die" function to fatally signal programming errors.

If a programming error is detected, die can be used to print a message and
    stop execution similar to failing an assert. There's also a "die_if" function
    which is conditional.

die functions, like asserts, should be used to trap programming errors and not
    when the hardware does something wrong. If all code was written perfectly, no
    die function would ever be called. In other words, it would be appropriate to
    use die if a function was called with a value that was out of bounds or if
    malloc failed. It wouldn't be appropriate if an external device doesn't
    respond.

In the future, the die family of functions might print a stack trace or show
    other debugging info.

libpayload: Fix the license in some files which were accidentally made GPL.

Some files were accidentally made GPL when they were added to libpayload. This
    change changes them over to a BSD license to be in line with the intended
    license of libpayload.
