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.

When libpayload header files are included in the payload itself, it's possible
that the payloads config settings will conflict with the ones in libpayload.
It's also possible for the libpayload config settings to conflict with the
payloads. To avoid that, the libpayload config settings have _LP_ (for
libpayload) added to them. The symbols themselves as defined in the Config.in files
are still the same, but the prefix added to them is now CONFIG_LP_ instead of just
CONFIG_.

The hexdump function was added to libpayload recently, but its source file was
never added to the Makefile so it wasn't compiled or linked in.
