Allow decoding nvidia CPERs

There are cases where satmc might not be able to buffer the full CPER
message. In those cases, it is advantageous if the decoder continues as
far as it can.

This commit moves a range check in nvidia cpers such that if there is a
buffer error, the CPER registers are still iterated until we hit the
buffer error, then filled in with null after the buffer error. This
makes it more clear what the issue is, and decodes more of the output.

Implement common logging function

When used as a library, it's desirable to be able to suppress logging,
or pipe logging through a different path. This commit changes behavior
such that logging is disabled by default, and introduces 2 new methods,
cper_set_log_stdio and cper_set_log_custom.

These allow library integrators to specify their logging mode. In
practice, this also allows fuzzing to run faster by not printing errors
to the log.

Unflatten edk includes

Installing the edk headers into a folder requires us to do odd things
with imports, and either include headers with "..", or otherwise get the
include directories lined up.

Move the contents of edk/*.c/h up a level, and just simplify the include
structure. This is done to fix the immediate change of the prior patch
and make this build again. Happy to discuss other options.

```

Using `strncpy` on its own is unsafe because a string too long will
end up in the destination buffer without NUL termination. Adjust
the strncpy to be one shorter than the buffer and force the trailing
byte to be a NUL.

Repeat this pattern for all `strncpy` calls.
