edid: Change static variables to auto variables.

To support parsing multiple EDID blobs, the static "decode results" flags should
be changed to auto variables inside decode_edid.

This is done by packaging static variables into a structure inside decode_edid.
We also revised some functions (manufacturer_name, do_checksum) to avoid
accessing global variables directly. Extension (and detail block) parsing may
need to access and return all parsed context so we pass the whole structure to
it.
