c01982bdb1 Add skeleton for high-level API
This exposes a new di_info opaque struct from which high-level
information will be able to be queried by the user. A new
di_info_parse_edid function creates a di_info from an EDID blob.

ad1e3f4167 Add very basic EDID functions
Introduce an opaque struct di_edid to host EDID structures. Add
a function to create a di_edid (with basic size, header and
checksum validation). Add functions to fetch the EDID version and
revision.

This doesn't do much, but hopefully can be used as a fundation.
