Add EDID framework. (No documentation as yet.)
This allows one to query monitors (or use BIOS EDID data) and learn their default modes, etc. To use this, pass an EDID data block edid_parse(), and get back nicely parsed data, including precalculated modes using GTF, etc. The result can be printed using edid_print(). Also, if you want to use GTF to generate modes without EDID, you can use the vesagtf pseudo-device. vesagtf.c can also be compiled as a standalone program to generate XFree86 modelines.
