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.

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.

This warns when implicit conversions may alter a value. It's easy
to miss implicit conversions from signed to unsigned, from real to
integer, or to smaller types. This warning forces such conversions
to be explicit.

Enable a few extra warning options, including -Walloca because it's
error-prone. Enable -Wdeclaration-after-statement to enforce the code
style. Disable -Wunused-parameter and -Wmissing-field-initializers
because these are pointless and don't catch bugs.
Inspired from the Weston and wlroots options.
