This is used as the minimum refresh rate in the variable refresh rate
range.
This value is expected to be found in the DisplayPort and eDP EDID of
every monitor that supports variable refresh rate.
It is also found in the HDMI EDID of some monitors that support
variable (FreeSync), but most likely not all of them. The rest require
parsing the AMD vendor extension which libdisplay-info doesn't
support.
No fallback is implemented for cases where libdisplay-info support is
disabled.

They are float in libdisplay-info and our own EDID parsing also returns
a float but when then converted both to an integer. Especially the min
luminance can be <1.
We also don't need a variable for indicating presence of a CTA Static
Metadata block. The values are all zero if it is absent.

Hides libdisplay-info under a build time default-off flag,
provides provision to parse essential edid parameters with
APIs provided by libdisplay-info. This implementaion increases
readibility, avoids code duplication and decreases complexity
of edid parsing.

The EDID code is copy from elsewhere, without adapting to conventions
regarding e.g. API and types. Clean this up a bit, as EDID information
will be kept around longer when possible, to be used e.g. by color
management.
