[Openicc] ICC meta tag in device profiles

Oyranos and KDE's kolor-manager are now able to understand device
capabilities inside ICC profiles through the meta tag. It complies with
SampleICC. I added to some ICC profiles this tag containing device
informations from libXcm. This means its basically monitor device
identification and colorimetric data originating from EDID data blocks.
These key/value pairs are as well stored inside the Oyranos DB. The
profiles are shown in kolor-manager for a given device on top of all other
assignable ICC profiles. This priorisation shall help users to first
select ICC profile which fit to a given device.
I am not shure if kolor-manager is the best place to embedd
device and driver informations into a ICC profile. As kolor-manager has
few capabilities to change driver informations. However the association of
a ICC profile to a colour device might appear intuitive and embedding this
information into a ICC profile logical.
As well shall such key/values be stripable to make place for a different
device, e.g. to correct a wrong decission.
An other place could be the oyranos-monitor command line tool. Thus the
data is embedded perhaps more explicitely.
I currently think, embedding makes most sense to administrate and remember
a association of ICC profiles with a device. So I am not shure if the meta
tag is the right thing to let end users fiddle with.
The key/values of libXcm can be formally published and explained to allow
vendors or advanced users to generate ICC profiles fitting certain devices
developing for colour management
