Adapt OSD in plugin lib to be greylib compatible.

Browse source 
Requires addition of viewports and alternate framebuffers to greylib
which are essentially similar to the core implementation except that
the framebuffer can be any size and relationship to a viewport. Drawing
is always fully clipped to the intersecting area.

Adapt oscilloscope.c to the API change. FFT will use the new features
(later update).

Get rid of silly and wrong lcd_bmp_part use in OSD. Remove it from
plugin API (must be made incompatible now).
