[Libdlo] libdlo dynamic modeset

The libdlo git tree also now has code to do a dynamic modeset directly
from VESA video timings to the DL video registers.  Through the API,
this path is hit whenever a mode is set with NULL parameters or zero
width -- and in that case, it pulls the VESA video timings from the
preferred detailed timings in the EDID, and directly sets that mode.
The library's tests use this new path by default.

Note that some combinations of DisplayLink devices and monitors may
not yet working on this new path -- any reports of problems are
welcome.

And the mode blobs are still in there for the VESA standard modes and
still used when a specific mode is requested -- but if we can get
all/enough combinations to work without the tables, those also will be
simplified to just start from vesa timings.
