Add muen scheduling info as timer source

This is a very low precision clock. We just take the start of the cur-
rent scheduling minor frame as the minimum, yet elapsed moment and the
end of the frame as the maximum, yet reached moment in time. As a
result, every timer based delay will wait at least for the next minor
frame.

For the build, `musinfo.ads` and `muschedinfo.ads` from the Muen
project are required. One should point the `muen-common-path` variable
to the `common` subdir of the Muen source distribution.
