score: Make EDF the default SMP scheduler
The EDF SMP scheduler supports simple thread processor affinities
(see #3059) with a small run-time overhead. The current default SMP
scheduler lacks support for thread processor affinities at all. The EDF
SMP scheduler offers a good feature set for most applications. So, use
it by default. Run-time libraries like libgomp, MTAPI, work stealing
schedulers, language interpreters (e.g. Erlang virtual machine),
maintainence of per-processor data (e.g. Universal Memory Allocator
(UMA)), etc. use a one-to-one thread processor affinity for example.
Update #3063.
