Factor out sequencing related things into an independant new library: "evoral".

Anything related to the storage of events/values over a range of time lives in evoral.
This includes MidiModel (Evoral::Sequence) and automation data (AutomationList (Evoral::ControlList),
	Automatable (Evoral::ControlSet), etc).
libs/evoral synced with http://svn.drobilla.net/lad/trunk/evoral r1511.
