467795f467 Fix Latency Measurement without device re-start 
This handles a case when the engine was started normally
(not for latency measurement), and measurement is performed later.
This resulted in a duplicate backend start

1c8b6e1b42 Initialize uninitialized variables 
If a session with a feedback loop is loaded, Graph::rechain()
is never called, and _n_terminal_nodes[] remains unset.

d52cf0f739 Tweak graph display, check direct sends 
->feeds() follows connections "track -> master -> monitor"
(to detect feedback). Use direct_feeds_according_to_reality()
to correctly show sends-only.

45f1220aa5 Fix deadlock when removing routes (initialization issues) 
_setup_chain needs to point to the unused graph-chain, and not
_current_chain. Otherwise Graph::clear_other_chain() waits forever.

b7369f421f Re-work process-graph to use lock-free queues 
This removes the trigger_mutex which was used for exclusive access
of the work-queue for concurrent processing.

249640267c Remove global declick API 
De-click will be per disk-reader, latency compensated and buffer-size
independent. Cue-monitoring should not be affected by de-click.

a2897ecef6 Fairly major change to the way in which crossfades are handled; 
they are now done with region fades, rather than separate objects.
After this commit, Ardour will try to convert your session files
to the new crossfade format, but will make a backup in your
session folder first.

If you have works in progress using Ardour 3 it is
***STRONGLY RECOMMENDED*** that you back up session files before
updating to this commit.

e317386c5c For now, only use the multi-threaded process code if we are 
using >1 processor for DSP; this involves making the DSP
use setting only take effect on a restart of Ardour.

69c88d165d Alert the user if a connection is made which causes 
feedback, and preserve the route graph in the state
that it was in before the feedback was introduced. The
intent being to simplify the code, reduce the number of
areas of code which must consider feedback, and fix a
few bugs.
