e9073a3cc0 Implement notifiers. 
The notifier thread is lazily started when the first notifier is added.
This avoids the extra thread/processing overhead when notifiers are not used.

6703968f73 Dispatcher: Fix shutdown order race. 
We need to wait until after the dispatch and client/server threads have
been stopped before closing connections, as these threads can add connections.

b5274a495e Dispatcher: Don't call Storage::GetInstance() internally. 
This makes it difficult to test.  Instead, store reference as member variable,
and populate it at constuction (with an alternate constructor available for
test purposes).

f0e3bb5164 artf4165: D term of PID controller now uses change in input instead of change in error 
This avoids large additions introduced by the D term when a step change occurs in the setpoint. Otherwise, the changes return the same values. Let error = setpoint - input and prevError = prevSetpoint - prevInput. If the D term is calculated via error - prevError, then:

error - prevError = (setpoint - input) - (prevSetpoint - prevInput)

If we ignore the setpoint changing, then we get:

error - prevError = (setpoint - input) - (setpoint - prevInput)
                  = prevInput - input

a0d30ffef1 Storage: Use StringMap instead of ConcurrentQueue for updates. 
Updates are merged or themselves updated as user code changes.  This avoids
the need for the dispatcher to do this and also avoids the need for disabling
updates when the dispatcher isn't running, because there's no risk of memory
usage piling up.

fb1b82e239 StorageEntry: Also store copy of name here. 
This wastes a bit of space but is necessary for assign message generation.

18659257d3 Storage: Make setters globally atomic. 
Previously, setters were locally but not globally atomic because they
used GetEntry() (globally atomic) in conjunction with locally atomic
gets/sets to the StorageEntry.  To support synchronizing network handshakes
they need to be globally atomic.

GetEntry() has been removed due to this issue, so a helper was added to
StorageTest instead.
