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.

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.

8fa0e6c914 Add shims for old NetworkTable interface.

6f940bcaaf Add immediate_notify and is_new to entry listener. 
On the callback function, is_new indicates the value is newly added.

On adding a callback function, immediate_notify indicates the callback
should be called once (with is_new=true) for each matching entry that
already exists.
