Branch:	slaclab/ESROGUE-497-2
Jira:	https://jira.slac.stanford.edu/issues/ESROGUE-497-2

This bugs make a Queue object, and therefore a Rogue Fifo object, to hold one more data point than the maximum requested.

Same changes as #775 but rogue version v4.

Fifo: Expose status information to python (for version v4)

Author:	Ryan Herbst [email protected]

Pull:	#778 (123 additions, 15 deletions, 4 files changed)
Branch:	slaclab/ESROGUE-498-2
Issues:	#778
Jira:	https://jira.slac.stanford.edu/issues/ESROGUE-498-2
Labels:	enhancement

Notes:

This PR exposes some useful status information from a Fifo device to python. The information exposed is:

• The maximum depth of the fifo,
• Current number of elements in the fifo, and
• The number of dropped frames, with a clear command.

Additionally, a python wrapper for the C++ class was added.

Finally, a couple of optimization were added as well:

• Use member initializer list for the Fifo C++ class, which offer a better performance when creating the objects, and
• Add a missing delete to match the new operator, in order to avoid leaking the memory.

Same changes as #776 but for rogue version v4.
