When making context managers in Python, the yield statement has to be wrapped in a try/finally clause in order to properly clean up after exceptions happen.
- Fix the syntax to open mboard-regs UIO objects, and change the open()
and close() functions to be private.
- We were calling open() twice in every context manager line- once
manually, and once in __enter__. This commit corrects those usages, and
allows the context manager to fully manage the opening and closing of
UIO objects.
Because the detection of valid Ethernet devices happens across multiple
calls in a non-atomic fashion, we cannot assume that a device passed to
net.get_iface_info() actually has a valid IP address, so we don't make
that assumption.
UIO objects now count references on open and close calls. This should
prevent problems with nested function calls that open/close the same
UIO object.
References counts are not atomic -- this is intended for nesting with
statements within the same thread context.

GPIOBank is the new class, n310.FrontpanelGPIO and BackpanelGPIO now
derive from that.
Other minor changes:
- Renamed classes to FrontpanelGPIO and BackpanelGPIO in accordance
with coding guidelines
- Moved MboardRegsControl before n310 class for consistent code layout
Refactoring to use the C++-based UIO objects. The Liberio and Ethernet
objects now open the UIO before using it, and close it once done.
