It certainly is the oddest inverter that I've ever seen, but that's what I think it is. Usually the dot is on the output, rather than the input.

Definately an inverter. The circle denotes the inverting function, where it appears isn't that important.

Moving the inverting function is an old technique to redefine gates without redefining logic.

It is indeed an inverter. The circle at the front indicates that under normal or steady state conditions its input is high, but when the section of circuit that it is part of is activated, the input goes low.
