At some point in time, protoc-gen-go actually emitted an XXX_OneofFuncs
with a different signature. Adjust the logic for handling XXX_OneofFuncs
to not assume that the return arguments are in a specific order.

Add support for an ExtensionDesc with only Field populated as returned by
protoV1.ExtensionDescs. Rather than panicking when TypeDescriptor is called,
return a placeholder that preserves the name and/or number.

Previously, when aberrantLoadMessageDesc returned it was guaranteed
to have initialized the current message through the use of the done signal.
However, this does not guarantee that the descriptor for a cylic reference
has also finished initialization.
Rather than add more complicated logic to wait until all cyclic references
have finished initializing, just add a global lock for the entire
aberrantLoadMessageDesc function.
This slows down performance, but is easier to reason about.

The aberrant support logic only has access to the Go type
information, and not a concrete value. However, the XXX_MessageName
method exists on some hacky dynamic proto implementations where
it is only valid to call on a concrete value, not just newly created
instance of the given type.
However, from the perspective of the support logic, it is impossible
to distinguish between dynamic messages and hand-crafted custom messages.
Thus, just drop support for XXX_MessageName. We won't get the full name
of the message right, but oh well, what can we do.

Aberrant messages are hand-crafted messages that happen to work because
they use the same struct tags that generated code emits.
This happens to work in v1, but is unspecified behavior and entirely outside
the compatibility promise.
Support for this was added early on in the history of the v2 implementation,
but entirely untested. It was removed in CL/182360 to reduce the
technical debt of the legacy implementation. Unfortunately, sufficient number
of targets do rely on this aberrant support, so it is being added back.
The logic being added is essentially the same thing as the previous logic,
but ported to use internal/filedesc instead of the now deleted
internal/prototype package.
