Generated .pb.go files are created by generate.bash using Go 1.18,

Centralize the MessageSet extension resolution logic in the registry.
This avoids needless replication of this exact logic in multiple places
(for JSON and text) and elsewhere.

When combining multiple message fields in a MessageSet item (a case
which should never happen in practice), unmarshal could modify the input
data. Fix it to not do so. Add a general check to ensure that unmarshal
operations don't modify the input.

For historical reasons, MessageSets items are allowed to have field
numbers outside the usual valid range. Detect the case where the field
number cannot fit in an int32 and report an error. Also check for
a field number of 0 (always invalid).
Handle the case where a MessageSet item includes an unknown field.
We have no place to put the contents of the field, so drop it. This is,
I believe, consistent with other implementations.

Add a sentinel proto.Error error which matches all errors returned by
packages in this module.
Document that protoregistry.NotFound is an exact sentinel value for
performance reasons.
Add a Wrap function to the internal/errors package and use it to wrap
errors from outside sources (resolvers). Wrapped errors match
proto.Error.

In the v1 implementation, unknown MessageSet items are stored in a
message's unknown fields section in non-MessageSet format. For example,
consider a MessageSet containing an item with type_id T and value V.
If the type_id is not resolvable, the item will be placed in the unknown
fields as a bytes-valued field with number T and contents V. This
conversion is then reversed when marshaling a MessageSet containing
unknown fields.
Preserve this behavior in v2.
One consequence of this change is that actual unknown fields in a
MessageSet (any field other than 1) are now discarded. This matches
the previous behavior.

Descriptor methods generally return a Descriptor with no Go type
information. ExtensionType's Descriptor is an exception, returning an
ExtensionTypeDescriptor containing both the proto descriptor and a
reference back to the ExtensionType. The pure descriptor is accessed
by xt.Descriptor().Descriptor().
Rename ExtensionType's Descriptor method to TypeDescriptor to make it
clear that it behaves a bit differently.
Change 1/2: Add the TypeDescriptor method and deprecate Descriptor.

Change protoiface.ExtensionDescV1 to implement protoreflect.ExtensionType.
ExtensionDescV1's Name field conflicts with the Descriptor Name method,
so change the protoreflect.{Message,Enum,Extension}Type types to no
longer implement the corresponding Descriptor interface. This also leads
to a clearer distinction between the two types.
Introduce a protoreflect.ExtensionTypeDescriptor type which bridges
between ExtensionType and ExtensionDescriptor.
Add extension accessor functions to the proto package:
proto.{Has,Clear,Get,Set}Extension. These functions take a
protoreflect.ExtensionType parameter, which allows writing the
same function call using either the old or new API:
proto.GetExtension(message, somepb.E_ExtensionFoo)
