8d30bbeede all: remove dependency on proto v1
This does not remove all dependencies,
but all of the cases where it can now be implemented in terms of v2.

8c86fc5e7d all: remove non-fatal UTF-8 validation errors (and non-fatal in general)
Immediately abort (un)marshal operations when encountering invalid UTF-8
data in proto3 strings. No other proto implementation supports non-UTF-8
data in proto3 strings (and many reject it in proto2 strings as well).
Producing invalid output is an interoperability threat (other
implementations won't be able to read it).

The case where existing string data is found to contain non-UTF8 data is
better handled by changing the field to the `bytes` type, which (aside
from UTF-8 validation) is wire-compatible with `string`.

Remove the errors.NonFatal type, since there are no remaining cases
where it is needed. "Non-fatal" errors which produce results and a
non-nil error are problematic because they compose poorly; the better
approach is to take an option like AllowPartial indicating which
conditions to check for.

378c1329de reflect/protoreflect: add alternative message reflection API
Added API:
	Message.Len
	Message.Range
	Message.Has
	Message.Clear
	Message.Get
	Message.Set
	Message.Mutable
	Message.NewMessage
	Message.WhichOneof
	Message.GetUnknown
	Message.SetUnknown

Deprecated API (to be removed in subsequent CL):
	Message.KnownFields
	Message.UnknownFields

The primary difference with the new API is that the top-level
Message methods are keyed by FieldDescriptor rather than FieldNumber
with the following semantics:
* For known fields, the FieldDescriptor must exactly match the
field descriptor known by the message.
* For extension fields, the FieldDescriptor must implement ExtensionType,
where ContainingMessage.FullName matches the message name, and
the field number is within the message's extension range.
When setting an extension field, it automatically stores
the extension type information.
* Extension fields are always considered nullable,
implying that repeated extension fields are nullable.
That is, you can distinguish between a unpopulated list and an empty list.
* Message.Get always returns a valid Value even if unpopulated.
The behavior is already well-defined for scalars, but for unpopulated
composite types, it now returns an empty read-only version of it.

c37adefdac internal/impl: add fast-path marshal implementation
This is a port of the v1 table marshaler, with some substantial
cleanup and refactoring.

Benchstat results from the protobuf reference benchmark data comparing the
v1 package with v2, with AllowPartial:true set for the new package. This
is not an apples-to-apples comparison, since v1 doesn't have a way to
disable required field checks.  Required field checks in v2 package
currently go through reflection, which performs terribly; my initial
experimentation indicates that fast-path required field checks will
not add a large amount of cost; these results are incomplete but not
wholly inaccurate.

e6f060fdac proto: add Equal
Add support for basic equality comparison of messages.

Messages are equal if they have the same type and marshal to the
same bytes with deterministic serialization, with some exceptions:

 - Messages with different registered extensions are unequal.
 - NaN is not equal to itself.

Unlike the v1 Equal, a nil message is equal to an empty message of
the same type.
