Overview of changes:
* Add an option that specifies whether to replace unresolvable references
with a placeholder instead of producing an error. Since the prior behavior
produced placeholders (not always), we default to that behavior for now,
but will enable strict resolving in a future CL.
* The option is not yet exported because there is concern about what the
public API should look like. This will be exposed in a future CL.
* Unlike before, we now permit placeholders for unresolvable enum values.
* We implement relative name resolution logic.
* We handle the case where the type is unknown, but type_name is specified.
In such a case, we populate both FieldDescriptor.{Enum,Message} and leave
the FieldDescriptor.Kind with the zero value. If the type_name happened
to resolve, we use that to determine the type.
* If a placeholder is used to represent a relative name,
the FullName reports an invalid full name with a "*." prefix.

The internal/fileinit package is split apart into two packages:
* internal/filedesc constructs descriptors from the raw proto.
It is very similar to the previous internal/fileinit package.
* internal/filetype wraps descriptors with Go type information
Overview:
* The internal/fileinit package will be deleted in a future CL.
It is kept around since the v1 repo currently depends on it.
* The internal/prototype package is deleted. All former usages of it
are now using internal/filedesc instead. Most significantly,
the reflect/protodesc package was almost entirely re-written.
* The internal/impl package drops support for messages that do not
have a Descriptor method (pre-2016). This removes a significant amount
of technical debt.
filedesc.Builder to parse raw descriptors.
* The internal/encoding/defval package now handles enum values by name.

Temporarily remove go.mod, since we can't generate an accurate one until
the corresponding v1 change is submitted.

Logic for serializing the default value in textual form exists in
multiple places in trivially similar forms. Centralize that logic.
