The Format function and MarshalOptions.Format method are helper
functions for directly obtaining the formatted string for a message
without having to deal with errors or convert a []byte to string.
It is only intended for human consumption (e.g., debugging or logging).
We also add a MarshalOptions.Multiline option to specify that the output
should use some default indentation in a multiline output.
This assists in the v1 to v2 migration where:
protoV1.CompactTextString(m) => prototext.MarshalOptions{}.Format(m)
protoV1.MarshalTextString(m) => prototext.Format(m)
At Google, there are approximately 10x more usages of MarshalTextString than
CompactTextString, so it makes sense that the top-level Format function
does multiline expansion by default.
Fixes#850

Ensure that EnumOf, EnumDescriptorOf, EnumTypeOf, ProtoMessageV1Of,
ProtoMessageV2Of, MessageOf, MessageDescriptorOf, and MessageTypeOf
all return nil if passed a nil interface.
This parallels the behavior of reflect.TypeOf or reflect.ValueOf,
which return nil or an invalid value rather than panicking.

The Message.String method is intended for debugging,
so outputting <nil> for typed nil messages actually has use.
This matches the current behavior of Message.String

This changes text marshaling to avoid unknown fields by default
and instead adds an option so that unknown fields be emitted.
This ensures that the default marshal/unknown can round-trip.

This CL:
* Make the meaning of impl/ExtensionInfo.goType consistent. Before,
it was sometimes a T and other times a []T depending on the current
state of initialization. Change it so that it is the constructor's
responsibility to pass in a []T if it is repeated.
* Make internal/filetype responsible for constructing a []T for
repeated extension fields.
* Makes filedesc/Extension.Cardinality one of the eagerly initialized
pieces of information since it is useful to internal/filetype.
* Unify ExtensionInfo.desc and ExtensionInfo.tdesc.ExtensionField,
which held the same information.
* Remove the internal implementation for impl.X.ExtensionDescFromType
since we are dropping support for this from v1.

Note that the following continue to panic:

MessageDescriptorOf(nil)
MessageTypeOf(nil)
It may be reasonable for them to also return nil in the future.

Change protoV1.ExtensionDesc to directly implement ExtensionType
rather than delegating to one.
Unify the previous types protoiface.ExtensionDescV1 and
filetype.Extension in impl.ExtensionInfo. The protoV1.ExtensionDesc
type becomes an alias to ExtensionInfo.
This gives us:
- Just one implementation of ExtensionType.
- Generated foopb.E_Ext vars are canonical ExtensionTypes.
- Generated foopb.E_Ext vars are also v1.ExtensionDescs for backwards
compatibility.
- Conversion between legacy and modern representations happens
transparently when lazily initializing an ExtensionInfo.
Overall, a simplification for users of generated code, since they can
mostly ignore the ExtensionDesc/ExtentionType distinction and use the
same value in either the old or new API.

Remove the remaining uses of the prototype package.
The most significant change is to impl.MessageInfo, which now directly
implements the MessageType interface. This involves two notable changes
to exported fields of MessageInfo:
- PBType is now Desc.
- GoType is now GoReflectType. (Name changed to avoid a conflict with
the GoType method of the MessageType interface.)

The internal/legacy package was originally separated out from internal/impl
to avoid a cyclic dependency on descriptor proto. However, the dependency
that legacy has on descriptor has long been dropped such that we can
now merge the two packages together again.
All legacy related logic are in a file with a legacy prefix.
