Add a method to fetch descriptor options. Since options are proto
messages (e.g., google.protobuf.FieldOptions), and proto message
packages depend on the protoreflect package, returning the actual option
type would cause a dependency cycle. Instead, we return an interface
value which can be type asserted to the appropriate concrete type.
Add options support to the prototype package.
Some of the prototype constructors included fields (such as
Field.IsPacked) which represent information from the options
(such as google.protobuf.FieldOptions.packed). To avoid confusion about
the canonical source of information, drop these fields in favor of the
options.
Drop the unimplemented Descriptor.DescriptorOptionsProto.

This change was created by running:
git ls-files | xargs sed -i "s|google.golang.org/proto|github.com/golang/protobuf/v2|g"
This change is *not* an endorsement of "github.com/golang/protobuf/v2" as the
final import path when the v2 API is eventually released as stable.
We continue to reserve the right to make breaking changes as we see fit.
This change enables us to host the v2 API on a repository that is go-gettable
(since go.googlesource.com is not a known host by the "go get" tool;
and google.golang.org/proto was just a stub URL that is not currently served).
Thus, we can start work on a forked version of the v1 API that explores
what it would take to implement v1 in terms of v2 in a backwards compatible way.

Minor changes:
* Use spaces instead of tabs in help printout since each system may have
a different tab width.
* Reduce repetition for field flags.
* Print to stdout instead of stderr for flag usages as is customary for
most other Unix command line tools.

The pbdump binary is an internal-only command line tool that is similar
to the hexdump tool in Linux, but is tailored towards the protocol buffer
wire format. This tool is not necessary for the new API, but is very useful
for debugging the wire format.
