Objective C Second Alpha Drop

- Style fixups in the code.
- map<> serialization fixes and more tests.
- Autocreation of map<> fields (to match repeated fields).
- @@protoc_insertion_point(global_scope|imports).
- Fixup proto2 syntax extension support.
- Move all startup code to +initialize so it happen on class usage and not app startup.
- Have generated headers use forward declarations and move imports into generated code, reduces what is need at compile time to speed up compiled and avoid pointless rippling of rebuilds.

+// `Any` contains an arbitrary serialized message along with a URL
+// that describes the type of the serialized message.
+//
+// The proto runtimes and/or compiler will eventually
+//  provide utilities to pack/unpack Any values (projected Q1/15).
+//
+// # JSON
+// The JSON representation of an `Any` value uses the regular
+// representation of the deserialized, embedded message, with an
+// additional field `@type` which contains the type URL. Example:
+//
+//     package google.profile;
+//     message Person {
+//       string first_name = 1;
+//       string last_name = 2;
+//     }
+//
+//     {
+//       "@type": "type.googleapis.com/google.profile.Person",
+//       "firstName": <string>,
+//       "lastName": <string>
+//     }
+//
+// If the embedded message type is well-known and has a custom JSON
+// representation, that representation will be embedded adding a field
+// `value` which holds the custom JSON in addition to the the `@type`
+// field. Example (for message [google.protobuf.Duration][google.protobuf.Duration]):
+//
+//     {
+//       "@type": "type.googleapis.com/google.protobuf.Duration",
+//       "value": "1.212s"

+// A URL/resource name whose content describes the type of the
+// serialized message.
+//
+// For URLs which use the schema `http`, `https`, or no schema, the
+// following restrictions and interpretations apply:
+//
+// * If no schema is provided, `https` is assumed.
+// * The last segment of the URL's path must represent the fully
+//   qualified name of the type (as in `path/google.protobuf.Duration`).
+// * An HTTP GET on the URL must yield a [google.protobuf.Type][google.protobuf.Type]
+//   value in binary format, or produce an error.
+// * Applications are allowed to cache lookup results based on the
+//   URL, or have them precompiled into a binary to avoid any
+//   lookup. Therefore, binary compatibility needs to be preserved
+//   on changes to types. (Use versioned type names to manage
+//   breaking changes.)
+//
+// Schemas other than `http`, `https` (or the empty schema) might be
+// used with implementation specific semantics.
+//
+// Types originating from the `google.*` package
+// namespace should use `type.googleapis.com/full.type.name` (without
+// schema and path). A type service will eventually become available which
+// serves those URLs (projected Q2/15).

+//     paths: "f.a"
+//     paths: "f.b.d"
+//
+// Here `f` represents a field in some root message, `a` and `b`
+// fields in the message found in `f`, and `d` a field found in the
+// message in `f.b`.
+//
+// Field masks are used to specify a subset of fields that should be
+// returned by a get operation or modified by an update operation.
+// Field masks also have a custom JSON encoding (see below).
+//
+// # Field Masks in Projections
+// When used in the context of a projection, a response message or
+// sub-message is filtered by the API to only contain those fields as
+// specified in the mask. For example, if the mask in the previous
+// example is applied to a response message as follows:
+//
+//     f {
+//       a : 22
+//       b {
+//         d : 1
+//         x : 2
+//       }
+//       y : 13
+//     }
+//     z: 8
+//
+// The result will not contain specific values for fields x,y and z
+// (there value will be set to the default, and omitted in proto text
+// output):
+//
+//
+//     f {
+//       a : 22
+//       b {
+//         d : 1
+//       }
+//     }
+//
+// A repeated field is not allowed except at the last position of a
+// field mask.
+//
+// If a FieldMask object is not present in a get operation, the
+// operation applies to all fields (as if a FieldMask of all fields
+// had been specified).
+//
+// Note that a field mask does not necessarily applies to the
+// top-level response message. In case of a REST get operation, the
+// field mask applies directly to the response, but in case of a REST
+// list operation, the mask instead applies to each individual message
+// in the returned resource list. In case of a REST custom method,
+// other definitions may be used. Where the mask applies will be
+// clearly documented together with its declaration in the API.  In
+// any case, the effect on the returned resource/resources is required
+// behavior for APIs.
+//
+// # Field Masks in Update Operations
+// A field mask in update operations specifies which fields of the
+// targeted resource are going to be updated. The API is required
+// to only change the values of the fields as specified in the mask
+// and leave the others untouched. If a resource is passed in to
+// describe the updated values, the API ignores the values of all
+// fields not covered by the mask.
+//
+// In order to reset a field's value to the default, the field must
+// be in the mask and set to the default value in the provided resource.
+// Hence, in order to reset all fields of a resource, provide a default
+// instance of the resource and set all fields in the mask, or do
+// not provide a mask as described below.
+//
+// If a field mask is not present on update, the operation applies to
+// all fields (as if a field mask of all fields has been specified).
+// Note that in the presence of schema evolution, this may mean that
+// fields the client does not know and has therefore not filled into
+// the request will be reset to their default. If this is unwanted
+// behavior, a specific service may require a client to always specify
+// a field mask, producing an error if not.
+//
+// As with get operations, the location of the resource which
+// describes the updated values in the request message depends on the
+// operation kind. In any case, the effect of the field mask is
+// required to be honored by the API.
+//
+// ## Considerations for HTTP REST
+// The HTTP kind of an update operation which uses a field mask must
+// be set to PATCH instead of PUT in order to satisfy HTTP semantics
+// (PUT must only be used for full updates).
+//
+// # JSON Encoding of Field Masks
+// In JSON, a field mask is encoded as a single string where paths are
+// separated by a comma. Fields name in each path are converted
+// to/from lower-camel naming conventions.
+//
+// As an example, consider the following message declarations:
+//
+//     message Profile {
+//       User user = 1;
+//       Photo photo = 2;
+//     }
+//     message User {
+//       string display_name = 1;
+//       string address = 2;
+//     }
+//
+// In proto a field mask for `Profile` may look as such:
+//
+//     mask {
+//       paths: "user.display_name"
+//       paths: "photo"
+//     }
+//
+// In JSON, the same mask is represented as below:
+//
+//     {
+//       mask: "user.displayName,photo"
+//     }
