This reverts commit ca3674b7d5.
While there are savings, it ends up being to easy/common to run into issues with
AppStore validation since the selector usage now appears to be a possible match
for private apis vs. for selectors/properties in the generated code.
Adds an option to protoc `--objc_opt=elide_message_metadata` to remove all the property
metadata from message classes. This significantly reduces the codegen size of the clases.
The downside is that iterating through properties using objective c runtime calls will no
longer function. This is mitigated by the fact that most (all?) of the information that
folks are interested in can be extracted via the message descriptor.
We do this by defining our own classes using the `GPB_MESSAGE_SUBCLASS_IMPL` macro.

In some cases proto files that want/need to use the objc_class_prefix option have
types that already have the prefix on a subset of their names. In this case we don't
want to duplicate the prefix.
Added tests for this (and prefixes in general).
- Check the parent file options for deprecation when deciding to tag Messages
and Enums as deprecated.
- Within the generated source push/pop the warning for implementing deprecated
things around a deprecated class implementation.
- Annotate the methods generated for extension fields as deprecated.
- Add a testing .proto file that covers deprecated fields, messages, enums,
enum values and compile it into the unittests to confirm things compile
cleanly.
- Add a testing .proto file that uses the file level option to make everything
deprecated and compile it into the unittests to confirm things compile
cleanly.
- Capture the ObjC prefix used when generating the the file.
- Track the containing type on descriptors.
- Mark descriptors where the message class name got a suffix added to it.
- Expose a fullName property on Descriptors.
- Add helpers for packing/unpacking Any messages.
- Bump the ObjC runtime version number. Since we added methods and invoke them
in the generated code, ensure the code is running against a matching version.
Otherwise, someone could compile against headers, but run with a framework
that is older and get unknown selector failures. This should trip clearer
messaging.

At generation time, walk the file's dependencies to see what really contains
extensions so we can generate more minimal code that only links together the
roots that provided extensions. Gets a bunch of otherwise noop code out of
the call flow when the roots are +initialized.
NOTE: This is a binary breaking change as structure sizes have changed size
and/or order.
- Drop capturing field options, no other options were captured and other mobile
targeted languages don't try to capture this sort information (saved 8
bytes for every field defined (in static data and again in field descriptor
instance size data).
- No longer generate/compile in the messages/enums in descriptor.proto. If
developers need it, they should generate it and compile it in. Reduced the
overhead of the core library.
- Compute the number of has_bits actually needs to avoid over reserving.
- Let the boolean single fields store via a has_bit to avoid storage, makes
the common cases of the instance size smaller.
- Reorder some flags and down size the enums to contain the bits needed.
- Reorder the items in the structures to manually ensure they are are packed
better (especially when generating 64bit code - 8 bytes for every field,
16 bytes for every extension, instance sizes 8 bytes also).
- Split off the structure initialization so when the default is zero, the
generated static storage doesn't need to reserve the space. This is batched
at the message level, so all the fields for the message have to have zero
defaults to get the saves. By definition all proto3 syntax files fall into
this case but it also saves space for the proto2 that use the standard
defaults. (saves 8 bytes of static data for every field that had a zero
default)
- Don't track the enums defined by a message. Nothing in the runtime needs it
and it was just generation and runtime overhead. (saves 8 bytes per enum)
- Ensure EnumDescriptors are started up threadsafe in all cases.
- Split some of the Descriptor initialization into multiple methods so the
generated code isn't padded with lots of zero/nil args.
- Change how oneof info is feed to the runtime enabling us to generate less
static data (8 bytes saved per oneof for 64bit).
- Change how enum value informat is capture to pack the data and only decode
it if it ends up being needed. Avoids padding issues causing bloat of 64bit,
and removes the needs for extra pointers in addition to the data (just the
data and one pointer now).
- Add more to the ObjC dir readme.
- Merge the ExtensionField and ExtensionDescriptor to reduce overhead.
- Fix an initialization race.
- Clean up the Xcode schemes.
- Remove the class/enum filter.
- Remove some forced inline that were bloating things without proof of performance wins.
- Rename some internal types to avoid conflicts with the well know types protos.
- Drop the use of ApplyFunctions to the compiler/optimizer can do what it wants.
- Better document some possible future improvements.
- Add missing support for parsing repeated primitive fields in packed or unpacked forms.
- Improve -hash.
- Add *Count for repeated and map<> fields to avoid auto create when checking for them being set.
