The ctype option instructs the C++ code generator to use a different representation of the field than it normally would. See the specific options below. This option is not yet implemented in the open source release -- sorry, we'll try to include it in a future version!
The packed option can be enabled for repeated primitive fields to enable a more efficient representation on the wire. Rather than repeatedly writing the tag and type for each element, the entire array is encoded as a single length-delimited blob. In proto3, only explicit setting it to false will avoid using packed encoding.
The jstype option determines the JavaScript type used for values of the field. The option is permitted only for 64 bit integral and fixed types (int64, uint64, sint64, fixed64, sfixed64). By default these types are represented as JavaScript strings. This avoids loss of precision that can happen when a large value is converted to a floating point JavaScript numbers. Specifying JS_NUMBER for the jstype causes the generated JavaScript code to use the JavaScript "number" type instead of strings. This option is an enum to permit additional types to be added, e.g. goog.math.Integer.
Should this field be parsed lazily? Lazy applies only to message-type fields. It means that when the outer message is initially parsed, the inner message's contents will not be parsed but instead stored in encoded form. The inner message will actually be parsed when it is first accessed.
This is only a hint. Implementations are free to choose whether to use eager or lazy parsing regardless of the value of this option. However, setting this option true suggests that the protocol author believes that using lazy parsing on this field is worth the additional bookkeeping overhead typically needed to implement it.
This option does not affect the public interface of any generated code; all method signatures remain the same. Furthermore, thread-safety of the interface is not affected by this option; const methods remain safe to call from multiple threads concurrently, while non-const methods continue to require exclusive access.
Note that implementations may choose not to check required fields within a lazy sub-message. That is, calling IsInitialized() on the outer message may return true even if the inner message has missing required fields. This is necessary because otherwise the inner message would have to be parsed in order to perform the check, defeating the purpose of lazy parsing. An implementation which chooses not to check required fields must be consistent about it. That is, for any particular sub-message, the implementation must either *always* check its required fields, or *never* check its required fields, regardless of whether or not the message has been parsed.
Is this field deprecated? Depending on the target platform, this can emit Deprecated annotations for accessors, or it will be completely ignored; in the very least, this is a formalization for deprecating fields.

The parser stores options it doesn't recognize here. See above.
