C binding for lmctfy

[monnand]

C binding for lmctfy.

• It requires protobuf-c to generate c code for .proto
• All function names prefixed by lmctfy_
• For any method which requires a protobuf generated class as its parameter or its return value, there will be two functions: one's name follows the original method name; another's name is suffixed by _raw. The _raw functions takes a serialized buffer to represent the protobuf generated object.
• Any method which returns a ::util::Status or ::util::StatusOr has a corresponding function in the c library which takes a struct status * as its first parameter. The status structure will be used as output. Those functions will also check the error code in the status structure before executing other code in the functions. If the error code is not zero, they will return immediately with the error code.

Can we move the includes into "/includes"? I think the c bindings implementation is still okay to have where it is.

I noticed that the parameter order does not follow the coding style (Should be input first then output). I will change them later.

Please take another look.

Besides those lines mentioned in the reviews, I made the following changes as well:

• Rearranged the layout of files, so that every .cc file has its corresponding header file.
• Changed the order of parameters of all functions.

I just made a rebase onto 0.4.5. Please take another look.

Thanks. Ignore the travis error - its not fully setup. There's a jenkins build and test that should be firing up.

Can one of the admins verify this patch?
