Add android support

[dati91]

Add bluetooth android support with blurdroid crate.

Also I moved the unimplemented code to the empty.rs file.
And there is an API change (get_object_path -> get_id).

This change is

And a question: this will break servo (because of the API change), or servo's lock file will save the day?

[dati91]

Also this will solve #8 (at least i think so)

[jdm]

Servo's lock file will prevent Servo from using a more recent revision.

@jdm Will you have a chance to take a look at this before you go on PTO, or would you like me to do so?

[jdm]

@larsbergstrom If you could take a look at it, that would make my life easier.

[larsbergstrom]

The code looks mostly fine to me! The only question I have is whether it works when you are compiling with target_os=linux but without feature=bluetooth enabled? It looks like there were a bunch more #cfg branches added in the first commit that fill out the non-linux side of things but that leaves linux-minus-bluetooth-feature, unless I'm misunderstanding and you expect those files not to be compiled at all.

[dati91]

Yeah you are right, I didn't handled the case when we turn the bluetooth feature off! I hope now everything is fine.

[larsbergstrom]

lgtm! Do you mind squashing it into more logical commits, and then we can land it? Thanks!
