Removal of mblock and inband code

I noticed this in a recent commit:

Remove mblock library. We hardly knew 'ye.

This commit removes all mblock and inband code.

Is a new message passing interface usable with usrp-1 in place yet?

I was just working on getting the inband code working again to be able
to do timestamped rx and tx on usrp-1?
