This adds some new functions: sshbuf_from(), sshbuf_fromb() and sshbuf_froms() that create new buffers from a read-only blob, the contents of a buffer and the contents of a string in a buffer respectively. In all cases the memory contents are not copied - the new buffer, which is read-only, just refers to the original location in memory.
