    core: Add support for passing PSM as OBEX port

    As OBEX can now use L2CAP as transport, -O/--obex option should accept
    values other than RFCOMM channel, so values over 31 are now interpreted
    as PSM.

    lib: Add Key Size information to the security information

    Since some time the kernel has the capability to return the length of
    the key that was used to encrypt the link.

    This patch exposes that field to userspace so more applications can take
    decisions based on this information.
