2730daa567 Comm interface now provides max I/O sizes and preallocated buffers 
The maximum packet / param size differs depending on interface and
protocol version.  Commands can now ask the comm interface what the
limits are, and can use preallocated buffers to avoid needless
malloc/free.

This is preparation for the common userspace EC interface. If/when that
appears, this will be ready.
