transport: reformat flag #defines to be more readable

All of the #defines for the TRANSPORT_* flags are hardcoded to be
powers of two.  This can be error prone when adding a new flag and
is difficult to read.  Update these defines to instead use a shift
operation to generate the flags and reformat them.
