[PATCH 1/3] transport: refactor flag #defines to be more readable

[Brandon Williams <bmwill@google.com>]

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.  This patch refactors these defines to instead use a shift
operation to generate the flags.  This makes adding an additional flag
simpilar and makes the defines easier to read.
