Split transport specific files

Problem statement:
Currently several tens of pages worth of transport specification is situated in single file. Many parts of the specification are already maintained in separate files.

Such separate files enables better maintenance of the specification overall.

Solution:
Follow the approach similar to rest of the spec, and keep transport specific spec in their individual files.

This series is for fixing issue [1].
