GPIO I2C rework Reqrite bitbanging I2C implementation. New code improves stop/start condition handling, and gives more accurate input line level. Introduce intermediate abstraction layer for I2C bitbanging that is not connected via a GPIO port. Signed-off-by: Paul Brook <paul@codesourcery.com>

hw: include hw header files with full paths Done with this script: cd hw for i in `find . -name '*.h' | sed 's/^..//'`; do echo '\,^#.*include.*["<]'$i'[">], s,'$i',hw/&,' done | sed -i -f - `find . -type f` This is so that paths remain valid as files are moved. Instead, files in hw/dataplane are referenced with the relative path. We know they are not going to move to include/, and they are the only include files that are in subdirectories _and_ move.
