73bbc9eda8 charge_manager: Request power swap when switching from dual-role override port
Ports should have source roles by default, and should go back to being
sources once we stop charging from them.

BUG=chrome-os-partner:31195
TEST=Manual on Samus. Connect Samus to dual-role port. Set override
port, verify that Samus charges. Attach dedicated charger, verify that
the dual-role port becomes a charge source again. Also pass unit tests.
BRANCH=Samus

86835f7067 charge_manager: Allow board to reject a selected charge port
Modify board_set_active_charge_port to return status indicating whether
the selected charge port was rejected. If rejected, zero out its
available charge and attempt to select a different charge port.

Also, reduce the length of related console prints.

BUG=chrome-os-partner:34677
TEST=Manual on Samus. Plug C-to-Arec into port 1, verify that charge
manager does not select port 1 as active and charging icon is not seen
in OS.

6f010b635d charge_manager: Add delayed port override for role swap
If override charge is selected on a port currently acting as a charge
source, but the attached device is also capable of acting as a source,
request a charge role swap and initiate a pending delayed port override.
If the role swap completes successfully and a charge source is found,
the selected port will become the override port. If the role swap fails
or no charge source is found within 2 seconds, the delayed port override
will be lost.

BUG=chrome-os-partner:28343,chrome-os-partner:31195
TEST=Manual on Samus. Connect two Samus units together through charge
ports.
"pd 1 swap power" - put port on test device into source role
"chgoverride 1" - set charge override, verify that role swap takes
effect and charge manager selects PD charge source, 900mA @ 5V
Disconnect charge cable, verify that charge manager goes back to not
charging.

2a9a859655 pd: if our request is rejected, go to SNK_READY
If our request is rejected, go to SNK_READY, but don't set
explicit contract flag.

This also changes charge manager slightly to avoid new power
request loops. A new power request is only requested if the
charge port changes, or if the active charge port changes its
voltage/current offering. A new power request does not occur
if the current ceiling changes, since the existing contract
still suffices.

TEST=make buildall. use samus and make sure we negotiate for 20V
as normal. modify zinger to send a REJECT and make sure we go from
PD_STATE_SNK_REQUESTED to PD_STATE_SNK_READY and explicit contract
bit is 0.

BUG=chrome-os-partner:32003
BRANCH=Samus
TEST=Manual on Samus. Insert PD charger in port1 and BC1.2 charger in

./ectool --name=cros_pd chargeoverride 0 --> Charges from port 0
./ectool --name=cros_pd chargeoverride off --> Charges from port 1
./ectool --name=cros_pd chargeoverride dontcharge --> No charge port
./ectool --name=cros_pd chargeoverride 1 --> Charges from port 1
./ectool --name=cros_pd chargeoverride 2 --> Correctly returns error

8862b6aaf1 charge_manager: Don't charge from dual-role capable ports
Don't charge from dual-role capable ports, unless an override is set to
force charge. Also, if an override is set to charge from a dual-role
capable port and a dedicated charger is attached, remove the override.

will always be selected as the charge port, if any charge supplier is
