e778adae83 Change VbExEc functions to take a devidx parameter
This will be used in subsequent CLs to support PD software sync.  For
now, only devidx=0 is used.

This changes the external vboot API, so must be checked in at the same
time as changes to the u-boot and depthcharge implementations.  For
now, those implementations should simply check if devidx=0 and fail if
it's not.

bbc7606329 Fix jumping EC from RO to RW if disable-jump was called on previous boot
It's possible for the AP to get updated and remove the RO-normal flag
without needing to update EC-RW firmware - for example, if it only
needs to update the BIOS.  In this case, the EC doesn't need update,
but does need to jump to its RW firmware.  But if the EC is already
booted RO-normal with jump disabled, it will refuse that request and
go to recovery mode.

The fix is simply to check if the request to jump to RW requires the
EC to cold-boot first, and pass through that error code to the caller.

2500185a83 Add memory leak checking
Add checks that the vboot library does not leak memory. This works by
tracking VbExMalloc() calls and making sure that they have an associated
VbExFree().

Adjust host_signature to use VbExFree() instead of free(), so that this
scheme works correctly for existing code.

19c996909d EC software sync no longer checks for shutdown requested
This means that in normal mode the system will boot all the way to the
OS before shutting down.

In developer or recovery modes, the BIOS screens will still check for
shutdown requested and shut down if so.  This is necessary in
developer mode for security reasons, and because there's no guarantee
that a dev OS will still pay attention to the lid switch.

886a9047f0 Software sync checks for shutdown-requested in all code paths
Previously,
1) AP-RO, EC-RO -> checked
2) AP-RW, EC-RO transition to EC-RW -> checked
3) AP-RW, EC-RW already -> NOT checked

Now, (3) calls VbExIsShutdownRequested() as well.

This fix is needed to avoid inconsistent behavior of software sync
after we ship a RW update.

Whether we *should* actually shut down or not based on how/why we
booted is a separate issue to be addressed by the U-boot
implementation of VbExIsShutdownRequested() in a separate CL.

BUG=chromium-os:38645
BRANCH=all
TEST=make runtests

Manual testing also possible - force AP-RW firmware, then reboot with
lid closed.  Previously, the first boot would shut down because of
(2), but subsequent reboots of the AP only wouldn't because of (3).
