Current asserts on AumBootState object in aum_boot_state_*() functions
ends up when there is no boot state backend available, i.e. for UEFI AMD64
targets, by trying to rollback the OS.
Replacing those asserts by tests returning default values allows AUM to
handle this case gracefully and with better debug message.

New `uboot.cnt` file format appears in u-boot 2019.01+dfsg-7co7.

AUM should be able to work with both legacy and new u-boot, and their
`uboot.cnt` respective file formats. Otherwise AUM consider the file is
corrupted and triggers a rollback.
This commit allows to update AUM in a first step, work with the current
u-boot before upgrading it.

After a successful upgrade, multiple failures during boot sequence may
trigger the u-boot altbootcmd process which will trigger an unexpected
rollback.
This patch adds a version and an upgrade_available entries to the
bootcount file to enable/disable the bootcount check.

Calling the ostree_sysroot_cleanup() function with initialized
error variable cause assertion:
  "_ostree_repo_lock_push: assertion 'error == NULL || *error == NULL' failed"

This issue is preventing correct repository prune in case of any problem
occurred during upgrade.

We do not want to mark the upgrade process as failed in case of any error
acquired during cleanup, hence just drop a warning message.

On the target device at least one remote must have the correct
'collection-id' field and branch listed in 'ostree.ref-binding'
metadata of inlined commit from upgrade bundle.

Function 'aum_get_target_checksum()' has been renamed to 'aum_get_target_metadata()'

The bootcount will soon change to be store on the ext filesystem
in /boot/failures. The formar is two bytes { 0xbc, <bootcount> }.
To handle this new format, the update manager needs an update.
The bootcount is no longer saved, only u-boot will have to write it.
The upgrade_available variable is not available, so the file is written
at each boot.
The bootlimit is hardcoded in the update-manager and must stay in sync
with u-boot.
