Revert "Add functions to allow update over cellular (including tethered connection)"
This reverts commit 4b0d6032cbb86ce488c03b31936cda31283f97e3.
Bug: 62366504
Test: GmsCore sees the old status code (i.e. UPDATED_NEED_REBOOT == 6).

Add functions to allow update over cellular (including tethered connection)
- Add an update state NEED_PERMISSION_TO_UPDATE which is broadcasted along
with the update info (version and size) when |OmahaRequestAction| aborts
update due to cellular connection. So the state transition will be:
IDLE->CHECKING_FOR_UPDATE->NEED_PERMISSION_TO_UPDATE->REPORTING_ERROR_EVENT
->IDLE
(The Chrome UI prompts an alert window showing update size and asks user
whether to proceed upon receiving this state.)
- Add a dbus interface to set update over cellular target
(kPrefsUpdateOverCellularTargetVersion and kPrefsUpdateOverCellularTargetSize).
The target is the one received by Chrome UI in NEED_PERMISSION_TO_UPDATE
broadcast. By sending the target back with the dbus call, update engine can
double check the target with the server to make sure there's no new server
push after NEED_PERMISSION_TO_UPDATE is broadcasted to Chrome UI.
(This dbus call is invoked when the user chooses to proceed to update at the
alert window. The dbus call is followed by another dbus call |AttemptUpdate|)
- So, the the decision tree as to whether to allow update over cellular
connection has changed to:
IF (device policy DeviceUpdateAllowedConnectionTypes set)
follow device policy's decision
ELSE IF (kPrefsUpdateOverCellularPermission set to true)
allow update
ELSE IF (Either kPrefsUpdateOverCellularTargetVersion or
kPrefsUpdateOverCellularTargetSize is not set, or they are set but do not
match the version and size in |OmahaResponse| retrieved by
|OmahaRequestAction|)
disallow update, and broadcast NEED_PERMISSION_TO_UPDATE
ELSE
allow update
ENDIF
- This decision making happens at |OmahaRequestAction| after |OmahaResponse| is
retrieved. Since we want to separate the device policy check with the user
preferences check which depends on |OmahaResponse| during checking for update,
we modify ConnectionManager::IsUpdateAllowedOver by moving the user preferences
check to |OmahaRequestAction|. Thus, the function by default returns true for
cellular connection if device policy is not set.
- Corner case:
Adding kPrefsUpdateOverCellularPermission and
kPrefsUpdateOverCellularTargetSize seems to complicate the logic here. But
they could effectively solve a corner case where the target does not match
|OmahaResponse| due to new server push after broadcasting
NEED_PERMISSION_TO_UPDATE. In that case, we simply broadcast
NEED_PERMISSION_TO_UPDATE again along with new update info.

Split payload application code into a subdirectory.
This patch splits from the main libupdate_engine code the part that
is strictly used to download and apply a payload into a new static
library, moving the code to subdirectories. The new library is divided
in two subdirectories: common/ and payload_consumer/, and should not
depend on other update_engine files outside those two subdirectories.
The main difference between those two is that the common/ tools are more
generic and not tied to the payload consumer process, but otherwise they
are both compiled together.
There are still dependencies from the new libpayload_consumer library
into the main directory files and DBus generated files. Those will be
addressed in follow up CLs.

Move UpdateStatus and helpers to dedicated files
This allows us to easily share it between the update_engine proper
and a forthcoming client library.
