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. Bug: 25197634 Test: FEATURES=test emerge-link update_engine; `mm` on Brillo. Change-Id: Id8d0204ea573627e6e26ca9ea17b9592ca95bc23

Re-license update_engine to Apache2 This patch automatically replaced the license on all text files from Chromium OS (BSD style) to AOSP (Apache2), keeping the original year as a reference. The license header was added to .gyp and .gypi files, the NOTICE was replaced with a copy of the Apache2 license and MODULE_LICENSE_* file was updated.

update_engine: UM: Separate global P2P usage from payload-specific attributes. This change is needed for two reasons: (a) The decision regarding the global P2P enabled state and those pertaining to whether individual payloads may be downloaded and/or shared via P2P have distinct and not necessarily nested lifespans. (b) Some parts of the update engine are concerned with the former and some with the latter, and so we need separate entry points in the Update Manager to accommodate that. This also introduces two Omaha-derived values, denoting whether P2P downloading and/or sharing should be disabled for the current payload, into the UpdateCanStart policy.

update_engine: UM: Properly handle update download deterrents. The UpdateCanStart policy request needs to satisfy two related requirements: * It must allow the caller to proceed with the update even if some forms of download are not allowed (for example, HTTP/HTTPS download blocked due to scattering) but other are allowed (for example, P2P). * It needs to assess all the input provided and, upon returning successfully, convey any new values that pertain to downloading of the update payload and that need to be persisted (such as the download URL, backoff and scattering values, and so on). The caller in turn is assured that, having successfully returned, the policy has indeed considered all state and it is safe to clear parts of it (such as the download error history). This change ensures that the policy suppresses scattering and backoff decisions if P2P download is allowed. This only suppresses the final decision, but otherwise still returns whatever URL index and error count that were inferred. It further adjusts the way in which various download deterrents (check due, scattering, backoff) are handled, deferring responses to the very end of the evaluation and thus returning a complete result.

update_engine: UM: Policy to distinguish between P2P downloading and sharing. Previously, the UpdateCanStart policy returned a single Boolean, indicating whether "P2P is allowed". However, the policy has been incorrectly reproducing decisions made by current code, whereas P2P sharing is always allowed (if P2P is enabled) but P2P downloading has additional limitations. This CL introduces distinct flags for both downloading and sharing, and reasons about them specifically. This also adds a constraints whereas P2P downloading is allowed for non-interactive updates only. BUG=chromium:420732 TEST=Unit tests.

update_engine: UM: Change policy argument from const ref to value. It turns out that passing an argument by reference to UpdateCanStart via UpdateManager::AsyncPolicyRequest is a pain. Furthermore, given that the policy is async by definition, it makes little sense to hand it a const reference argument. This changes the said argument to be passed by value.

update_engine: UM: Incorporate backoff logic in UpdateCanStart. This change adds backoff computation logic to UpdateCanStart. For the most part, it is extending a private policy call (UpdateDownloadUrl) to account for previously enacted backoff periods and to compute new ones when an update failure is identified (accordingly, it is now called UpdateBackoffAndDownloadUrl). To conform with the pure nature of policy implementations, yet minimizing the amount of "state" that needs to be managed and persisted by the updater, we now consider download errors in bulks defined by the most recent update failure (namely, the point in time when all URLs where tried and failed). The updater is expected to keep track of the update failure count, setting it to zero when a new update is seen, and incrementing it (and recording the time it was incremented) when told to do so by the policy. We therefore make some adjustments to the policy API and its usage semantics. BUG=chromium:396148 TEST=Unit tests.

UpdateManager: Move logic from UpdateCanStart to UpdateCheckAllowed. The following should be part of the policy that is consulted before performing an update check: 1) Whether updates are disabled by device policy. 2) Whether a specific target channel is dictated by the device policy. This CL moves it from UpdateCanStart into UpdateCheckAllowed. Another change is renaming the output construct of UpdateCanStart into 'UpdateDownloadParams'; this is in line with the naming of the output struct of UpdateCheckAllowed, and reflects the fact that it contains information regarding the download of an update, to be used by the caller.

UM: Policy for deciding download URL. This adds a new private policy (UpdateDownloadUrl) for determining which download URL should be used for obtaining the update payload. We further extend an existing public policy (UpdateCanStart) to return the download URL details, based on the current URL index and the number of failures associated with it. This renders the explicit notion of "HTTP download allowed" in the return value unnecessary: If HTTP is not allowed, then HTTP URLs will not be considered. We also implement logic for logging the start/end of a policy evaluation, so that intermediate log messages emitted during evaluation have a clear context. BUG=chromium:358329 TEST=Unit tests.
