Store raw payload hash blob in install plan.
We were using a custom sha256 pair in Omaha response, now that Omaha
has a standard hash_sha256 field in package, we should use that instead.
The difference is that hash_sha256 is encoded in hex instead of base64,
but the android payload property is still using base64, to be backward
compatible, we have to keep accepting base64 there, to avoid decoding
and then re-encoding to another encoding, we store the decoded raw hash.
Also removed the hash() related functions in HashCalculator, since it's
rarely used and the caller should encode it in whatever encoding they
want.
Also make use of RawHashOfBytes to simply code in a few places.

Unmount old postinstall mountpoint from previous runs.
When update_engine crashes, is killed or a developer runs
"stop update_engine" while we are waiting for postinstall to finish
the other partition will continue to be mounted (read-only) on the
/postinsall path. This will prevent to mount the new postinstall
step on top of it due to different SELinux labels when mounted and
unmounted. After failing to run postinstall due to the failed mount
operation we would cleanup the mountpoint, so this situation fixes
itself after one failed update attempt, which can then be resumed
from the very end.
This patch attempts to unmount /postinstall if a filesystem is mounted
there at the time we need to use the mountpoint.

Setup a temporary directory for update_engine_sideload.
When running update_engine_sideload from recovery, the default temp
directory (/data/misc/update_engine/tmp) is not available. This
directory is currently used to store a blob when applying a bspatch
from a child process. This patch uses /tmp/update_engine_sideload as
a temporary directory when running update_engine_sideload from recovery.

Mark block device as read-only before mounting.
Mounting a block device as read-only still allows the filesystem to
write to the block device, while keeping the user-facing filesystem
interface "read-only". This behavior will make dm-verity to fail after
reboot if any block is modified during postinstall.
This patch marks the block device as read-only before mounting it, and
marks them read-only or read-write before using them during the update.

TEST=Added logging and deployed an update to brillo, devices are marked RO/RW as needed during a delta update.

a progress indication, which will then be forwarded to all the clients
listening. These progress updates are part of the FINALIZING status.

Remove self-crashing logic.
update_engine used to report a crash when something with the omaha
response was really wrong. Nowadays the server side configuration is
automatic and these crashes trigger more on unrelated issues, such as
network problems. These extra crashes generate noise and hide the
volume on other more important crashes.
This patch disables this logic.

Mount the new system as 'postinstall_file' in postinstall.
When mounting the new filesystem on /postinstall, we need to override
the file attributes from the new system (unknown to the current selinux
policies) with a consistent label that will be used only in the context
of postinstall. This patch passes an extra option to mount(2) in
Brillo and Android to achieve this.

Android: Print the error code string from the client.
The update_engine_client needs to translate the numeric ErrorCode to a
string name that can be printed on the output. This patch moves the
ErrorCodeToString() function to a new error_code_utils.{h,cc} pair of
files so it can be included easily from the client binary and uses it
in the Android update_engine_client.

Move metrics time helpers to metrics_utils.
The metrics module reports metrics periodically, for which it needs to
keep track of the duration since some events (for example, the update
finished). These helpers were in the common/utils.h, but they rely on
the global SystemState to access both Prefs and Clock.
Since these helpers are specific to the metric reporting, this CL moves
them to the metrics_utils.h module.

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.
