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.
Bug: 27859604
TEST=Added logging and deployed an update to brillo, devices are marked RO/RW as needed during a delta update.

Parse postinstall program progress updates.
In Android postinstall is expected to take a long time in common cases.
This patch allows the postinstall program to report back to the updater
a progress indication, which will then be forwarded to all the clients
listening. These progress updates are part of the FINALIZING status.
Bug: 27880754
TEST=Added unittests. Deployed an update to an edison-eng and post-install reported progress back with the postinstall_example.

Check if zlib is compatible.
Add a --zlib_fingerprint flag in delta_generator to check if the zlib of
source image is compatible, and only enable IMGDIFF operation if it is.
Test: Added unittest to check /etc/zlib_fingerprint

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.
Bug: 27177071
TEST=Deployed a postinstall script with `ls -laZ`, contents show "postinstall_file".

Parse postinstall parameters from the payload metadata.
Payload v2 includes a description of the post-install command it should
run, while in payload v1 we use the default values. This patch mounts
the partition on the new top-level directory called /postinstall that
should already be created.

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.

TEST=`update_engine_client --update` prints the error message in a non-Brillo device.

CPULimiter: Refactor class to manage the CPU limitation.
This new class replaces the functionality embedded in UpdateAttempter
that limits the max CPU usage allowed by update_engine. This refactor
helps reusing this class outside of the brillo UpdateAttempter.

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.

common: Split out metrics utils from utils.cc.
The utility functions to convert error codes and network settings to
the types defined by the metrics framework are split out the utils.cc
file. These tools are only used by the update_engine daemon to report
back metrics on an update check.

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.
