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.

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.
BUG=b/23084294
TEST=grep 'Chromium OS Authors' doesn't find anything.

update_engine: Handle moved and zero blocks in payload generation.
Delta generation uses only the file name to detect when files changed.
Therefore, renaming a file doesn't get detected and the new name is
assumed to be a new file. On the other hand, free-space blocks are
often just zeros so they can be easilly encoded independently from the
rest.
This patch detects blocks that moved and blocks with zeros and handles
those blocks beforehand regardless of where are they in the filesystem
(file data, metadata, free space, etc). For blocks that moved,
SOURCE_COPY or MOVE operations are created as needed. For blocks with
zeros we use REPLACE_BZ operations.
Blocks processed in this way will be excluded from other files,
metadata or free space processing done. This solves perfomance issues
when trying to process with bsdiff files with very long runs of zeros.
CQ-DEPEND=CL:283643
BUG=chromium:504445
TEST=Unittest added. Run delta_generator between cid canary 7195 and
7201 and it doesn't take forever to finish.
