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: Expose the update_engine.conf in the FilesystemInterface.
The old image contains a /etc/update_engine.conf file that states the
payload version supported by that image. Currently we read this file
directly from the mounted filesystem and parse its contents. To stop
mounting the filesystem we need to retrieve the information on this file
somehow.
This patch extends the FilesystemInterface with a method to load the
update_engine.conf settings from the filesystem and implemets it using
ext2fs on ext2 filesystems.

update_engine: Fix memory leak on new ext2_filesystem code.
ext2fs_get_pathname() allocates new memory to store the pathname and we
are supposed to free it. This patch adds the missing call to
ext2fs_free_mem().

update_engine: Remove unused IsIdempotentOperation().
All the minor-version=2 are idempotent, so since we switched to minor
version 2, this function becomes trivial now. This patch removes this
function from the code and moves the ExtentRanges class to the
payload_generator/ directory since now it is only used there.
BUG=None
TEST=Unittest still pass.

update_engine: Introduce FilesystemInterface abstraction.
The interaction with the filesystem in the payload generation process
is hard-coded in several places, making it hard to mock out or use a
different filesystem like squashfs for delta generation. For example,
the metadata, regular file data and non-file data are handled by three
different functions in a similar way, but with different code.
This patch introcudes a filesystem abstraction to map files or
pseudo-files (like the metadata, free-space, etc) into the same interface.
The interface includes three implementations: for parsing ext2 filesystems
using ext2fs (already used by the metadata parsing but not by the file
data processing), a raw one for monolitic partitions like the kernel
and a fake one used for testing without requiring to build/parse a real
ext2 filesystem.
