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.

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: Sort full operations by destination.
The inplace generator moves all the full operations to the end of the
list. This patch sorts those operations by the destination.
This patch also cleans up the Vertex class by using the new
AnnotatedOperation class instead of the operation and file_name
separated.
BUG=None
TEST=Unittest still pass. minor_version=1 full operations appear in
order according to "cros payload".

update_engine: Use the FilesystemInterface to generate deltas.
This patch removes the FilesystemIterator used to iterate the file data
blocks, the metadata.{cc,h} files used to iterate the metadata blocks and
the ReadUnwrittenBlocks() method used to process the rest of the blocks.
Instead, these three cases are handled by the same DeltaReadFilesystem()
method using the FilesystemInterface abstraction for ext2.
The sub-file block handling was changed from (filename, offset, size) to
just the list of blocks (or Extents) and the parsing of the filesystem
was removed from the methods that produce operations. The filename is
kept just as a label for logging purposes.
This patch implies that the filesystem doesn't need to be mounted in
order to generate the payload, as all the data is accessed as blocks
in a partition. The mountpoint was removed from all the operations
generators, but it is still required to mount the old filesystem to
detect the minor version supported by the old update_engine. Also,
since the list of blocks is never accessed using the FIGETBSZ ioctl,
no payload_generator/ test require root privileges, nor the
delta_generator binary.

update_engine: Split Extent utils from graph_utils.
"Graph" related utils should only concern parts of the code using the
inplace generator, since other generators don't use a dependency graph.
This patch splits the Extent related utils from the graph related ones
creating a new extent_utils.h file.

update_engine: Refactor OperationsGenerator into a base class.
This refactor cleans up the interface of the algorithms that generate
the list of rootfs and kernel operations removing the mention of a
Graph from it. The Graph class is only used by the in-place generator
because it requires to keep track of dependencies between operations
reading or writting the same block. The full update generator, using
only REPLACE or REPLACE_BZ doesn't need to use a graph to do that, but
in order to reuse some code, the interface was hacked that way.
This patch now uses two vectors of "AnnotatedOperations", which are
a mere InstallOperation as defined by the .proto file plus a name
used for logging purposes only. Both rootfs and kernel operations
have now the same type on the interface, allowing to share common
functions handling those.

update_engine: Fix all the "using" declaration usage.
This patch removes unused "using" declarations, that is, declarations
included in a .cc file at a global scope such that "using foo::bar"
that later don't use the identifier "bar" at all.
This also unifies the usage of these identifiers in the .cc files
in favor of using the short name defined by the using declaration.
For example, in several cases the .h refer to a type like
"std::string" because using declarations are forbidden in header
files while the .cc includes "using std::string;" with the purpose
of just writting "string" in the .cc file. Very rarely, the full
identifier is used when a local name ocludes it, for example,
StringVectorToGStrv() and StringVectorToString() in utils.cc named
its argument just "vector" need to refer to std::vector with the
full name. This patch renames those arguments instead.
Finally, it also sorts a few lists of using declarations that weren't
in order.

Move payload generator files to payload_generator/ directory.
This creates a new subdirectory payload_generator/ with all the
payload generator specific files.
The SConstruct file is updated to continue building all the files
together, including those in the subdirectories, since some parts
of the update_engine are using parts of the payload generation code.
To reduce this code coupling, a new payload_constants.h file is
introduced, with few constants used on the payload definition by both
the payload generation and the payload performer.
Finally, includes are updated and in some cases removed when they
weren't used. Order of includes is also fixed to comply with the
style guide.
