delta_generator: Use REPLACE_XZ in deltas when allowed.
This patch moves the generation of the best allowed full operation to a
new function which now includes ZERO, REPLACE, REPLACE_BZ and REPLACE_XZ
when allowed. This function is used to produce a full operation
whenever it is needed in the "full" payload generator and the AB "delta"
payload generator.
Bug: 24578399
TEST=brillo_update_payload generated REPLACE_XZ operations for a delta payload that was using REPLACE_BZ operations and merged them.
TEST=brillo_update_payload generated a full payload with REPLACE, REPLACE_BZ and REPLACE_XZ operations.
TEST=Updated unittests.

Implement REPLACE_XZ on the update_engine.
This patch introduces the REPLACE_XZ operation, very similar to
REPLACE_BZ but using the XzExtentWriter instead. Minor cleanup of the
growing list of operations included in this patch.

Test: Added unittests.

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.

TEST=grep 'Chromium OS Authors' doesn't find anything.

update_engine: Move InstallOperation to the top level.
The InstallOperation message in the protobuf is a nested message
inside the DeltaArchiveManifest message, making all references to
operation types be very long names like
DeltaArchiveManifest_InstallOperation_Type_REPLACE_BZ while most other
messages are not nested in the DeltaArchiveManifest message.
To improve readability and to prepare for future update metadata
changes, this patch moves the InstallOperation message to the top level
and replaces all references to operation types with the new shorter
version like InstallOperation::REPLACE_BZ.
This change only impacts the scope of the generated classes and the
serialized format of the protobuf. This exact same question was
addressed by protobuf maintainers here:
https://groups.google.com/forum/#!topic/protobuf/azWAPa6hP4A
Finally coding style and indentation was automatically updated due to
the shorter names.
BUG=b:23179128
TEST=Unittest still pass.

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.

TEST=Updated unittest to use extents.

update_engine: Merge contiguous operations (reprise).
This is reapplying CL:269604 with a small fix that prevents it from
adding spurious src_length fields when merging payload operations. This
also revises relevant unit tests to catch the said error. The original
change is described below.
Merges operations of type SOURCE_COPY, REPLACE, or REPLACE_BZ if they
have the same type, are contiguous, have only one destination extent,
and their combined block count does not exceed the chunk size.

Revert "update_engine: Merge contiguous operations."
This reverts commit 6a3ea94766bb4972abbd629779914d80dada1245.
The CL is suspected to close the tree due to paygen failures.
See comments inline (delta_diff_generator.cc) for the culprit.

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.
