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. Change-Id: Ie5083750755f5180a8a785b24fe67dbf9195cd10

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.

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.
