Fixes a CHECK failure in Zucchini Apply found by ClusterFuzz.
Scenario:
A disassembler parses an image element and shrinks it to be the
understood size. Apply expects that this understood size is identical to
the size of the element it is trying to patch. This expectation will
always hold for "good" patch data but for an arbitary patch may not.
This results in a CHECK failure when getting reference writers.
Solution:
After parsing, check that the disassembler sizes match their respective
image sizes. Fail to Apply and print an error message if this is not the
case.

depend on Disassembler.
The number of CreateEquivalenceMap() iterations used be constant
kNumIteraitons = 2. This CL makes the value depend on architecture.
Current assignment:
- DisassemblerNoOp: 1, since no pointers are identified (though in this
case, CreateEquivalenceMap() should not be called).
- DisassemblerWin32: 2.
Upcoming DisassemblerDex will use 4.
Also applying generic cleanups on headers and comments.

(Use "git log --follow" to see older revisions of files).
/components/ is the most logical place to put Zucchini, which only
depends on /base and /testing/gtest. This move also enables Zucchini to
be used by the Component Updater. Details:
- Move all files; run the following to change deps and guards:
sed 's/chrome\/installer/components/' *.cc *.h -i
sed 's/CHROME_INSTALLER/COMPONENTS/' *.cc *.h -i
- Sorting works out pretty well!
- Change all 'chrome/installer/zucchini' to 'components/zucchini'
throughout other parts of the repo; sort if necessary.
- Fix 6 'git cl lint' errors.
- Change 1 Bind() usage to BindRepeated().
- Update OWNER.
