This CL replaces
* 30 instances of DISALLOW_COPY_AND_ASSIGN(Foo),
* 1 instance of DISALLOW_IMPLICIT_CONSTRUCTORS(Foo),
in Zucchini with:
Foo() = delete; // DISALLOW_IMPLICIT_CONSTRUCTORS only.
Foo(const Foo&) = delete;
const Foo& operator=(const Foo&) = delete;
All base/macros.h includes are removed.

ClusterFuzz found a 32-bit PE file that triggers DCHECK(). The cause (in
DisassemblerWin32):
* ParseAndStoreRelocBlocks() reads malformed reloc region and rejects
it, but writes bad result to |reloc_region_| (with kInvalidOffset).
* MakeReadRelocs() passes the invalid |reloc_region_|, which causes
uint32_t overflow (for 32-bit size_t), and triggering DCHECK().
* MakeWriteRelocs() was not reached, but has similar problem.
Main fix:
* Initialize |reloc_region_| to invalid state.
* In ParseAndStoreRelocBlocks():
* On first run: Only write |reloc_region_| on success.
* On later runs: Return validity of |reloc_region_|.
* In MakeReadRelocs() and MakeWriteRelocs(): Already calls
ParseAndStoreRelocBlocks(). Change this to return vacuous
ReferenceReader / ReferenceWriter on failure, i.e., if
|reloc_region_| is invalid.
* Need to add EmptyReferenceWriter for this.
DisassemblerWin32 is also too lax in dealing with malformed input, so
this CL also implments more stringent checks:
* Disallow ImageSectionHeader (+ ImageOptionalHeader) from overlapping
with ImageDOSHeader.
* Apply more stringent checks for |size_of_optional_header| and
|number_of_rva_and_sizes|: Consistency and bounds.

Creates Disassembler that recognises and parses ELF format. For now, it only supports Intel architeture. Support for Arm will be added in follow-up CLs.

This allows compilers targeting the MS ABI to select the correct
inheritance model for the member function pointer types ReaderFactory
and WriterFactory using the complete type of Disassembler. It will
allow us to enable the new Clang flag -fcomplete-member-pointers
globally.

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.
