Since we don't support MSVC2013 anymore, we can be more
succinct when defining move constructors of compound types.

Motivation: reduce code complexity.
SkCanon stores SkPDFShader::State next to SkDFObject, not inside.
many places use sk_sp<T> rather than T* to represent ownership.
SkPDFShader::State no longer holds bitmap.
SkPDFShader::State gets move constructor, no longer heap-allocated.
Classes removed:
SkPDFFunctionShader
SkPDFAlphaFunctionShader
SkPDFImageShader

Motivation:
SkPDFStream and SkPDFSharedStream now work the same.
Also:
- move SkPDFStream into SkPDFTypes (it's a fundamental PDF type).
- minor refactor of SkPDFSharedStream
- SkPDFSharedStream takes unique_ptr to represent ownership

SkPDFUtils now has a special function (SkPDFUtils::AppendColorComponent)
just for writing out (color/255) as a decimal with three digits of
precision.
SkPDFUnion now has a type to represent a color component. It holds a
utint_8, but calls into AppendColorComponent to serialize.
Added a unit test that tests all possible input values.

Call drop() after calling emitObject() on top-level objects. In Debug
mode, assert that each object is emited exactly once by asserting that
emitObject is never called after drop(). Same for addResources().
To make sure that top level objects don't get deleted prematurely,
SkPDFObjNumMap takes a reference.
Motivation: save RAM. Allow even earlier serialization with later
changes.
Also: Switch some SkTDArrays to SkTArrays.

Note to reviewers: Start with changes to SkPDFTypes.h
Many places that had a bare pointer owning a reference are refactored to
use a sk_sp.
There remain several places where a non-owning pointer `T*` should be
replaced with `const sk_sp<T>&` to eliminate the common pattern
`sk_sp<T>(SkRef(x))`.

drawImage calls now properly embeds the original jpeg.
NOTE: drawBitmap*() calls no longer embed JPEG files when
possible (this is in advance of eliminating bitmaps backed
by encoded data). Chromium has already moved from
drawBitmap to drawImage.
Comparisons:
control:
total PDF drawImage/drawBitmap calls: 8010
total PDF jpeg images: 0
total PDF regular images: 3581
experiament:
total PDF drawImage/drawBitmap calls: 8014
total PDF jpeg images: 271
total PDF regular images: 3311
total PDF regular images: 3582 (271 + 3311)
When comparing rendered output there were perceptual
differences in the following four GMs: colorcube, emboss,
colormatrix, and tablecolorfilter. All of these differences
were improvements (that is, closer to the 8888 rendering)
due fixing a bug with colorfilters and forgetting to call
notifyPixelsChanged.
No SKPs had perceptual differences.
Total PDF size dropped from 133964 kB to 126276 kB, a 5.7%
improvement (mostly due to restoring use of JPG images in
SKPs).

It's been outclassed by Valgrind and leak sanitizer,
and it seems to be causing problems for external folks building Skia.
I'm not sure why our own builds seem unaffected.

The Google style guide states that only one of {virtual,override,final}

final implies both virtual and override.
The entries were found using the following command line:

Motivation: Keep separate features separate. Also, future
linearization work will need to have several objNumMap
objects share a substituteMap. Also "catalog" has a
specific meaning in PDF. This catalog did not map to that
catalog.
- Modify SkPDFObject::emitObject and SkPDFObject::addResources
interface to requiore SkPDFObjNumMap and SkPDFSubstituteMap.
- SkPDFObjNumMap const in SkPDFObject::emitObject.
- Remove SkPDFCatalog.cpp/.h
- Modify SkDocument_PDF.cpp to use new functions
- Fold in SkPDFStream::populate
- Fold in SkPDFBitmap::emitDict
- Move SkPDFObjNumMap and SkPDFSubstituteMap to SkPDFTypes.h
- Note (via assert) that SkPDFArray & SkPDFDict don't need to
check substitutes.
- Remove extra space from SkPDFDict serialization.
- SkPDFBitmap SkPDFType0Font SkPDFGraphicState SkPDFStream
updated to new interface.
- PDFPrimitivesTest updated for new interface.

Prior to this change, SkPDFObject subclasses were required
to track their resources separately from the document
structure. (An object has a resource if it depends, via an
indirect reference, on another object). This led to a lot
of extra code to duplicate effort. I replace the
getResources() function with the much simpler addResources()
function. I only define a non-trivial addResources() method
on arrays, dictionaries, and indirect object references.
All other specialized classes simply rely on their parent
class's implementation.
SkPDFObject::addResources() works by recursively walking the
directed graph of object (direct and indirect) references
and adding resources to a set. It doesn't matter that there
are closed loops in the graph, since we check the set before
walking down a branch.
- Add SkPDFObject::addResources() virtual function, with
four implementations
- Remove SkPDFObject::getResources() virtual function and
all implementations.
- Remove SkPDFObject::GetResourcesHelper()
- Remove SkPDFObject::AddResourceHelper()
- In SkPDFCatalog::findObjectIndex(), add an object to the
catalog if it doesn't exist yet.
- SkPDFCatalog::setSubstitute() no longer sets up resources
- SkPDFDocument.cpp no longer needs the Streamer object
- SkPDFDocument.cpp calls fDocCatalog->addResources to build
the resource list.
- SkPDFFont::addResource() removed
- All SkPDF-::fResource sets removed (they are redundant).
- removed SkPDFImage::addSMask() function
- SkPDFResourceDict::getReferencedResources() removed.
Motivation: this removes quite a bit of code and makes the
objects slightly slimmer in memory. Most importantly, this
will lead the way towards removing SkPDFObject's inheritance
from SkRefCnt, which will greatly simplify everything.
Testing: I usually test changes to the PDF backend by
comparing checksums of PDF files rendered from GMs and SKPs
before and after the change. This change both re-orders and
re-numbers the indirect PDF objects. I used the qpdf
program to normalize the PDFs and then compared the
normalized outputs from before and after the change; they
matched.

This adds sk_memory_barrier(), implemented using sk_atomic_fetch_add() on an uninitialized variable. If that becomes a problem we can drop this to the porting layer, using std::atomic_thread_fence() / __atomic_thread_fence() / __sync_synchronize().
The big win is that ref() doesn't generate a memory barrier any more on ARM.
This is an instance of SkSafeRef() in SkPaint(const SkPaint&) after this CL:
4d0: 684a ldr r2, [r1, #4]
4d2: 6018 str r0, [r3, #0]
4d4: b13a cbz r2, 4e6 <_ZN7SkPaintC1ERKS_+0x2e>

4e2: 2d00 cmp r5, #0
4e4: d1f8 bne.n 4d8 <_ZN7SkPaintC1ERKS_+0x20>
Here's the before, pretty much the same with two memory barriers surrounding the ref():
4d8: 684a ldr r2, [r1, #4]
4da: 6018 str r0, [r3, #0]
4dc: b15a cbz r2, 4f6 <_ZN7SkPaintC1ERKS_+0x3e>

The miscellaneous files in here are just fixups to explicitly include SkMutex.h,
instead of leeching it off SkRefCnt.h.
No public API changes.

Replace virutal SkPDFObject::emitObject(s, c, true) with non-virtual
SkPDFObject::emitIndirectObject(s, c), since none of the subclasses do
(or should do) anything different.
Replace object->emitObject(s, c, false) with object->emitObject(s, c)
This is one step in simplifying the SkPDFObject interface to allow for
the next step in refactoring.

Add mutex lock to all functions. Remove dictionary iterator, and
replace with new thread-safe functions.

added capability to collect minidump and callstack if buildbot fails with heap
coruption in windows, and a NPE bug was fixed in SkPDFDocument, when document was destroyed without ever beeing used and a field was NULL + a few minor conflicts have been resolved)

This change creates const and non-const versions of SkTDArray::begin(), end(), operator[]() and getAt(). This will keep us from inadvertently changing a const SkTDArray, which the previous signatures allowed.

The problem fixed - http://code.google.com/p/skia/issues/detail?id=940 - is that getResources will recursively obtain all child resource recursively without checking for duplicates.
If we have lots of duplicates, then we try to build a very large vector (exponential with the number of nodes usually) and sooner or later we end up using too much memory and crash.
A possible solution could have been to make sure resources do not have duplicates, but that requirement is impractical, and it this leaves the solution fragile, if there is any issue in the tree, we crash.
When we emit the pdf, the large number of duplicates is not an issue, because SkPDFCatalog::addObject will deal with duplicates.
I have run the gm with --config pdf, and the images are 100% same bits, while the pdfs have the same size but some very small changes, the order of some objects.
