Add a function to inspect an SkShader to determine if it is an
SkComposeShader.

Add a virtual function for determining if an SkShader is a custom
shader, which returns a custom set of information. The
implementation is in Android, and this function is only defined
if SK_BUILD_FOR_ANDROID_FRAMEWORK.

As a first step towards removing SkShader::setLocalMatrix, which will make
SkShader thread-safe, remove calls to setLocalMatrix that happen immediately
after the shader is being created. Instead, pass the matrix into the constructor
or factory method.

Eliminates SkFlattenable{Read,Write}Buffer, promoting SkOrdered{Read,Write}Buffer
a step each in the hierarchy.

What used to be this:

SkFlattenableWriteBuffer -> SkOrderedWriteBuffer
SkFlattenableReadBuffer -> SkOrderedReadBuffer
SkFlattenableReadBuffer -> SkValidatingReadBuffer

is now

SkWriteBuffer
SkReadBuffer -> SkValidatingReadBuffer

Benefits:
- code is simpler, names are less wordy
- the generic SkFlattenableFooBuffer code in SkPaint was incorrect; removed
- write buffers are completely devirtualized, important for record speed

This refactoring was mostly mechanical. You aren't going to find anything
interesting in files with less than 10 lines changed.

I think I applied the trick everywhere possible. Limitations:
- can't be used with templated classes
- all constructors and destructors must be defined inline

A couple of the SkAutoFoo were unused in Skia, Chromium, and Android, so I
deleted them. This change caught the same bugs Cary found in SkPath, plus one
more in SampleApp.

Remove the make_debugger script, which was created to force
rebuilding without global static initializers so that all flattenables
would be linked. It is no longer necessary since all flattenables
will be linked thanks to InitializeFlattenables, which now can (and
must) be called when global static initializers are turned on.

1. Make flatten() a protected method as callers should use
SkFlattenableWriteBuffer to flatten an object
2. Make flatten a const method (including subclasses)
3. Mark subclass implementation of flatten with SK_OVERRIDE
4. Ensure overridden flatten impls call their parent
5. Remove no-op implementations of flatten from subclasses

Additionally, if necessary the unflattening constructor was
also moved to the protected section of the subclasses
header if it was not already there.

82065d667f64e232bcde2ad849756a6096fcbe6f 07-Feb-2011 reed@google.com <reed@google.com@2bbb7eff-a529-9590-31e7-b0007b416f81> remove SkRefCnt safeRef() and safeUnref(), and replace the call-sites with
SkSafeRef() and SkSafeUnref().

This is basically a bug waiting to happen. An optimizing compiler can remove
checks for null on "this" if it chooses. However, SkRefCnt::safeRef() relies on
precisely this check...

void SkRefCnt::safeRef() {
if (this) {
this->ref();
}
}

Since a compiler might skip the if-clause, it breaks the intention of this
method, hence its removal.

static inline void SkSafeRef(SkRefCnt* obj) {
if (obj) {
obj->ref();
}
}

This form is not ignored by an optimizing compile, so we use it instead.

call these new procs in (nearly) all the places we had inlined loops before.
In once instance (blitter_argb32::blitAntiH) we get different results by a
tiny bit. The new code is more accurate, and exactly inline with all of the
other like-minded blits, so I think the change is good going forward.
