Fixing SkPicture serialization
Fixed a few issues while attempting to use the new
serialization path for SkPicture inside a fuzzer:
- SkReadBuffer and SkValidatingReadBuffer both had a fReader
member instead of sharing the same member, which leads to
problems if a base class function is used
- In SkPicture, a header is now written as a single chunk of
data, so it also has to be read as a single chunk of data
- In the SkPicturePlayback destructor, a bad deserialization
would lead to a crash if we don't safely unref fOpData
- Also in SkPicturePlayback, if we only use a ReadBuffer for
the whole deserialization, additional tags must be added to
parseBufferTag()
- SkValidatingReadBuffer::readBitmap() was broken, but this
path wasn't usen't since the only use case for
SkValidatingReadBuffer is currently image filters and
bitmaps are unflattened as part of the deserialization of
SkBitmapSource
- SkPictureImageFilter was not deserializable. Added it to
SkGlobalInitialization*
- Added a test that exercises the SkPicture serialization /
deserialization code

Refactor read and write buffers.
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.

Fixed more fuzzer issues
- Added the "isAvailable" function to check how much bytes are remaining in the stream before doing potentially large mallocs. That way, we can signal a bad stream instead of crashing.
- Added data validation in SkImageInfo.cpp
- Added NULL pointer check in displacement
- Modified the fuzzer for randomized bitmap types

Fixed a few places where uninitialized memory could have been read
Also added early exit in SkImageFilter's constructor to avoid attempting to deserialize all inputs once a bad input has been found. This avoids hanging if a filter pretends to have 1 billion inputs when that's just an error on the number of inputs read by the filter.

Adding size parameter to read array functions
In some cases, the allocated array into which the data will be read is using getArrayCount() to allocate itself, which should be safe, but some cases use fixed length arrays or compute the array size before reading, which could overflow if the stream is compromised.
To prevent that from happening, I added a check that will verify that the number of bytes to read will not exceed the capacity of the input buffer argument passed to all the read...Array() functions.
I chose to use the byte array for this initial version, so that "size" represents the same value across all read...Array() functions, but I could also use the element count, if it is preferred.
Note : readPointArray and writePointArray are unused, so I could also remove them
