Leon Scroggins III c8037dc5ed Reland "Hide SkEncodedInfo" 
This partially reverts commit
1793e7bb46.

Hide SkEncodedInfo

Bug: skia:7353
Bug: skia:6839

This contains information that is not necessary for clients to know. The
Color enum tells the number of components in the input, but this is only
interesting internally (to the SkSwizzler).

Similarly, the Alpha enum differs from SkAlphaType in that it has
kBinary instead of kPremul. This is useful information only internally
for determining whether the SkColorSpaceXform needs to premultiply.

The bitsPerComponent is potentially useful for a client; Android (in
SkAndroidCodec) uses it to determine the SkColorType. Rather than
exposing bitsPerComponent, make SkAndroidCodec a friend so it can
access the SkEncodedInfo. A future change will change SkCodec to
recommend F16 for bitsPerComponent > 8, but that will be more involved;
it was the reason for the revert of this CL.

Switch conversionSupported to use an SkColorType, which is enough info.

Replace the SkEncodedInfo::Alpha field on SkCodec::FrameInfo with an
SkAlphaType.

SkCodec still needs an SkEncodedInfo, so move its header (which is
already not SK_API) to include/private.

README 

The third_party directory contains a set of dependencies from outside sources
that are needed to build various components and tools within Skia.  

Some of these dependencies reside within the Skia repo, while others are pulled 
from other repositories and placed in the third_party/externals directory
during build. These external dependencies are defined in a DEPS file.

Products in third_party are subject to their own respective license terms.  The
license for each project should be included in the source itself via a license
header or file.  If the source itself does not include a license header or file,
create a README that refers to reliable documentation of the project's license
terms on the web.
