Niklas Haas	67adb30322	swscale: rename SwsContext to SwsInternal And preserve the public SwsContext as separate name. The motivation here is that I want to turn SwsContext into a public struct, while keeping the internal implementation hidden. Additionally, I also want to be able to use multiple internal implementations, e.g. for GPU devices. This commit does not include any functional changes. For the most part, it is a simple rename. The only complications arise from the public facing API functions, which preserve their current type (and hence require an additional unwrapping step internally), and the checkasm test framework, which directly accesses SwsInternal. For consistency, the affected functions that need to maintain a distionction have generally been changed to refer to the SwsContext as sws, and the SwsInternal as c. In an upcoming commit, I will provide a backing definition for the public SwsContext, and update `sws_internal()` to dereference the internal struct instead of merely casting it.

swscale: rename SwsContext to SwsInternal

And preserve the public SwsContext as separate name. The motivation here
is that I want to turn SwsContext into a public struct, while keeping the
internal implementation hidden. Additionally, I also want to be able to
use multiple internal implementations, e.g. for GPU devices.

This commit does not include any functional changes. For the most part, it is
a simple rename. The only complications arise from the public facing API
functions, which preserve their current type (and hence require an additional
unwrapping step internally), and the checkasm test framework, which directly
accesses SwsInternal.

For consistency, the affected functions that need to maintain a distionction
have generally been changed to refer to the SwsContext as *sws, and the
SwsInternal as *c.

In an upcoming commit, I will provide a backing definition for the public
SwsContext, and update `sws_internal()` to dereference the internal struct
instead of merely casting it.
