IInputContext is the IPC interface name used behind InputConnection,
which was named in the initial development of IME API for Android 1.5.
To make it more descriptive and consistent with other classes such as
RemoteInputConnection, let's rename it to IRemoteInputConnection.
This CL also renames
IInputContextInvoker
to
IRemoteInputConnectionInvoker
for consistency.
This is a rename of internal IPC interface. There should be no
user/developer observable impact.
