Added rcGetGLString token to renderControl to query a GL string constant from the current context from the host. Implement glGetString functinality in EGL so that the string value can be cached in the context structure and also implementation can be shared between GLESv1 and GLESv2. Also, fixed clientAPI context initialization check in eglMakeCurrent. The check was for the previously bounded context instead for the newly bounded context.
