The Android EGL shim injects GL_EXT_debug_marker into the ES driver EXTENSIONS string for the OpenGL ES 1.x and 2.0/3.0/3.1 drivers if the extension is not already provided. This feature is used by GLES_trace. In Open GL ES 3.0 it became possible to query an indexed version of the EXTENSIONS string via GetStringi(). NUM_EXTENSIONS Gets were also added to the specification (taken from Open GL). If the shim does not have to inject the extension, then there is no problem, as glGetString() and glGetStringi() / NUM_EXTENSIONS will be consistent. However, if the Android EGL shim injects the extension, NUM_EXTENSIONS and GetStringi() will report one less extension than is really available. Consistency between these methods is tested by the dEQP framework with the dEQP-GLES3.functional.state_query.string.extensions test. If the driver does not provide GL_EXT_debug_marker, this test fails. This change wraps all of the affected entry points so that the wrapped driver extensions are never visible directly to dEQP, eliminating the inconsistency.
