When changing the from a one-by-one upload to an array upload the test for the
array pointer to the uniform IDs was replaced by testing the uniform array ID
against -1. However, this is not enough, because when the context is allocated
all is cleared to zero, and apparently the structure is re-used in different
invocations of shader programs. Here, one shader might have been removed but
the const field was still allocated resulting in a sigsegv. This happens e.g.
by running
dEQP-GLES31.functional.primitive_bounding_box.wide_points.
global_state.vertex_tessellation_geometry_fragment.fbo_bbox_larger
global_state.vertex_tessellation_geometry_fragment.fbo_bbox_smaller
tessellation_set_per_draw.vertex_tessellation_fragment.default_framebuffer_bbox_equal
tessellation_set_per_draw.vertex_tessellation_fragment.default_framebuffer_bbox_larger
resulting in

The signal is caused by a READ memory access.

The sub-context holds a pointer to the last shader program used and this
is de-referenced , e.g. in vrend_vbo_draw. However, the guest may destroy
the program without notifying the sub-context, and as a result the pointer
becomes stale and may ber used after free.
As a solution add a pointer to the owning context when a program is
referenced and if the program gets destroyed, clean the pointer in the sub-context.
