v2: Instead of releasing the UBO's at the end don't reference count them.
The guest keeps track of these resources and their reference counts,
so it will not release the UBO's without re-setting the binding during
the live time of a client progra, However, at final clean up the UBO's
are not rebound before the resourse is released in the guest side resulting
in the memory leak. When we skip the ref-counting on the host side the
resourses are cleaned up correctly without breaking the program otherwise.
Fixes resource leaks:
Direct leak of 2448 byte(s) in 9 object(s) allocated from:

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.

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.
