Seungha Yang de749fa356 cuda: Introduce GST_CUDA_CRITICAL_ERRORS env to abort on critical error
Adding GST_CUDA_CRITICAL_ERRORS env variable so that program can be
terminated on unrecoverable error.

Example)
GST_CUDA_CRITICAL_ERRORS=2,700 gst-launch-1.0 ...

In this example, CUDA_ERROR_OUT_OF_MEMORY(2) and
CUDA_ERROR_ILLEGAL_ADDRESS(700) are registered as critical error
and program will be aborted on those errors
