cuFile calls were scattered directly in aiori-POSIX.c. Move them into two layers: - gpu_runtime.h / cuda_runtime.c: wraps cudaMalloc, cudaFree, etc. - gpu_io.h / gpu_io_cufile.c: wraps cuFile driver, register, read/write aiori-POSIX.c now calls only gpu_io_* / gpu_runtime_*. configure.ac: --with-cuda=PREFIX and --with-cufile=PREFIX with proper save/restore. --with-gpu-direct-backend=cufile|none replaces --with-gpuDirect (kept as alias). HAVE_GPU = HAVE_CUDA for now. No behaviour change.

cuFile calls were inlined directly in aiori-POSIX.c. Split them out:
cuFileRead/Write with error decoding
configure.ac:
(old flag still works as alias)
No behaviour change.
