Add infrastructure for doing compatibility shims, as has been sorely needed for the last 10 years. Far too much of the internal API is exposed, and every small adjustment causes applications to stop working. To kick this off, bump the API version to 0x17 as should have been done with r246713, but add shims to compensate. Thanks to the shims, there should be no visible change in application behavior. I have plans to do a significant overhaul of the API to harnen it for the future, but until then, I welcome others to add shims for older versions of the API. Obtained from: Netflix

Widen lun_id_t to 64 bits. This is a follow-on to r257345 to let the kernel support all valid SAM-5 LUN IDs. CAM_VERSION is bumped, as the CAM ABI (though not API) is changed. No behavior is changed relative to r257345 except that LUNs with non-zero high 32 bits will no longer be ignored during device enumeration for SIMs that have set PIM_EXTLUNS. Reviewed by: scottl

Widen lun_id_t to 64 bits. This is a follow-on to r257345 to let the kernel support all valid SAM-5 LUN IDs. CAM_VERSION is bumped, as the CAM ABI (though not API) is changed. No behavior is changed relative to r257345 except that LUNs with non-zero high 32 bits will no longer be ignored during device enumeration for SIMs that have set PIM_EXTLUNS. Reviewed by: scottl
