Detailed Description

One mass-storage function: a single instance of the class on a device.

Create one with msc_add(); it stays valid for the life of the device. The fields are maintained by the class and are read-only to the app - they are here so a callback (or a second function sharing the same app state) can tell which disk it is looking at and how it was wired up, without keeping its own table.

It is a distinct type from the other classes' handles, so passing (say) a cdc_port where a msc_disk is wanted is a compile error, not a misread state block.
