While accessing a unusual usb storage (ums-alauda, ums-cypress, ...),
the module reference count is not incremented. Because these drivers
allocate scsi hosts with usb_stor_host_template defined in usb-storage
module. So these drivers always can be unloaded.
This fixes it by preparing scsi host template which is initialized
at module_init() for each ums-* driver. In order to minimize the
difference in ums-* drivers, introduce module_usb_stor_driver() helper
macro which is same as module_usb_driver() except that it also
initializes scsi host template.

This patch causes a port reset whenever there's a transport error or abort.
If that fails it reverts back to doing a mass-storage device reset. It
started life as as497 and was rediffed by me.
This makes error recovery a lot quicker and more reliable.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!
