Mark all SYSCTL_NODEs static that have no corresponding SYSCTL_DECLs.

The SYSCTL_NODE macro defines a list that stores all child-elements of
that node. If there's no SYSCTL_DECL macro anywhere else, there's no
reason why it shouldn't be static.

- Export more USB device ID's.

Remove unneeded includes of <sys/linker_set.h>. Other headers that use
it internally contain nested includes.

- FIFO's are always opened separately in read and write
direction even if the actual device is opened for read and
write. Fix fflags check so that the UFM and URIO drivers work.

Purge mergeinfo from files that were temporarily renamed while USB2 was
imported into the tree alongside USB.

Approved by: re (mergeinfo blanket)

- Make struct usb_xfer opaque so that drivers can not access the internals
- Reduce the number of headers needed for a usb driver, the common case is just usb.h and usbdi.h

- make usb2_power_mask_t 16-bit
- remove "usb2_config_sub" structure from "usb2_config". To compensate for this
"usb2_config" has a new field called "usb_mode" which select for which mode
the current xfer entry is active. Options are: a) Device mode only b) Host
mode only (default-by-zero) c) Both modes. This change was scripted using
the following sed script: "s/\.mh\././g".
- the standard packet size table in "usb_transfer.c" is now a function, hence
the code for the function uses less memory than the table itself.

Rename the ushub device class back to uhub as it was in the old usb stack,
moused(8) looks for "uhub/ums" to decide if needs to load the module.

Change USB over to make_dev() for all device nodes, previously it hooked into
the devfs clone handler to open the (invisible) devices on the fly.

The /dev entries are layed out as follows,

/dev/usbctl = master device
/dev/usb/0.1.0.5 = usb device, (<bus>.<dev>.<iface>.<endpoint>)
/dev/ugen0.1 -> usb/0.1.0.0 = ugen link to ctrl endpoint

This also removes the custom permissions model from USB. Bump
__FreeBSD_version to 800066.
