These patches implement a modification of the USBTMC
protocol to allow operation with Rigol equipment. The usbtmc_read function is
modified so if the quirk is active, the TMC header is sent with the size of
the data as the whole size of the request. If the quirk is inactive, the TMC
request is sent once per bulk transfer and with size limited to the bulk
transfer size. In the case of the quirk, only the first response contains the
TMC header and the others are just data.

These patches implement a modification of the USBTMC
protocol to allow operation with Rigol equipment. The TMC request portion of
the code in function usbtmc_read is segregated to a function
send_request_dev_dep_msg_in as implemented by tommie in
https://github.com/tommie/linux/blob/usbtmc-rigol/drivers/usb/class/usbtmc.c
allowing the reuse later.

These patches implement a modification of the USBTMC
protocol to allow operation with Rigol equipment. Rigol requires that a
single TMC request to receive any buffer size and bulk requests to get the
data. The original algorithm sends a TMC request for each subset of the data
(a single USB transaction). The modification is only active for Rigol
equipment, vendor and product set is contained in the array usbtmc_id_quirk.

This patch creates the rigol_quirk variable and the arrays for the
idvendor and idproduct.

These enums have been separate since the dawn of SAS, mainly because the
latter is a procotol only enum and the former includes additional state
for libsas.  The dichotomy causes endless confusion about which one you
should use where and leads to pointless warnings like this:

drivers/scsi/mvsas/mv_sas.c: In function 'mvs_update_phyinfo':
drivers/scsi/mvsas/mv_sas.c:1162:34: warning: comparison between 'enum sas_device_type' and 'enum sas_dev_type' [-Wenum-compare]

Fix by eliminating one of them.  The one kept is effectively the sas.h
one, but call it sas_device_type and make sure the enums are all
properly namespaced with the SAS_ prefix.
