Klaus Kämpf 28a43b3390 Honor sector size change via ModeSelect6 in scsicd (#1406)
* Make ModeSelect() non-const

Signed-off-by: Klaus Kämpf <kkaempf@gmail.com>

* Implement ModeSelect for scsicd

and honor sector size setting.

DEC's VMS can't handle 2k sector sizes and uses ModeSelect6 to set the
sector size to 512 bytes.

Fixes #1397

* resize cache after change of sector size

The disk cache is based on sector size and must be resized when the
sector size changes.

Disk::ResizeCache needs a `raw` parameter, make this value accessible
from the current cache.
