manage a set of power-of-2 sized buffers for bus_dmamem_alloc().
This allows the caller to provide the back-end allocator uma allocator,
allowing full control of the memory pages backing the pool. For
convenience, it provides an optional builtin allocator that provides pages
allocated with the VM_MEMATTR_UNCACHEABLE attribute, for managing pools of
DMA buffers for BUS_DMA_COHERENT or BUS_DMA_NOCACHE.
This also allows the caller to specify a minimum alignment, and it ensures
that all buffers start on a boundary and have a length that's a multiple of
that value, to avoid using buffers that trigger partial cache line flushes.

Starting with firmware v7.5, the "Read TouchPad Modes" ($01) and "Read
Capabilities" ($02) commands changed: previously constant bytes now
carry variable information.
We now compare those bytes to expected constants only for firmware prior
to v7.5.

caused by use of an invalid kgss_gssd_handle during an upcall to
the gssd daemon when it has exited. This patch seems to avoid the
crashes by holding a reference count on the kgss_gssd_handle until
the upcall is done. It also adds a new mutex kgss_gssd_lock used to
make manipulation of kgss_gssd_handle SMP safe.

LUNs for the virtual processor device. This removes lots of CAM warnings,
and follows similar recent changes to tws(4) and twa(4) drivers.
Also fix case where CAM_REQ_CMP was getting OR'd with CAM_DEV_NOT_THERE
in the nonexistent LUN case, resulting in different CAM status (CAM_UA_TERMIO)
getting reported to CAM. This issue existing previously, but was more subtle
because it changed CAM_SEL_TIMEOUT to CAM_CMD_TIMEOUT.
