sym(4): Use memcpy(9) instead of bcopy(9)
The overlap handling of bcopy(9) is not required in these cases.

sym(4): Provide a DEVICE_DETACH(9) method
This also fixes sym_cam_free() to tear things down correctly, i. e. in
opposite order of setup, as well as sym_cam_attach() to not free devq
and SIM twice in the failure case.

sym(4): Map HCB memory as uncacheable also on x86
As part of making the chip-specific mix and match of different accesses
(DMA/bus space) work as desired, the intent is to map the HCB memory as
uncacheable. Prior to VM_MEMATTR_*, the !x86 way of indicating this to
bus_dmamem_alloc(9) was BUS_DMA_COHERENT. Then later on in 2db99100a4,
BUS_DMA_NOCACHE was hooked up to VM_MEMATTR_UNCACHEABLE for x86. As it
turns out, still as of today bus_dmamem_alloc(9) differs in this regard
across architectures. On arm, it still supports BUS_DMA_COHERENT only
for requesting uncacheable DMA and x86 still uses BUS_DMA_NOCACHE only.
On arm64 and riscv, BUS_DMA_COHERENT seems to effectively be an alias
for BUS_DMA_NOCACHE.
Thus, allocate the HCB memory with BUS_DMA_COHERENT | BUS_DMA_NOCACHE,
so we get uncacheable memory on all architectures including x86 and so
loads and stores from/to HCB won't get reordered. However, even on x86
we still need to use at least compiler barriers to achieve the desired
program order.

nfscl: Fix handling of case insensitive file systems
Name caching must be handled somewhat differently
for case insensitive file systems. Negative name
caching does not work and, for rename, all names
associated with the rename'd vnode must be disabled.
For a case insensitive ZFS file system that is exported,
the unpatched code did work, since the change in mtime
or ctime of the directory when other case names were
created or rename'd would disable the false name cache
hit. However, an export of an msdosfs file system
breaks the NFS client, because it only works if ctime/mtime
is changed whenever a name is added/removed. Depending
on what the server file system is, this may not happen,
due to clock resolution or lack of support for these
attributes.
This patch checks to see if the server file system is

nfsd: Fix handling of attributes during Open/Create/Exclusive_41
When an NFSv4.n client specifies settings for attributes other
mode during a Open/Create/Exclusive_41, these other attributes
were not being set.
This patch resolves the problem by calling nfsrv_fixsattr()
after the VOP_CREATE() call in nfsvno_open() for this case.
There is no extant NFSv4.n client that currently does this,
as far as I know.
