76da233af1 vfs_default: Fix passing of errno from async calls
Current code assigns errno from async pthreadpool calls to the
vfs_default internal vfswrap_*_state.  The callers of the vfs_*_recv
functions expect the value from errno in vfs_aio_state.error.

Correctly assign errno to vfs_aio_state.error and remove the unused
internal err variable.

378886b89c smbd: Fix a connection run-down race condition
When we do a server exit with active aio jobs, we need to keep the
aio state active for the helper thread. Right now I don't see another
chance than to leak memory in this case. And, I don't really oversee
how cancelling requests works in this case, but this does fix crashes
seen at a customer site.

6f3b421c4a s3/vfs: merge offline functionality into DOS attributes handling
The offline VFS functions predate the SMB_VFS_{GET|SET}_DOS_ATTRIBUTES()
functions, now that we have these, we can use them for the offline
attribute as well.

The primary reason for this is: performance. Merging both functions has
the benefit that in VFS modules that use same backing store bits for
both offline attribute and DOS attributes (like gpfs), we avoid calling
the backing store twice in dos_mode() and file_set_dosmode().

This commit modifies all existing users of the offline attribute to
adapt to the change, the next commit will then remove the obsolete
offline functions.

c11ad90a24 smbd: ignore SVHDX create context
According to discussions with dochelp@microsoft.com, an SMB
server should ignore an SVHDX_OPEN_DEVICE_CONTEXT or
SVHDX_OPEN_DEVICE_CONTEXT_V2 create context if it does not
support the RSVD protocol. This is contrary to [MS-SMB2] rev 48.0
which states (3.3.5.9.14) that the open should fail in this case.

Failing the create fails Windows backup if the SMB dialect is
SMB3.0.2 or higher.

Hopefully a new revision of MS-SMB2 will clear this up in the future.

Meanwhile, this patch modifies smbd to ignore the
SVHDX_OPEN_DEVICE_CONTEXT by default. This can be overriden by a VFS
module if a VFS module adds support for RSVD.
