directly, rather than calling the vfs macro. This behaviour may cause
issues for VFS modules that delegate fs_capabilities handling to

macOS client overload this after negotiating AAPL via their SMB2
extensions, meaning it's a so called copyfile request (copy whole file
and all streams).

We previously checked this at the SMB layer, with this patch we just
send this down the VFS, if vfs_fruit is loaded it implements the macOS
copyile semantics, otherwise we get Windows behavour..

af6cbc7a44 s3/vfs: add SMB_VFS_OFFLOAD_READ_SEND/RECV
Add SMB_VFS_OFFLOAD_READ_SEND an SMB_VFS_OFFLOAD_READ_RECV.

This paves the way for supporting server-side copy-chunk with source and
destination file-handles on different shares. It can be used to
implement copy offload fsctl in the future, but for now this will be
used as a mere copy-chunk replacement.

SMB_VFS_OFFLOAD_READ generates a token that associates an fsp with the
token and stores the fsp in a in-memory db.

Initially only a copy-chunk resume key fsctl is supported. In the future
this can be enhanced to support real offload fsctl.
