s3: rpc_server/srvsvc: NetShareSetInfo - let CSC policy be settable.

The current code simply denies changing the csc policy through RPC
calls. Change that to allow changing the csc policy and call the 'change
share command' when a SetInfo RPC call changes the setting.

torture: add zero length FSCTL_SRV_COPYCHUNK test

Windows Server 2012 returns NT_STATUS_INVALID_PARAMETER for
FSCTL_SRV_COPYCHUNK requests that include a server-side copy length of
zero, in line with MS-SMB2 3.3.5.15.6.

We should match this behaviour, so test for it.

smbd/smb2_ioctl: fail zero length copy chunk requests

As documented in MS-SMB2 3.3.5.15.6 Handling a Server-Side Data Copy
Request, an invalid parameter response should be sent when:

The Length value in a single chunk is greater than
ServerSideCopyMaxChunkSize or *equal to zero*.

We do not currently abide by the latter part of this clause.

vfs_btrfs: pass-through copy-chunk(len=0) requests

Never map copy-chunk(len=0) requests to BTRFS_IOC_CLONE_RANGE ioctls. A
BTRFS_IOC_CLONE_RANGE with @src_length=0 results in a clone of all data
