We need to pass the NBT header, SMB2 header and SMB2 Read header
as header blob to SMB_VFS_SENDFILE(). This allows the usage
of MSG_SEND or other tricks to avoid multiple TCP packets

Going via tevent_req_create/talloc_free at multiple layer costs
too much cpu cycles per request.
I tested downloading a 16GB (sparse) file with smbclient -b1 -mNT1,
and -mSMB2_02. Using smb2 max read = 64512, which means smb1 and smb2
will use the same read size.
I build with -O3 -g and compared the results with valgrind --tool=callgrind.
With -mNT1 the server uses about 2.000.000.000 cpu cycles.
This patch reduces the userspace cpu cycles for -mSMB2_02
from about ~ 8.000.000.000 down to ~ 4.000.000.000.

If we msg_read_send on a nonempty channel, we create one
tevent_immediate. If we directly receive another message and from
within the msg_read_send's tevent_req callback we immediately do
another msg_read_send, we end up with two tevent_immediate events for
msg_channel_trigger with just one incoming message. Test to follow.
This patch simplifies msg_channel.c by removing the explicit immediate
events. Instead, it relies on the implicit immediate event available
via tevent_req_defer_callback. For messages received from tdb with
a msg_read_send req pending, we directly finish that request without
putting the message on the queue.

This is a performance improvement for heavily contended files, in
particular in a cluster. The separate call to get_file_infos makes us
pull the locking.tdb record twice per open. For a contended file this
can be a performance penalty, this gets the # of record accesses for
the open/close cycle down from 3 to 2.

The VFS interfaces are sychronous, as the operations only modify
meta-data.
These hooks are dependent on support for transparent compression by the
underlying filesystem - vfs_default returns INVALID_DEVICE_REQUEST.
Support for other filesystems providing transparent comression, such as
Btrfs and ZFS, can be added in future.
The get_compression function takes fsp and smb_fname arguments. The
smb_fname argument is needed due to the current dosmode() code-path.
