d9716cb0db s3:smb2_server: propagate NTSTATUS from smb2_sendfile_send_data() to smbd_smb2_flush_send_queue()
Calling exit_server() from within a destructor is a bit ugly...

This will result in smbd_server_connection_terminate() instead of
directly calling exit_server(), which will be useful for multi-channel in
future.

f01af728fe smbd: Use mutex instead of fcntl lock for echohandler coordination
This is based on a patch from Volker. When the system supports roboust
mutexes, they will be used for the coordiations between worker and
echohandler process. This avoids another aspect of the fcntl scalibility
issue when handling many client connections. When mutexes are not
available, the code falls back to the fcntl lock.

4244a2686c s3:smb2_server: for performance reasons we use tevent_fd and readv/writev directly
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.
