vl: Fix broken thread=xxx option of the --accel parameter
Commit bde4d9205 ("Fix the -accel parameter and the documentation for
'hax'") introduced a regression by adding a new local accel_opts
variable which shadows the variable with the same name that is
declared at the beginning of the main() scope. This causes the
qemu_tcg_configure() call later to be always called with NULL, so
that the thread=xxx option gets ignored. Fix it by removing the
local accel_opts variable and use "opts" instead, which is meant
for storing temporary QemuOpts values.
And while we're at it, also change the exit(1) here to exit(0)
since asking for help is not an error.

nbd: Fix regression on resiliency to port scan
Back in qemu 2.5, qemu-nbd was immune to port probes (a transient
server would not quit, regardless of how many probe connections
came and went, until a connection actually negotiated). But we
broke that in commit ee7d7aa when removing the return value to
nbd_client_new(), although that patch also introduced a bug causing
an assertion failure on a client that fails negotiation. We then
made it worse during refactoring in commit 1a6245a (a segfault
before we could even assert); the (masked) assertion was cleaned
up in d3780c2 (still in 2.6), and just recently we finally fixed
the segfault ("nbd: Fully intialize client in case of failed
negotiation"). But that still means that ever since we added
TLS support to qemu-nbd, we have been vulnerable to an ill-timed
port-scan being able to cause a denial of service by taking down
qemu-nbd before a real client has a chance to connect.
Since negotiation is now handled asynchronously via coroutines,
we no longer have a synchronous point of return by re-adding a
return value to nbd_client_new(). So this patch instead wires
things up to pass the negotiation status through the close_fn
callback function.
Simple test across two terminals:
$ qemu-nbd -f raw -p 30001 file
$ nmap 127.0.0.1 -p 30001 && \
qemu-io -c 'r 0 512' -f raw nbd://localhost:30001
Note that this patch does not change what constitutes successful
negotiation (thus, a client must enter transmission phase before
that client can be considered as a reason to terminate the server
when the connection ends). Perhaps we may want to tweak things
in a later patch to also treat a client that uses NBD_OPT_ABORT
as being a 'successful' negotiation (the client correctly talked
the NBD protocol, and informed us it was not going to use our
export after all), but that's a discussion for another day.

Log Message:
-----------
qemu-nbd: Ignore SIGPIPE
qemu proper has done so for 13 years
(8a7ddc38a60648257dc0645ab4a05b33d6040063), qemu-img and qemu-io have
done so for four years (526eda14a68d5b3596be715505289b541288ef2a).
Ignoring this signal is especially important in qemu-nbd because
otherwise a client can easily take down the qemu-nbd server by dropping
the connection when the server wants to send something, for example:
$ qemu-nbd -x foo -f raw -t null-co:// &
[1] 12726
$ qemu-io -c quit nbd://localhost/bar
can't open device nbd://localhost/bar: No export with name 'bar' available
[1] + 12726 broken pipe qemu-nbd -x foo -f raw -t null-co://
In this case, the client sends an NBD_OPT_ABORT and closes the
connection (because it is not required to wait for a reply), but the
server replies with an NBD_REP_ACK (because it is required to reply).

nbd: rename read_sync and friends
Rename
nbd_wr_syncv -> nbd_rwv
read_sync -> nbd_read
read_sync_eof -> nbd_read_eof
write_sync -> nbd_write
drop_sync -> nbd_drop
1. nbd_ prefix
read_sync and write_sync are already shared, so it is good to have a
namespace prefix. drop_sync will be shared, and read_sync_eof is
related to read_sync, so let's rename them all.
2. _sync suffix
_sync is related to the fact that nbd_wr_syncv doesn't return if a
write to socket returns EAGAIN. The first implementation of
nbd_wr_syncv (was wr_sync in 7a5ca8648b) just loops while getting
EAGAIN, the current implementation yields in this case.
Why we want to get rid of it:
- it is normal for r/w functions to be synchronous, so having an
additional suffix for it looks redundant (contrariwise, we have
_aio suffix for async functions)
- _sync suffix in block layer is used when function does flush (so
using it for other thing is confusing a bit)
- keep function names short after adding nbd_ prefix
3. for nbd_wr_syncv let's use more common notation 'rw'

nbd/server: get rid of nbd_negotiate_read and friends
Functions nbd_negotiate_{read,write,drop_sync} were introduced in
1a6245a5b, when nbd_rwv (was nbd_wr_sync) was working through
qemu_co_sendv_recvv (the path is nbd_wr_sync -> qemu_co_{recv/send} ->
qemu_co_send_recv -> qemu_co_sendv_recvv), which just yields, without
setting any handlers. But starting from ff82911cd nbd_rwv (was
nbd_wr_syncv) works through qio_channel_yield() which sets handlers, so
watchers are redundant in nbd_negotiate_{read,write,drop_sync}, then,
let's just use nbd_{read,write,drop} functions.
Functions nbd_{read,write,drop} has errp parameter, which is unused in
this patch. This will be fixed later.

vhost-user-scsi: Introduce vhost-user-scsi host device
This commit introduces a vhost-user device for SCSI. This is based
on the existing vhost-scsi implementation, but done over vhost-user
instead. It also uses a chardev to connect to the backend. Unlike
vhost-scsi (today), VMs using vhost-user-scsi can be live migrated.
To use it, start Qemu with a command line equivalent to:
qemu-system-x86_64 \
-chardev socket,id=vus0,path=/tmp/vus.sock \
-device vhost-user-scsi-pci,chardev=vus0,bus=pci.0,addr=...
A separate commit presents a sample application linked with libiscsi to
provide a backend for vhost-user-scsi.

vhost-user-scsi: Introduce a vhost-user-scsi sample application
This commit introduces a vhost-user-scsi backend sample application. It
must be linked with libiscsi and libvhost-user.
To use it, compile with:
$ make vhost-user-scsi
And run as follows:
$ ./vhost-user-scsi -u vus.sock -i iscsi://uri_to_target/
$ qemu-system-x86_64 --enable-kvm -m 512 \
-object memory-backend-file,id=mem,size=512m,share=on,mem-path=guestmem \
-numa node,memdev=mem \
-chardev socket,id=vhost-user-scsi,path=vus.sock \
-device vhost-user-scsi-pci,chardev=vhost-user-scsi \
The application is currently limited at one LUN only and it processes
requests synchronously (therefore only achieving QD1). The purpose of
the code is to show how a backend can be implemented and to test the
vhost-user-scsi Qemu implementation.
If a different instance of this vhost-user-scsi application is executed
at a remote host, a VM can be live migrated to such a host.
