af14759181 vhost: introduce API to start a specific driver
We used to use rte_vhost_driver_session_start() to trigger the vhost-user
session. It takes no argument, thus it's a global trigger. And it could
be problematic.

The issue is, currently, rte_vhost_driver_register(path, flags) actually
tries to put it into the session loop (by fdset_add). However, it needs
a set of APIs to set a vhost-user driver properly:
  * rte_vhost_driver_register(path, flags);
  * rte_vhost_driver_set_features(path, features);
  * rte_vhost_driver_callback_register(path, vhost_device_ops);

If a new vhost-user driver is registered after the trigger (think OVS-DPDK
that could add a port dynamically from cmdline), the current code will
effectively starts the session for the new driver just after the first
API rte_vhost_driver_register() is invoked, leaving later calls taking
no effect at all.

To handle the case properly, this patch introduce a new API,
rte_vhost_driver_start(path), to trigger a specific vhost-user driver.
To do that, the rte_vhost_driver_register(path, flags) is simplified
to create the socket only and let rte_vhost_driver_start(path) to
actually put it into the session loop.

Meanwhile, the rte_vhost_driver_session_start is removed: we could hide
the session thread internally (create the thread if it has not been
created). This would also simplify the application.

NOTE: the API order in prog guide is slightly adjusted for showing the
correct invoke order.

5d8f0baf69 log: do not drop debug logs at compile time
Today, all logs whose level is lower than INFO are dropped at
compile-time. This prevents from enabling debug logs at runtime using
--log-level=8.

The rationale was to remove debug logs from the data path at
compile-time, avoiding a test at run-time.

This patch changes the behavior of RTE_LOG() to avoid the compile-time
optimization, and introduces the RTE_LOG_DP() macro that has the same
behavior than the previous RTE_LOG(), for the rare cases where debug
logs are in the data path.

So it is now possible to enable debug logs at run-time by just
specifying --log-level=8. Some drivers still have special compile-time
options to enable more debug log. Maintainers may consider to
remove/reduce them.

64ab701c3d vhost: add vhost-user client mode
Add a new paramter (flags) to rte_vhost_driver_register(). DPDK
vhost-user acts as client mode when RTE_VHOST_USER_CLIENT flag
is set.  The flags would also allow future extensions without
breaking the API (again).

The rest is straingfoward then: allocate a unix socket, and
bind/listen for server, connect for client.

This extension is for vhost-user only, therefore we simply quit
and report error when any flags are given for vhost-cuse.

e2a1dd1275 vhost: rename device id variable
I failed to figure out what does "fh" mean here for a long while.
The only guess I could have had is "file handle". So, you get the
point that it's not well named.

I then figured it out that "fh" is derived from the fuse lib, and
my above guess is right. However, device_fh represents a virtio
net device ID. Therefore, here I rename it to vid (Virtio-net device
ID, or Vhost device ID; choose one you prefer) to make it easier for
understanding.

This name (vid) then will be considered to the only interface to
applications. That's another reason to do the rename: it's our
interface, make it more understandable.

And since ctx.fh is derived from device_fh, declare it as int, too.

rte_thread_setname was a macro defined only for Linux.
The function rte_thread_setname() can now be used on FreeBSD

It is required to build librte_pdump.

The macro was 0 for old glibc. The function is now returning -1.

it is not an important failure, just a debug inconvenience.

The debug logs must be enabled at compile-time and run-time.
There are also some internal flags in some examples to enable the debug
logs of the applications. They are now enabled in debug configs and
can be disabled thanks to the more generic logtype mechanism:
	rte_set_log_type(RTE_LOGTYPE_USER1, 0);

Removing these #ifdef allows to test these code branches more easily
and avoid dead code pitfalls.
