We recently improved the log messages in the vhost library, adding some
context that helps filtering for a given vhost-user device.
However, some parts of the code were missed, and some later code changes
broke this new convention (fixes were sent previous to this patch).
Change the VHOST_LOG_CONFIG/DATA helpers and always ask for a string
used as context. This should help limit regressions on this topic.
Most of the time, the context is the vhost-user device socket path.
For the rest when a vhost-user device can not be related, generic
names were chosen:
- "dma", for vhost-user async DMA operations,
- "device", for vhost-user device creation and lookup,
- "thread", for threads management,
