Thus far, the client end of the socket is the only piece of client state
tracked in tests, for which a global `socket` variable has been used. In
preparation to add more state, replace the `socket` global with a
`client` global object that groups all client state.

Harmonize and rename the vfu_*sg() APIs to better reflect their functionality:
in our case, there is no mapping happening as part of these calls, they are
merely housekeeping for range splitting, dirty tracking, and so on.

We explicitly identify the quiesce EBUSY case for msg(), letting us simplify the
handling of expected errno.

Aside from general style goodness, this found a couple of accidental
re-definitions, so it's worth taking the pain now.
Also, only run rstlint as part of pre-push.

Most tests need to send a request, process it, then retrieve the reply.
Add a utility function to avoid lots of tedious boilerplate.

Since the dirty bitmap in message replies is allocated based upon the maximum
size of an individual region, add a limit (somewhat arbitrarily 8TiB, which is a
bitmap size of 256MiB). Add a couple of basic tests on the two DMA limits.
