The intended functionality of QMP `cpu-add` is replaced with
`device_add` (and `query-hotpluggable-cpus`). So let's deprecate
`cpu-add`.
A complete example of vCPU hotplug with the recommended way (using
`device_add`) is provided as part of a seperate docs patch.

POSIX states that the value of endptr is unspecified if strtol()
fails with EINVAL due to an invalid base argument. Since none of
the callers to check_strtox_error() initialized endptr, we could
end up propagating uninitialized data back to a caller on error.
However, passing an out-of-range base is already a sign of poor
programming, so let's just assert that base is in range, at which
point check_strtox_error() can be tightened to assert that it is
receiving an initialized ep that points somewhere within the
caller's original string, regardless of whether strto*() succeeded
or failed with ERANGE.

While most developers are now using UTF-8 environments, it's
harder to guarantee that error messages will be output to
a multibyte locale. Rather than risking error messages that
get corrupted into mojibake when the user runs qemu in a
non-multibyte locale, let's stick to straight ASCII error
messages, rather than assuming that our use of UTF-8 in source
code string constants will work unchanged in other locales.

Adding a new qapi module had some rather tedious repetition to
wire it into Makefile, Makefile.objs, and .gitignore (for example,
see commit bf42508f and its followup b61acdec). For make, add some
indirection by taking advantage of GNU Make string processing to
expand a list of module names into all the required artifacts, so
that future additions of a new module need only touch the list of
module names. And for gitignore, use globs to cover all generated
file names.
The list has to live in Makefile.objs, due to the way that
our unnest-vars macro slirps in that file without remembering
any definition of $(QAPI_MODULES) from Makefile.

The token field contains the (guest-filled) state of the qtd, which
indicates whenever the other fields are valid or not. So make sure
we read the token first, otherwise we may end up with an stale next
pointer:
(1) ehci reads next
(2) guest writes next
(3) guest writes token
(4) ehci reads token
(5) ehci operates with stale next.
Typical effect is that qemu doesn't notice that the guest appends new
qtds to the end of the queue. Looks like the usb device stopped
responding. Linux can recover from that, but leaves a message in the
kernel log that it did reset the usb device in question.

Check 'smb_index' value to avoid OOB access.
Note that this bug is exploitable by a guest to escape
from the virtual machine. However the commit which
introduced the bug was only made after the 3.0 release,
and so it is not present in any released QEMU versions.
