We intentionally renamed 'debug-level' to 'debug' in the QMP
schema for 'blockdev-add' related to gluster, in order to
match the command line (commit 1a417e46). However, since
'debug-level' was visible in 2.7, that means that we should
document that 'debug' was not available until 2.8.
The change was intentional because 'blockdev-add' itself
underwent incompatible changes (such as commit 0153d2f) for
the same release; our intent is that after 2.8, these
interfaces will now be stable. [In hindsight, we should have
used the name x-blockdev-add when we first introduced it]

The qobject_from_jsonf() function implements a pseudo-printf
language for creating a QObject; however, it is hard-coded to
only parse a subset of formats understood by -Wformat, and is
not a straight synonym to bare printf(). In particular, any
use of an int64_t integer works only if the system's
definition of PRId64 matches what the parser expects; which
works on glibc (%lld or %ld depending on 32- vs. 64-bit) and
mingw (%I64d), but not on Mac OS (%qd). Rather than enhance
the parser, it is just as easy to use 'long long', which we
know always works. There are few enough callers of
qobject_from_json[fv]() that it is easy to audit that this is
the only non-testsuite caller that was actually relying on
this particular conversion.

Signed-off-by: Markus Armbruster <armbru@redhat.com>
Because TFTP does not support byte ranges, it was never usable with our
curl block driver. Since apparently nobody has ever complained loudly
enough for someone to take care of the issue until now, it seems
reasonable to assume that nobody has ever actually used it.
Therefore, it should be safe to just drop it from curl's protocol list.
[Jeff Cody: Below is additional summary pulled, with some rewording,
from followup emails between Max and Markus, to explain what
worked and what didn't]
TFTP would sometimes work, to a limited extent, for images <= the curl
"readahead" size, so long as reads started at offset zero. By default,
that readahead size is 256KB.
Reads starting at a non-zero offset would also have returned data from a
zero offset. It can become more complicated still, with mixed reads at
zero offset and non-zero offsets, due to data buffering.
In short, TFTP could only have worked before in very specific scenarios
with unrealistic expectations and constraints.

Event generation has to be moved from bdrv_eject() to the BlockBackend

The option whether or not to use a native AIO interface really isn't a
generic option for all drivers, but only applies to the native file
protocols. This patch moves the option in blockdev-add to the
appropriate places (raw-posix and raw-win32).
We still have to keep the flag BDRV_O_NATIVE_AIO for compatibility
because so far the AIO option was usually specified on the wrong layer
(the top-level format driver, which didn't even look at it) and then
inherited by the protocol driver (where it was actually used). We can't
forbid this use except in new interfaces.
