Currently, any captured output (via `capture-output`) is segregated into
separate GuestExecStatus fields (`out-data` and `err-data`). This means
that downstream consumers have no way to reassemble the captured data
back into the original stream.
This is relevant for chatty and semi-interactive (ie. read only) CLI
tools. Such tools may deliberately interleave stdout and stderr for
visual effect. If segregated, the output becomes harder to visually
understand.
This commit adds a new enum variant to the GuestExecCaptureOutputMode
qapi to merge the output streams such that consumers can have a pristine
view of the original command output.

Previously capture-output was an optional boolean flag that either
captured all output or captured none. While this is OK in most cases, it
lacks flexibility for more advanced capture cases, such as wanting to
only capture stdout.
This commits refactors guest-exec qapi to take an enum for capture mode
instead while preserving backwards compatibility.

Most export types install BlockDeviceOps pointers. It is easy to forget
to remove them because that happens automatically via the "drive" qdev
property in hw/ but not block/export/.
Put blk_set_dev_ops(blk, NULL, NULL) calls in the core export.c code so
the export types don't need to remember.
This fixes the nbd and vhost-user-blk export types.

Some time after systemd documented LISTEN_PID and LISTEN_FDS for
socket activation, they later added LISTEN_FDNAMES; now documented at:
https://www.freedesktop.org/software/systemd/man/sd_listen_fds.html
In particular, look at the implementation of sd_listen_fds_with_names():
https://github.com/systemd/systemd/blob/main/src/libsystemd/sd-daemon/sd-daemon.c
If we ever pass LISTEN_PID=xxx and LISTEN_FDS=n to a child process,
but leave LISTEN_FDNAMES=... unchanged as inherited from our parent
process, then our child process using sd_listen_fds_with_names() might
see a mismatch in the number of names (unexpected -EINVAL failure), or
even if the number of names matches the values of those names may be
unexpected (with even less predictable results).
Usually, this is not an issue - the point of LISTEN_PID is to tell
systemd socket activation to ignore all other LISTEN_* if they were
not directed to this particular pid. But if we end up consuming a
socket directed to this qemu process, and later decide to spawn a
child process that also needs systemd socket activation, we must
ensure we are not leaking any stale systemd variables through to that
child. The easiest way to do this is to wipe ALL LISTEN_* variables
at the time we consume a socket, even if we do not yet care about a
LISTEN_FDNAMES passed in from the parent process.
