Currently, it is impossible to complete jobs on standby (i.e. paused
ready jobs), but actually the only thing in mirror_complete() that does
not work quite well with a paused job is the job_enter() at the end.
If we make it conditional, this function works just fine even if the
mirror job is paused.
So technically this is a no-op, but obviously the intention is to accept
block-job-complete even for jobs on standby, which we need this patch
for first.

Prior to this patch, if a private nvme-ns device (that is, a namespace
that is not linked to a subsystem) is wired up to an nvme-subsys linked
nvme controller device, the device fails to verify that the namespace id
is unique within the subsystem. NVM Express v1.4b, Section 6.1.6 ("NSID
and Namespace Usage") states that because the device supports Namespace
Management, "NSIDs *shall* be unique within the NVM subsystem".
Additionally, prior to this patch, private namespaces are not known to
the subsystem and the namespace is considered exclusive to the
controller with which it is initially wired up to. However, this is not
the definition of a private namespace; per Section 1.6.33 ("private
namespace"), a private namespace is just a namespace that does not
support multipath I/O or namespace sharing, which means "that it is only
able to be attached to one controller at a time".
Fix this by always allocating namespaces in the subsystem (if one is
linked to the controller), regardless of the shared/private status of
the namespace. Whether or not the namespace is shareable is controlled
by a new `shared` nvme-ns parameter.
Finally, this fix allows the nvme-ns `subsys` parameter to be removed,
since the `shared` parameter now serves the purpose of attaching the
namespace to all controllers in the subsystem upon device realization.
It is invalid to have an nvme-ns namespace device with a linked
subsystem without the parent nvme controller device also being linked to
one and since the nvme-ns devices will unconditionally be "attached" (in
QEMU terms that is) to an nvme controller device through an NvmeBus, the
nvme-ns namespace device can always get a reference to the subsystem of
the controller it is explicitly (using 'bus=' parameter) or implicitly
attaching to.

Remove the unused BlockConf from the controller structure and remove the
noop constraint checking.
Device works just fine with both legacy drive parameter namespace and
nvme-ns namespace definitions.

The `nvme_nsid()` function returns '-1' (FFFFFFFFh) when the given
namespace is NULL. Since FFFFFFFFh is actually a valid namespace
identifier (the "broadcast" value), change this to be '0' since that
actually *is* the invalid value.

Added missing qemu_fflush() on buffer file holding precopy device state.
Increased initial QIOChannelBuffer allocation to 512KB to avoid reallocs.
Typical configurations often require >200KB for device state and VMDESC.

Commit 7d7dbf9dc1 introduced a new line starting with
"GIT_SUBMODULES_ACTION=" in the config-host.mak file. The grep that
tries to determine the submodules in the gitlab-ci.yml file matches
this new line, too, causing a warning message when updating the modules:
warn: ignoring non-existent submodule GIT_SUBMODULES_ACTION=update
Fix it by matching the "GIT_SUBMODULES=..." line only.

Document how multicore machines appear to GDB when debugged
via the debug stub. This is particularly non-intuitive for
the "multiple heterogenous clusters" case, but unfortunately
as far as I know there is no way with the remote protocol
for the stub to tell gdb "I have 2 inferiors, please connect
to both", so the user must set it all up manually.

Depending on the version of gdb we may not execute the first line of
SHA1Init when executing the first "next" command - instead just
stepping over the preamble. As we don't actually care about the
position of the PC after the steps and want to be sure the
context->state[] has been loaded before we inspect it do a double next
at the start.
