The dtrace backend defines SDT_USE_VARIADIC as a workaround for a
conflict with a LTTng UST header file, which requires SDT_USE_VARIADIC
to be defined.
LTTng UST <lttng/tracepoint.h> breaks if included after generated dtrace
headers because SDT_USE_VARIADIC will already be defined:
#ifdef LTTNG_UST_HAVE_SDT_INTEGRATION
#define SDT_USE_VARIADIC <-- error, it's already defined
#include <sys/sdt.h>
Be more careful when defining SDT_USE_VARIADIC. This fixes the build
when both the dtrace and ust tracers are enabled at the same time.

To make deallocating partially constructed objects work, the
visit_type_STRUCT() need to succeed without doing anything when passed
a null object.
Commit cdd2b228b9 "qapi: Smooth visitor error checking in generated
code" broke that. To reproduce, run tests/test-qobject-input-visitor
with AddressSanitizer:
==4353==ERROR: LeakSanitizer: detected memory leaks
Direct leak of 16 byte(s) in 1 object(s) allocated from:
#0 0x7f192d0c5d28 in __interceptor_calloc (/usr/lib/x86_64-linux-gnu/libasan.so.4+0xded28)

SUMMARY: AddressSanitizer: 16 byte(s) leaked in 1 allocation(s).
Test case /visitor/input/fail/struct-in-list feeds a list with a bad
element to the QObject input visitor. Visiting that element duly
fails, and aborts the visit with the list only partially constructed:
the faulty object is null. Cleaning up the partially constructed list
visits that null object, fails, and aborts the visit before the list
node gets freed.
Fix the the generated visit_type_STRUCT() to succeed for null objects.

Both the dtrace and ust backends may include <sys/sdt.h> but LTTng
Userspace Tracer 2.11 and later requires SDT_USE_VARIADIC to be defined
before including the header file.
This is a classic problem with C header files included from different
parts of a program. If the same header is included twice within the same
compilation unit then the first inclusion determines the macro
environment.
Work around this by defining SDT_USE_VARIADIC in the dtrace backend too.
It doesn't hurt and fixes a missing STAP_PROBEV() compiler error when
the ust backend is enabled together with the dtrace backend.

Just build the container when run-coverity-scan is invoked with
--update-tools-only --docker. This requires moving the "docker build"
logic into the update_coverity_tools function.
The only snag is that --update-tools-only --docker requires access to
the dockerfile. For now just report an error for --src-tarball, and
"docker build" will fail if not in a source tree. Another possibility
could be to host our container images on a public registry, and use
"FROM qemu:fedora" to make the Dockerfile small enough that it can be
included directly in the run-coverity-scan script.

Our trusted docker wrapper allows run-coverity-scan to run with both

For the "run" phase this is transparent; for the "build" phase however
scripts are replaced with a bind mount (-v). This is not an issue
because the secret option is meant for secrets stored globally in the
system and bind mounts are a valid substitute for secrets that are known
