A fairly random collection of fixes in this tree. I've still got a
report of openbsd rebuilding which is confusing me but I didn't want
to hold up getting eyes on real fixes.
The plugins register support may get added to the PR if it gets any
review.
The following need review:

New subject: [PATCH 1/5] tests/docker: Add sqlite3 module to openSUSE Leap container
From: Fabiano Rosas <farosas(a)suse.de>
Avocado needs sqlite3:
Failed to load plugin from module "avocado.plugins.journal":
ImportError("Module 'sqlite3' is not installed.
Use: sudo zypper install python311 to install it")
From 'zypper info python311':
"This package
supplies rich command line features provided by
readline, and sqlite3 support for the interpreter core, thus forming
a so called "extended" runtime."
Include the appropriate package in the lcitool mappings which will
guarantee the dockerfile gets properly updated when lcitool is
run. Also include the updated dockerfile.

New subject: [PATCH 2/5] docs: mark CRIS support as deprecated
This might be premature but while streamling the avocado tests I
realised the only tests we have are "check-tcg" ones. The aging
fedora-criss-cross image works well enough for developers but can't be
used in CI as we need supported build platforms to build QEMU.
Does this mean the writing is on the wall for this architecture?

New subject: [PATCH 3/5] configure: run plugin TCG tests again
From: Paolo Bonzini <pbonzini(a)redhat.com>
Commit 39fb3cfc28b ("configure: clean up plugin option handling", 2023-10-18)
dropped the CONFIG_PLUGIN line from tests/tcg/config-host.mak, due to confusion
caused by the shadowing of $config_host_mak. However, TCG tests were still
expecting it. Oops.
Put it back, in the meanwhile the shadowing is gone so it's clear that it goes
in the tests/tcg configuration.

This regressed qemu-system-xtensa:
TEST test_load_store on xtensa
qemu-system-xtensa: Some ROM regions are overlapping
These ROM regions might have been loaded by direct user request or by default.
They could be BIOS/firmware images, a guest kernel, initrd or some other file loaded
into guest memory.
Check whether you intended to load all this guest code, and whether it has been built to
load to the correct addresses.
The following two regions overlap (in the memory address space):
test_load_store ELF program header segment 1 (addresses 0x0000000000001000 -
0x0000000000001f26)
test_load_store ELF program header segment 2 (addresses 0x0000000000001ab8 -

0x0000000000001ab8)
Hmm -- this second segment is zero length, so why did we create
a ROM blob for it? The commit being reverted here looks like it
ought to be expanding the set of things for which we say
"zero size, ignore entirely"...
Anyway, revert given we have a regression is the first thing
to do if there's not an immediately obvious fix.
