tests/docker: add NOFETCH env variable for testing
Testing non-auto built docker containers (i.e. custom built compilers)
is a bit fiddly as you couldn't continue a build with a previously
locally built container. While you can play games with REGISTRY its
simpler to allow a NOFETCH that will go through the cached build
process when you run the tests.

fixed cross-modifying code handling, but did not add a test. The
changed code was further improved recently [1], and I was not sure
whether these modifications were safe (spoiler: they were fine).
Add a test to make sure there are no regressions.

accel/tcg: add tracepoints for cpu_loop_exit_atomic
We try to avoid using cpu_loop_exit_atomic as it brings in an all-core
sync point. However on some cpu/kernel/benchmark combinations it is
starting to show up in the performance profile. To make it easier to
see whats going on add tracepoints for the slow path so we can see
what is triggering the wait.
It seems for a modern CPU it can be quite a bit, for example:

plugins: fix qemu_plugin_reset
34e5e1 refactored the plugin context initialization. After this change,
tcg_ctx->plugin_insn is not reset inconditionnally anymore, but only if
one plugin at least is active.
When uninstalling the last plugin active, we stopped reinitializing
tcg_ctx->plugin_insn, which leads to memory callbacks being emitted.
This results in an error as they don't appear in a plugin op sequence as
expected.
The correct fix is to make sure we reset plugin translation variables
after current block translation ends. This way, we can catch any
potential misuse of those after a given block, in more than fixing the
current bug.
