[UM-2]

* Re-greening of gitlab-ci.

- There are continuing issues with cross-i386-tci. Occasionally I see *really* long test times:

with qtest-aarch64/qom-test taking 1738s, or 28 of the 60 minute budget.

More often it's merely slow:

with qtest-aarch64/qom-test taking 538s. Note that locally this test runs in about 100s, and I have been unable to determine why it runs so much slower on gitlab.

- Worked on a ppc64-softmmu slowdown leading to timeouts. - Fixes for meson regressions affecting testing.

* Refresh tcg unaligned user patch sets.
