Replace strange $TEST_FUNCTIONS variable/expansion thing with
something more like what we use in nbdkit, a simple tests/functions.sh
script that gets sourced into each test script.
Update the common submodule to get:

mlcustomize, mltools: Replace $TEST_FUNCTIONS
TEST_FUNCTIONS is being removed from libguestfs and guestfs-tools (it
was removed from virt-v2v a while back). Make the same adjustment in
the common submodule.
(and some other commits which are not relevant to libguestfs)
Run this command across the source:
perl -pi.bak -e 's/(20[012][0-9])-20[12][012]/$1-2023/g' `git ls-files`
and remove changes to po{,-docs}/*.po{,t} (these will be regenerated
later when we run 'make dist').
Before this change the tests ran in about 12m34 and afterwards in
about 6m20, although the real change is more dramatic if you only run
tests from the tests/ subdirectory (as language tests still run serially).
This breaks valgrinding for now, which I intend to fix properly later.
Replace the monolithic 'test-max-disks.pl' script with a test program
written in C. The program is completely equivalent to the old script,
except for the enhancement that it is able to detect if disks are
added to the appliance in the wrong order.
The tests themselves are split out into some shell scripts:
- test-27-disks: Fully tests 27 disks.
This is the minimum supported configuration for all backends.
- test-255-disks: Fully tests 255 disks.
This is the most disks that libguestfs up to 1.36 supported.
- test-add-lots-of-disks: Add ‘a lot’ of disks and exit (without
any further testing). This is meant to try to exercise > 255
disk case but without being as slow as a test of the max number
of disks (which takes ages, even for as few as 4000 disks).
- test-max-disks: Test the maximum possible number of disks.
The maximum depends on several factors, notably which backend
is in use, and the limit on the number of open files.
‘test-max-disks’ is a slow test.
