[PATCH 0/8] t7900: untangle test dependencies

[Kristoffer Haugsbakk <code@khaugsbakk.name>]

Untangle test dependencies so that all tests only need setup tests to have
been run.

For example:

```
./t7900-maintenance.sh --run=setup,31
```

Test with:

```
#!/bin/sh
cd t
# Every test run together with `setup` should pass
for i in $(seq 1 42)
do
    ./t7900-maintenance.sh --quiet --run=setup,$i || return 1
done &&
# Whole test suite should pass
./t7900-maintenance.sh --quiet &&
# The tests that used to depend on each other should still pass
# when run together
./t7900-maintenance.sh --quiet --run=setup,30,31 &&
./t7900-maintenance.sh --quiet --run=setup,11,12 &&
./t7900-maintenance.sh --quiet --run=setup,3,19 &&
./t7900-maintenance.sh --quiet --run=setup,23,24 &&
./t7900-maintenance.sh --quiet --run=setup,33,34,35 &&
./t7900-maintenance.sh --quiet --run=setup,36,40 &&
./t7900-maintenance.sh --quiet --run=setup,36,40 &&
./t7900-maintenance.sh --quiet --run=setup,36,37 &&
./t7900-maintenance.sh --quiet --run=setup,15,23,24 &&
printf "\nAll passed\n" ||
printf '\n***Failed***\n'
```

§ CI

The CI failed but it didn't look relevant.
