This makes chutney much more reliable, and removes the dependency
on an external DNS resolver.

This is a breaking change for those who run DNS-based queries
through chutney. To restore DNS support, use:
CHUTNEY_DNS_CONF="/etc/resolv.conf"

Closes ticket #21903, and other related tickets.

Fixes #20409, as long as chutney and tools/test-network.sh do not hang.
(Hangs shouldn't happen, if they do, it's a separate bug.)

No behaviour change

This increases integration test coverage, and improves the reliability of
any statistics being gathered on chutney networks.

Implements feature #21901.

And fix some bash-isms.
This restores support for BSDs without bash installed.

Reverts 0d57f92.
Closes 21575.

Part of tor's 21570.

Required for tor's 21570 to work.

Revision of 21571 to better suit tor's needs in 21570.

And provide a canonical path to the nodes directory in warnings.sh.

This is part of tor feature 21570.

Closes 21572.

This prepares for the tor changes in 21570.

Closes 21571.

Instead of moving the directory to a unique path at the start of the next
run, which makes it impossible to find if running several networks in
succession, like we do in 'make test-network-all'.

Closes 21567.

And handle it consistently across chutney and scripts.

Closes 21568.

Closes 21467 (finally!)

Partial fix for 20091.

Follow-up to #21371.

Closes #21563, related to tor's #21562.

If they don't, use the script path.

Finally fixes #21521, I hope!

Every call to `mkdir_p` uses mode 448 which is a sensible default. Using
this mode as the global default prevents future problems, removes
duplicate comments and simplifies existing calls.

Closes #21552.

Closes #17088.

Maybe we should fix the configs (or tor) instead?

Part of #21371.

Fixes #21548.

Add arguments to test-network.sh for warnings
Make the enviromental variables strings rather than integers

Fixes #21371.

Part of #21521.

Remaining work: make chutney python code use CHUTNEY_PATH.

Closes #21533.

Closes #21371.

Closes #21532.

uniq -c prints counts with variable spacing. We shouldn't carry that through
to the output.

Closes #21531.

Part of #21371.
