contrib, test: Rebase Podman patch, enable three-way merge on git am in demo

2022-08-01T10:45:05+00:00

Given that a three-way git merge was enough to cope with context
changes in man pages, it's probably a good idea to enable that for
'git am' in the demo too.

demo: Use git protocol downloads

2022-07-22T17:42:18+00:00

For some reason using https to clone from the passt git repo is very slow,
at least from network-distant places.  Use git protocol in the demo instead
to avoid a tedious wait to get the source.

tests: Use socat instead of netcat

2022-07-22T17:41:42+00:00

Commit 41c02e10 ("tests: Use nmap-ncat instead of openbsd netcat for pasta
tests") updated the pasta tests to use the nmap version of ncat instead of
the openbsd version, for greater portability.

For some upcoming changes, however, we'll be wanting to use socat.
"socat" can do everything "ncat" can and more, so let's move all the
tests using host tools (either directly on the host or via mbuto
generated images) to using socat instead.

test: Fix Podman build in Podman demo

2022-07-22T17:41:42+00:00

For some reason, I now have to update some "vendored" dependencies
on a fresh git clone, at least in my environment, before building.

test: In pasta demo, issue /sbin/dhclient instead of dhclient

2022-07-22T17:41:42+00:00

This was dependent on my own environment where I usually have /sbin
in $PATH. If that's missing, given that we're running dhclient as
user, we won't find it.

test: In demos, use pgrep instead of pstree to find namespace PID

2022-07-22T17:41:18+00:00

Parsing pstree's output is somewhat unreliable: there might be
multiple pasta instances running on the same host, and depending on
the overall output width pstree might truncate some branches.

Ask pasta to save its PID to file, and use that as parameter for
pgrep to find the PID of the interactive shell whose user and network
namespaces we want to join.

tests: Explicitly list test files in test/run, remove "onlyfor" support

2022-07-13T23:32:42+00:00

Currently test/run uses wildcards to run all of the tests in a directory.
However, that wildcard list is filtered down by the "onlyfor" directives
in the test files... usually to a single file.

Therefore, just explicitly list the files we *really* want to run for this
test mode.  This makes it easier to see at the top level what tests will
be executed, and to change that list temporarily while debugging specific
failures.

This means the "onlyfor" directive no longer has any purpose, and we can
remove it.  "onlyfor" was also the only used of the $MODE variable, so we
can remove that too.
