The goal of the wait_for_port() function is to return when the port is
bound. This is to make sure we wait for application startup time.
This can be seen in some comments of the callers.
Commit 7e3d04fb caused this regression while reworking the logic to read
ports from /proc. I doesn't seem to cause problems in CI, properly
because the function returns before the port is bound.
I have not seen any flakes related to this but I only see the ones on
PRs where I rerun tests so it is best to wait for Ed to take a look.
Also fixes the broken ipv4_to_procfs() which only passes one argument to
__ipv4_to_procfs(), this results in the ipv4 not beeing inverted.
Therefore all bind checks against a direct ipv4 did not work.
This function accepts only an ipv4 but one caller passes localhost
which is invalid.

_test_skopeo_credential_sharing() used port_is_free() to check if a
port has no active listeners. With the new implementation, this is
not equivalent anymore: a port might be in TIME_WAIT, so it's not
free, but the listener might be long gone.
Add tcp_port_probe() to check if there's an active listener on a
given port, and use it in _test_skopeo_credential_sharing().

These tests should cover all the basic networking functionality with
pasta(1). Namely, they check:
- IPv4 and IPv6 addressing and routing settings
- TCP and UDP port forwarding over IPv4 and IPv6
- data transfers and ICMP/ICMPv6 echo requests
- the (exceedingly simple) lifecycle handling
These tests need some new helpers, to obtain IPv4 and IPv4 addresses
and routes, as well as MTU and interface names. Those use jq(1) for
parsing.
Some availability checks are implemented as well, to skip tests if
pasta(1) is not available, or if IPv4 and IPv6 are not usable.
To get consistent outcomes across distributions, and to enable
uncomplicated termination for UDP tests based on zero-sized packets,
use socat(1), which, unlike netcat, doesn't suffer from option
inconsistencies depending on flavours (traditional, BSD, NMAP) and
versions.

The main helpers.bash file is rather bloated and it's difficult to
find stuff there. Move networking functions to their own helper
file.
While at it, apply a consistent style, and rearrange logically
related functions into sections.
