Set a delay of three seconds at the beginning of the test. Otherwise,
the node will send a neighbour solicitation with a blank link local
address, it won't receive a reply, and the test will fail.
This patch is a reduced version of an earlier one, with the bare minimum
required to be able to run the test and get the release going.
Original description:
atoi() cannot detect errors. Many implementation return zero on error
and that is what was being checked here, making the "udp send" command
unable to parse integer values of zero. On top of this, the behavior on
errors does not seem to be specified in the standard (so it is not even
correct to check for zero even when zero is not an accepted value, like
for a port number).
The result of all this is that sending UDP packets of zero length (as
required by the Release Specs) was not possible.
This patch replaces atoi by strlen, which allows for robust error detection.
Sending zero length packets is possible.
Also remove binding of the DNS server to 2001:db8::1. It causes
`dnsmasq` to send router advertisements from that address, which is
not a [valid source for RAs][RFC 4861], so a default route is never
configured on the RIOT to reach the DNS server.

This allows querying the build system if there are test available.
Before, one should rely on 'info-debug-variable-TESTS' to print the list
of test files. But was not reliable as sometime the build system printed
messages anyway.
BOARD=esp32-wroom-32 make --silent --no-print-directory \
-C examples/hello-world/ info-debug-variable-TESTS
ESP32_SDK_DIR should be defined as /path/to/esp-idf directory
ESP32_SDK_DIR is set by default to /opt/esp/esp-idf

Now the return code can be trusted.
This commit adds a README.md to the testing folder.
It explains the basic about how to run a test with testrunner.
It adds a reference so it will be displayed on the doxygen docs.
There currently is not obvious documentation for running tests.
If the memory is exhausted during the allocation of the new `head` structure, subsequent accesses to `head` will result in dereferencing of a NULL pointer.
Update the test as sem_timedwait is not supposed to return before the
given abstime.
Source: http://pubs.opengroup.org/onlinepubs/9699919799.2016edition/functions/sem_timedwait.html
The timeout shall expire when the absolute time specified by abstime
passes, as measured by the clock on which timeouts are based (that is,
when the value of that clock equals or exceeds abstime), or if the
absolute time specified by abstime has already been passed at the time
of the call.
