Add a new selftest for netconsole that tests the userdata entry limit
functionality. The test performs two key verifications:
1. Create MAX_USERDATA_ITEMS (16) userdata entries successfully
2. Confirm that attempting to create an additional userdata entry fails
The selftest script uses the netcons library and checks the behavior
by attempting to create entries beyond the maximum allowed limit.

Modify the cleanup function to remove all userdata keys created during the
test, instead of just deleting a single predefined key. This ensures a
more thorough cleanup of temporary resources.
Move the KEY_PATH variable definition inside the set_user_data function
to reduce global variables and improve encapsulation. The KEY_PATH
variable is now dynamically created when setting user data.
This change has no effect on the current test, while improving an
upcoming test that would create several userdata entries.

Split helper functions from the netconsole basic test into a separate
library file to enable reuse across different netconsole tests. This
change only moves the existing helper functions to lib/sh/lib_netcons.sh
while preserving the same test functionality.
The helpers provide common functions for:
- Setting up network namespaces and interfaces
- Managing netconsole dynamic targets
- Setting user data
- Handling test dependencies
- Cleanup operations
Do not make any change in the code, other than the mechanical
separation.

don't expose the drivers much to paths in which device stats
are read under RCU. Add tests which hammer profcs reads to

- can handle parallel reads,
- can handle device going down while reading.

The dsp_local_on selftest expects the scheduler to fail by trying to
schedule an e.g. CPU-affine task to the wrong CPU. However, this isn't
guaranteed to happen in the 1 second window that the test is running.
Besides, it's odd to have this particular exception path tested when there
are no other tests that verify that the interface is working at all - e.g.
the test would pass if dsp_local_on interface is completely broken and fails
on any attempt.
Flip the test so that it verifies that the feature works. While at it, fix a
typo in the info message.

The pattern rule `$(OUTPUT)/%: %.c` inadvertently included a circular
dependency on the global-timer target due to its inclusion in
$(TEST_GEN_PROGS_EXTENDED). This resulted in a circular dependency
warning during the build process.
To resolve this, the dependency on $(TEST_GEN_PROGS_EXTENDED) has been
replaced with an explicit dependency on $(OUTPUT)/libatest.so. This change
ensures that libatest.so is built before any other targets that require it,
without creating a circular dependency.

Fix the way tcpdump is executed by:
- Using the right variable for the namespace. Currently the use of the
empty "ns" makes the command fail.
- Waiting until it starts to capture to ensure the interesting traffic
is caught on slow systems.
- Using line-buffered output to ensure logs are available when the test
is paused with "-p". Otherwise the last chunk of data might only be
written when tcpdump is killed.

The sysctl tests for vm.memfd_noexec rely on the kernel to support PID
namespaces (i.e. the kernel is built with CONFIG_PID_NS=y). If the
kernel the test runs on does not support PID namespaces, the first sysctl
test will fail when attempting to spawn a new thread in a new PID
namespace, abort the test, preventing the remaining tests from being run.
This is not desirable, as not all kernels need PID namespaces, but can
still use the other features provided by memfd. Therefore, only run the
sysctl tests if the kernel supports PID namespaces. Otherwise, skip those
tests and emit an informative message to let the user know why the sysctl
tests are not being run.
