The getgroups test is a NetBSD tests, so just apply our larger hammer
and disable the feature entirely. The audit test can take a more
surgical approach and use __ssp_real() appropriately, since it's a local
one.

The unit tests are patterned after those for memrchr().
This catches the issue found in 293915.

After patch 9d26b82, we don't provide recursive call protection anymore.
Therefore, to pass the test, we adjust the testcase by protecting on
caller and the testcase is to make sure the dtors is properly handled.

We were saving SIGINT twice instead of SIGINT and SIGQUIT.
Also restore original order of operations (SIGINT then SIGQUIT), which
matches the order in which they're discussed in the POSIX description
of system(3).

Don't assume that SIGINT and SIGQUIT are set to SIG_DFL at the start
of the test. Instead, retrieve their current dispositions and verify
that they are restored at the end of the test.

system(3): Fix null case2026-02-25T21:12:42ZDag-Erling Smørgravdes@FreeBSD.org2026-02-25T21:12:42Zurn:sha1:8ae3f44991948cc97b09adc248a9a46db71bf9e0
Our manual page states that if given a null pointer, system() returns
non-zero if the shell is available and zero if it is not. This is
consistent with the C standard's description of system(), but it is not
what we actually do. What we actually do is always return non-zero, as
required by POSIX.
As the POSIX rationale explains, implementing the logic required by the
C standard does not violate POSIX, since a conforming system always has
a shell, therefore the logic will always return non-zero.
Since our libc is commonly used in non-conforming situations such as
chroots or thin jails, we should implement the full logic required by
the C standard.
