On Ubuntu 24.04, llvm-symbolizer-18, which is used to resolve symbols
in backtraces, links libcurl.so.4 for some reason. And that in turn
requires SRP. If our custom build doesn't provide it, we get stuff
like this
/usr/bin/llvm-symbolizer-18: symbol lookup error: /lib/x86_64-linux-gnu/libcurl.so.4: undefined symbol: SSL_CTX_set_srp_password, version OPENSSL_3.0.0
and the symbols are not resolved and can't be whitelisted.
This also makes sure ASan is actually disabled if our own leak-detective
is used.
Self-signed trust anchors are not part of the certificate path validation
according to RFC 8280, section 6.1:
When the trust anchor is provided in the form of a self-signed
certificate, this self-signed certificate is not included as part of
the prospective certification path.
But policies in them could still be used, as stated in section 6.2:
Where a CA distributes self-signed certificates to specify trust
anchor information, certificate extensions can be used to specify
recommended inputs to path validation. For example, a policy
constraints extension could be included in the self-signed
certificate to indicate that paths beginning with this trust anchor
should be trusted only for the specified policies. [...]
Implementations that use self-signed certificates to specify trust
anchor information are free to process or ignore such information.
So unconditionally enforcing that self-signed root certificates contain
the policies is probably too strict. Often they won't contain the
extension at all. With this change, we allow that but still enforce the
policies in case such a certificate contains them. The other
policy-related constraints are also enforced still should they be
contained.

Some scenarios disable route installation and if they are executed before
any scenarios that don't, there won't be a rule for table 220 and we get
"FIB table does not exist" errors.
Directly calling setup.py is deprecated (apparently has been for a while,
but now we get large warnings). Direct installation is also discouraged.
So this removes that option. The built wheel (the old egg format is not
used/built anymore) can be installed manually in a venv or the like.
The previous approach had two drawbacks:
First, it caused duplicate public keys because when the `certificate_t`
object was created and added to the credential set it had no subject
assigned yet. So it defaulted to the key ID. However, all previously
loaded keys had their subject already changed to an identity, so there
never was a match and new objects were always added whenever a config
with raw public keys was loaded.
Second, the subject was replaced in a way that's not thread-safe on an
object that's already shared in the public credential set. So other
threads could potentially access the `identification_t` object that's
destroyed during that process.

If a migrate of a child-create occurs then labels_i and labels_r are
freed, but the pointers are left set. If the task is subsequently
destroyed without being reused, then both of these will be double
freed.
Fix this by setting labels_i and labels_r to NULL in the migrate
method after freeing, similar to other fields that are freed.

There are a lot of files without patterns and running them all through
sed is quite slow. Using grep first makes this quicker (about 0.5s per
test). Ignoring PEM files is also helpful.
In particular the swanctl calls all take a while and this allows doing
them in parallel if multiple hosts are involved. This reduces the runtime
of each test by 1-3 seconds.
Both variables `inbound_installed` and `outbound_state` are used in
`child_sa_t::destroy()` to determine whether inbound and outbound state
have to be deleted. They are assigned prior to the call to
`kernel_interface_t::add_sa()`. As this call may fail, the destructor may
try to delete a state which it has not been added.
By making the assignment of these variables dependent on the success of
the state addition, we can make sure, a `child_sa_t::destroy()` only
deletes states it has added.
Also removed the redundant checks for `my_spi` and `other_spi` being set
along with the check for the above flags. It seems that when the flags
are set, the SPIs *must* be set.

If the lifetime of an issuing or sub CA is twice the lifetime of
the end entity certificates issued by it and the renewal cycle of
the issuing CAs is a little shorter than the validity of the end
entity certificates then three generations of CA certificates have
to be handled by the cert-enroll scripts.
These have been discouraged for a long time and there are now more and
more crypto libraries that have them disabled by default. However, for
some we only can detect this at runtime, in particular in FIPS mode, so
tests would fail as the plugins would still announce them. So instead
we just remove the schemes from these tests for now (at least for RSA,
removing signatures with SHA-1 completely isn't an option yet as that's
still the default with some clients).

In particular for the first one randomization could trigger an additional
rekeying, which let the "Adding ESA ..." check fail. But even without
randomization (could be seen in the second scenario that already uses
`rand_time=0`) 4 seconds can apparently be too low some time.
When compiling with -O3 with GCC 14, we get the following warning/error:
/usr/include/x86_64-linux-gnu/bits/string_fortified.h:29:10: error: '__builtin_memcpy' offset [0, 3] is out of the bounds [0, 0] [-Werror=array-bounds=]
29 | return __builtin___memcpy_chk (__dest, __src, __len,
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
30 | __glibc_objsize0 (__dest));
| ~~~~~~~~~~~~~~~~~~~~~~~~~~
Which seems completely bogus as that array has a fixed size of 16 and
some weird workarounds remove the warning (e.g. adding an assignment
to `subset->netbits` before the `memcpy()`). This is also the only
place GCC complains about and we use `memcpy()` all over the place
in this file to set those addresses.
