These seem to indicate the major and minor version of the protocol, like
e.g. for the DPD vendor ID. Some implementations seem to send versions
other than 1.0 so we just ignore these for now when checking for known
vendor IDs.
Fixes#2088.
By aborting the active task we don't have to wait for potential
retransmits if the other peer does not respond to the current task.
Since IKEv1 has no sequential message IDs and INFORMATIONALs are no real
exchanges this should not be a problem.
Fixes#1537

This change allows selectively modifying the default plugin list by setting
the `load` setting of individual plugins (e.g. to disable them or to change
their priority) without enabling charon.load_modular and having to configure
a section and a load statement for every plugin.
If a function we whitelist allocates memory while leak detective is enabled
but only frees it after LD has already been disabled, free() will get called
with invalid pointers (not pointing to the actually allocated memory by LD),
which will cause checks in the C library to fail and the program to crash.
This tries to detect such cases and calling free with the correct pointer.
Lots of static data is allocated in this function, which isn't freed until
the library is unloaded (we can't call OPENSSL_cleanup() as initialization
would fail when calling it again later). When enabling the leak
detective the test runner eventually crashes as all the data allocated during
initialization has an invalid size when freed after leak detective has been
unloaded.
There is currently no way to compare the outer and inner algorithms
encoded in a parsed CRL. X509_CRL_verify() does not seem to check that
either, though (unlike X509_verify()).
We can't call OPENSSL_cleanup() as that would prevent us from
re-initializing the library again (which we use in the Android app, that
loads/unloads plugins).
