Add a BR2_PACKAGE_GNUTLS_OPENSSL option, disabled by default since it is
not used by any package that depends on gnutls.
The library is licensed under GPLv3, which can be a problem for embedded
systems due to the so-called anti-tivoization clause.

Fixes the following security issues:
* CVE-2019-3836: It was discovered in gnutls before version 3.6.7 upstream
that there is an uninitialized pointer access in gnutls versions 3.6.3 or
later which can be triggered by certain post-handshake messages
* CVE-2019-3829: A vulnerability was found in gnutls versions from 3.5.8
before 3.6.7. A memory corruption (double free) vulnerability in the
certificate verification API. Any client or server application that
verifies X.509 certificates with GnuTLS 3.5.8 or later is affected.
3.6.7.1 is identical to 3.6.7, but fixes a packaging issue in the release
tarball:

gnutls source code uses the C++11 <atomic> functionality since
7978a73346,
which internally is implemented using the __atomic_*() gcc built-ins
On certain architectures, the __atomic_*() built-ins are implemented in
the libatomic library that comes with the rest of the gcc runtime. Due
to this, code using <atomic> might need to link against libatomic,
otherwise one hits build issues such as:
../lib/.libs/libgnutls.so: undefined reference to `__atomic_fetch_sub_4'
on an architecture like SPARC.
To solve this, a configure.ac check is added to know if we need to
link against libatomic or not. The library is also added to gnutls.pc.

Gnutls is building with no default location to look for CA certs. Since
there are buildroot packages to provide these, configure it to use them
by default.
Configure gnutls to find them using the bundle file which contains all
certs, rather than looking in the cert directory. When gnutls is told
to use the directory, it loads *every* file in it. This means it loads
the bundle with all certs, then loads each cert a second time using the
individual pem files, and then loads them all the third time via the
hash symlinks to the pem files.
When p11-kit is enabled, use its trust module instead of the bundle
file. p11-kit can be configured to use the bundle (the default), but it
can do other things too, such as integrate with the "trust" command for
adding and removing trust anchors.

3.3.x kept as old-stable.
libdane now specifies LGPLv2.1+ so drop the README kludge (which is also

libunistring is a new dependency, even though gnutls ships a builtin version
we prefer to use unbundled to avoid duplication with other users and target
size growth.
