The custom ISC SPNEGO mechanism implementation is no longer needed on
the basis that all major Kerberos 5/GSSAPI (mit-krb5, heimdal and
Windows) implementations support SPNEGO mechanism since 2006.
This commit removes the custom ISC SPNEGO implementation, and removes
the option from both autoconf and win32 Configure script. Unknown
options are being ignored, so this doesn't require any special handling.
-fsanitize=thread hijacks dlopen() and dlclose(), therefore dlopen()
won't request -ldl to be used for linking during Autoconf test. Check
for dlsym() presence will fail and dlzexternal and dyndb system tests
won't run.

Some operating systems (e.g. Linux, FreeBSD) provide the
_Unwind_Backtrace() function in libgcc_s.so, which is automatically
linked into any binary using the functions provided by that library. On
OpenBSD, though, _Unwind_Backtrace() is provided by libc++abi.so, which
is not automatically linked into binaries produced by the stock system C
compiler.
Meanwhile, lib/isc/backtrace.c assumes that any GNU-compatible toolchain
allows _Unwind_Backtrace() to be used without any extra provisions in
the build system. This causes build failures on OpenBSD (and possibly
other systems).
Instead of making assumptions, actually check for _Unwind_Backtrace()
support in the toolchain if the backtrace() function is unavailable.

When building with "--enable-native-pkcs11 --with-openssl", OpenSSL
support is automatically disabled in favor of native PKCS#11:
checking for OpenSSL library... use of native PKCS11 instead
However, adding "--enable-openssl-hash" to the above two switches causes
the build to fail:
checking for OpenSSL library... use of native PKCS11 instead
disabled because of native PKCS11
checking for using OpenSSL for hash functions... configure: error: No OpenSSL for hash functions
In other words, "--with-openssl" and "--enable-openssl-hash" are not
behaving consistently when used together with "--enable-native-pkcs11".
Fix by automatically disabling OpenSSL hashing support when native
PKCS#11 support is enabled.
PKCS#11 support in BIND requires dlopen() support from the operating
system and thus building with "--enable-native-pkcs11 --without-dlopen"
should not be possible. Add an Autoconf check which enforces that
constraint. Adjust the pairwise testing model accordingly.
(cherry picked from commit 187dca9cf7)
Pairwise testing is a test case generation technique based on the
observation that most faults are caused by interactions of at most two
factors. For BIND, its configure options can be thought of as such
factors.
Process BIND configure options into a model that is subsequently
processed by the PICT tool in order to find an effective test vector.
That test vector is then used for configuring and building BIND using
various combinations of configure options.

The unittest.sh script tried to execute the unit tests when cmocka
development libraries was available, but kyua, the execution engine,
was not. Now, both need to be installed in the system.

The downstream distributors of BIND 9 (Debian in this case) are in
process of removing xml2-config command from the libxml2-dev package
(see Debian Bug #949056 for details). The removal of the script will
make BIND 9 to fail to build from the source when --with-libxml2=yes is
specified or not link with libxml2 when --with-libxml2=auto is specified
and then fail ABI changes (Debian Bug #949056).
When --with-libxml2=<path>, the script checks for <path>/bin/xml2-config
and uses the specified path to link with libxml2. This has been kept to
retain backwards compatibility with systems that does not ship
pkg-config.
Commit afa81ee4e4 omitted some spots in
the source tree which are still referencing the removed --with-cc-alg
"configure" option. Make sure the latter is removed completely.

`/usr/share/sgml/docbook/xsl-stylesheets` and `/usr/share/dblatex` are
places where docbook-style-xsl and, respectively, dblatex packages on
Red Hat systems put their XSL templates. Unless we hint this place it
has to be added to `./configure` manually (`--with-docbook-xsl=...`):

This commit changes the BIND cookie algorithms to match
draft-sury-toorop-dnsop-server-cookies-00. Namely, it changes the Client Cookie
algorithm to use SipHash 2-4, adds the new Server Cookie algorithm using SipHash
2-4. The change doesn't make the SipHash 2-4 to be the default algorithm, this
is up to the operator.

- "--with-geoip" is used to enable the legacy GeoIP library.
- "--with-geoip2" is used to enable the new GeoIP2 library
(libmaxminddb), and is on by default if the library is found.
- using both "--with-geoip" and "--with-geoip2" at the same time
is an error.
- an attempt is made to determine the default GeoIP2 database path at
compile time if pkg-config is able to report the module prefix. if
this fails, it will be necessary to set the path in named.conf with
geoip-directory
- Makefiles have been updated, and a stub lib/dns/geoip2.c has been
added for the eventual GeoIP2 search implementation.

Previously, only a message about missing Python was printed, which was
misleading to many users. The new message clearly states that Python
AND PLY is required and prints basic instructions how to install PLY
package.

(cherry picked from commit 8ccce7e24b)
Apply various fixes and tweaks to Python configuration logic implemented
in the "configure" script:
- Prevent PYTHON_INSTALL_DIR, which holds the value passed to the
--with-python-install-dir option, from being set to "unspec" by
default as this breaks installing Python modules when the
--with-python-install-dir option is not used.
- Make the --with-python-install-dir option also work when the Python
interpreter is specified explicitly (using --with-python=<...>).
- Improve contents and placement of error messages.
- Reduce duplication of code checking Python dependencies.
- Use Autoconf macros AS_CASE() and AS_IF() instead of plain shell
code.
- Update comments. Capitalize the word "Python" when referring to the
language itself rather than a specific executable.
