`/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=...`):
https://src.fedoraproject.org/rpms/bind/blob/master/f/bind.spec#_691.

Weak symbols are handled differently by different dynamic linkers. With
glibc, lib/dns/tests/tkey_test works as expected no matter whether
--with-libtool is used or not: __attribute__((weak)) prevents a static
build from failing and it just so happens that the desired symbols are
picked at runtime for dynamic builds. However, with BSD libc, the
libdns functions called from lib/dns/tests/tkey_test.c use the "real"
memory allocation functions from libisc, thus breaking that unit test.
(Note: similar behavior can be reproduced with glibc by setting the
LD_DYNAMIC_WEAK environment variable.)
The simplest way to make lib/dns/tests/tkey_test work reliably is to
drop all uses of __attribute__((weak)) in it - this way, the memory
functions inside lib/dns/tests/tkey_test.c will always be used instead
of the "real" libisc ones for dynamic builds. However, this would not
work with static builds as it would result in multiple strong symbols
with the same name being present in a single binary.
Work around the problem by only compiling in the overriding definitions
of memory functions when building using --with-libtool. For static
builds, keep relying on the --wrap linker option for replacing calls to
the functions we are interested in.
Add check for creating new EVP_PKEY with EVP_PKEY_SIPHASH, but disable SipHash
on OpenSSL 1.1.1 as the hash length initialization is broken before OpenSSL
1.1.1a release.
The change fixes the following build failure on sparc T3 and older CPUs:
```
sparc-unknown-linux-gnu-gcc ... -O2 -mcpu=niagara2 ... -c rwlock.c
{standard input}: Assembler messages:
{standard input}:398: Error: Architecture mismatch on "pause ".
{standard input}:398: (Requires v9e|v9v|v9m|m8; requested architecture is v9b.)
make[1]: *** [Makefile:280: rwlock.o] Error 1
```
`pause` insutruction exists only on `-mcpu=niagara4` (`T4`) and upper.
The change adds `pause` configure-time autodetection and uses it if available.
config.h.in got new `HAVE_SPARC_PAUSE` knob. Fallback is a fall-through no-op.
Build-tested on:
- sparc-unknown-linux-gnu-gcc (no `pause`, build succeeds)
- sparc-unknown-linux-gnu-gcc -mcpu=niagara4 (`pause`, build succeeds)

There's no strong reason to keep `make tags` in our build system. The previous
functionality of `make tags` could be simply retained by aliasing variant of:
etags $(git ls-files '*.c' '*.h')
which would be universal for all C-code projects.
The isc-config.sh script was introduced before pkg-config as is a purely
historical thing. There are two reason for removal of isc-config.sh scripts:
a) The BIND 9 libraries are now meant to be used only from BIND 9, so there's no
reason to provide convenience script to link with the libraries.
b) Even if that was not the case, we should and would replace the isc-config.sh
with respective pkg-config (.pc) file for every library.
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, and changes the default for the Server Cookie algorithm to be siphash24.
Add siphash24 cookie algorithm, and make it keep legacy aes as
- "--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.
When GNU C Compiler is used on Solaris (11), the Thread Local Storage
is completely broken. The behaviour doesn't manifest when GNU ld is
used. Thus, we need to enforce usage of GNU ld when GNU C Compiler is
the compiler of choice.

The ax_check_openssl m4 macro used OPENSSL_INCLUDES. Rename the
subst variable to OPENSSL_CFLAGS and wrap AX_CHECK_OPENSSL() in
action-if-not-found part of PKG_CHECK_MODULE check for libcrypto.
The libxml2 have previously leaked into the global namespace leading
to forced -I<include_path> for every compilation unit using isc/xml.h
header. This MR fixes the usage making the caller object opaque.
Previously the autoconf script set sysconfdir to /etc and localstatedir to /var
if they were not explicitly set in the ./configure invocation. This MR reverts
the override and make it more in line with default and generally expected
autoconf behavior.
AM_MAINTAINER_MODE macro adds ability to disable rebuilding build file
(Makefile.in, configure, ...) when the source file changes. This is
important in the CI where the timestamps could get skewed and that
triggers the rebuild on every ./configure run.
Pull and use several autoconf archive convenience macros to simplify
configure.ac.
* AX_CHECK_COMPILE_FLAG(FLAG, ...) - check whether given CFLAG works
* AX_CHECK_LINK_FLAG(FLAG, ...) - check whether given LDFLAG works
* AX_CHECK_PREPROC_FLAG(FLAG, ...) - check whether give CPPFLAG works
* AX_SAVE_FLAGS/AX_RESTORE_FLAGS - save and restore *FLAGS
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.
