    Complete rewrite the BIND 9 build system · 978c7b2e
    Ondřej Surý authored
    The rewrite of BIND 9 build system is a large work and cannot be reasonable
    split into separate merge requests.  Addition of the automake has a positive
    effect on the readability and maintainability of the build system as it is more
    declarative, it allows conditional and we are able to drop all of the custom
    make code that BIND 9 developed over the years to overcome the deficiencies of
    autoconf + custom Makefile.in files.
    
    This squashed commit contains following changes:
    
    - conversion (or rather fresh rewrite) of all Makefile.in files to Makefile.am
      by using automake
    
    - the libtool is now properly integrated with automake (the way we used it
      was rather hackish as the only official way how to use libtool is via
      automake
    
    - the dynamic module loading was rewritten from a custom patchwork to libtool's
      libltdl (which includes the patchwork to support module loading on different
      systems internally)
    
    - conversion of the unit test executor from kyua to automake parallel driver
    
    - conversion of the system test executor from custom make/shell to automake
      parallel driver
    
    - The GSSAPI has been refactored, the custom SPNEGO on the basis that
      all major KRB5/GSSAPI (mit-krb5, heimdal and Windows) implementations
      support SPNEGO mechanism.
    
    - The various defunct tests from bin/tests have been removed:
      bin/tests/optional and bin/tests/pkcs11
    
    - The text files generated from the MD files have been removed, the
      MarkDown has been designed to be readable by both humans and computers
    
    - The xsl header is now generated by a simple sed command instead of
      perl helper
    
    - The <irs/platform.h> header has been removed
    
    - cleanups of configure.ac script to make it more simpler, addition of multiple
      macros (there's still work to be done though)
    
    - the tarball can now be prepared with `make dist`
    
    - the system tests are partially able to run in oot build
    
    Here's a list of unfinished work that needs to be completed in subsequent merge
    requests:
    
    - `make distcheck` doesn't yet work (because of system tests oot run is not yet
      finished)
    
    - documentation is not yet built, there's a different merge request with docbook
      to sphinx-build rst conversion that needs to be rebased and adapted on top of
      the automake
    
    - msvc build is non functional yet and we need to decide whether we will just
      cross-compile bind9 using mingw-w64 or fix the msvc build
    
    - contributed dlz modules are not included neither in the autoconf nor automake
