* Custom M4 macro are replaced with those to be used in the new ICON building
  system.
* Removed cfortran.h: the mangling scheme for Fortran symbols is detected at
  the configure-time.
* The precious variables for setting flags resuired to enable external
  packages (e.g. MTIME_C_INCLUDE, MTIME_C_LIB, etc.) are renamed to *_CFLAGS
  and *_CLIBS to better reflect their purpose. If those variables are set as
  command-line arguments of the configure script, the script checks only the
  given values literally, i.e. the script does not try to append and check any
  additional linking or compilation flags.
* The definition of functions declared in yac_lapack_interface.h is moved
  to a separate file yac_lapack_interface.c. And the choice of the interface
  is made with a single preprocessor macro YAC_LAPACK_INTERFACE_ID.
* The default suffix for include files for libxml2 is
  <XML2_ROOT>/include/libxml2 instead of <XML2_ROOT>/include.
* The configure script argument '--without-mpi-pack-external' is renamed to
  '--disable-mpi-pack-external' to reflect that it belongs to the section
  'Optional Features' and not to 'Optional Packages'. If the usage of
  MPI_Pack_external is disabled, the corresponding configure-time tests are
  skipped.
* The configure script argument '--without-regard-for-quality' is renamed to
  '--enable-mpi-checks' (defaults to 'yes'). Previously, the argument allowed
  for ignoring the failures of the configure-time tests of MPI_Pack_external.
  Now the argument allows for skipping the tests at all when specifying a
  valid interactive MPI_LAUNCH command is not possible.
* MPI_LAUNCH does not have to be a full path to an MPI launcher executable
  anymore: the value of the variable is interpreted as a command.
* AR, ARFLAGS, and RANLIB are precious variable now and appear in the help
  message of the configure script.
* The configure script does not try to detect MPI libraries, it only checks
  whether they are available (see comments in configure.ac).

Refactoring for lapack interface detection, added a bundled version of LAPACK (based on Netlib clapack).

The main idea of the refactoring of the tests is that
test programs do not skip themselves (do not exit with 77).
If a test needs to be skipped, it is done by the wrapper
shell script. If a test program is supposed to be skipped,
it doesn't get built at all.

* This way error output from MPI tests goes to config.log instead of
  console.

* Otherwise ifort without -fltconsistency fails the test.

* Also supports Fortran dependency tracking with Cray compiler.
