Update to version 0.9.0

  Huge amount of changes were made since previous release.  Now
  mk-configure provides a number of mkc.*.mk scripts working on top of
  pkgsrc's mk files or Simon Gerraty's mk-files and therefore provides
  a replacement not only for GNU autoconf but for GNU automake too.
  It makes sense to reread README file.
  Lots of new information is there.

  Lots of examples (yes, hello_worlds applications :-) ) were created
  in examples/ subdirectory.

  Lots of new mkc.*.mk files were added. They work on top of bsd.*.mk
  files and provide new functions. See README.

  Regression tests were added. Thanks to them a number of bugs were
  detected and fixed.

  Fixes in configure.mk:
     - s/return/exit/ in ${.OBJDIR}/.error-check section.
       This bug is seen under Linux/bash.

     - bmake's variable SIZEOF.long_long was not set correctly
       (long-long din't work)

     - MKC_CHECK_SIZEOF+=type:header.h
       bmake's variable SIZEOF.<type>.<header_h> is set
       instead of plain SIZEOF.<type>

     - MKC_CHECK_HEADERS += dir/hdr.h
       bmake's variable: s/HAVE_HEADER.dir.hdr_h/HAVE_HEADER.dir_hdr_h/
       (`.' vs. `_')
       I hope this is a last change in configure.mk's API.

  My own mkc.intexts.mk bmake module (mk file).

  configure.mk:
    If CHECK_SIZEOF_xxx check fails, MKC_CFLAGS is not changed.  Only
    sucessful data type sizes are registered in MKC_CFLAGS and CFLAGS.

  mkc_check_decl, mkc_check_sizeof: they don't use MKC_COMMON_DEFINES
  environment enymore, everything should be passed through CFLAGS and
  CPPFLAGS.

  MKC_SHELL is currently disabled
