AUTOTOOLS: Add missing AC_MSG_RESULT AC_MSG_RESULT was not used everywhere after AC_MSG_CHECKING. Therefore two lines from configure output was mixed in some cases.

AUTOTOOLS: Add -LLIBDIR to PYTHON_LIBS Detect directory with python libraries and add this directory to the list of directories to be searched for linker.

Fix python HBAC bindings for python <= 2.4 Several parts of the HBAC python bindings did not work with old Python versions, such as the one shipped in RHEL5. The changes include: * a compatibility wrapper around python set object * PyModule_AddIntMacro compat macro * Py_ssize_t compat definition * Do not use PyUnicode_FromFormat * several function prototypes and structures used to have "char arguments where they have "const char *" in recent versions. This caused compilation warnings this patch mitigates by using the discard_const hack on python 2.4
