Log Message:
libmaa was updated to version 1.4.0
  License has been changed from LGPL to MIT, permitted by Rik Faith,
  original author of this library.

  Build system changed from autoshit to mk-configure.

  Library version/soname was bumped from 3 to 4. I cannot
  guarantee that mk-configure and libtool build shared library the
  same way.

  Tests were added for stk_*, mem_* and prm_* functions.

  stk_isempty function was added.

  stk_* and other was reimplemented without obstack functions (glibc
  extension).
