Update to libmaa-1.4.5
  * err_* functions:
      Fix segfault caused by "ap" is used twice.  Solution is to va_copy
          it and use copied "ap" for printing to stderr.
    Improve formatting (no empty lines in log files)
  * err_set_program_name: handle correctly NULL argument
  * log_mkpath function: avoid use of alloca(3)
  * hsh_pointer_compare function now follows -1/0/1 logic
  * Add more tests for log_*, err_*, hsh_* and set_* function
