  SVN rev 211413 on 2010-08-17 09:05:39Z by kib
  
  Use the newly provided aux vectors to get pagesize and osreldate information.
  Use local version of getpagesize(), rtld_getpagesize() in private allocator.
  Override the __getosreldate() previously fetched from libc_pic.a with
  local version that uses aux value if present. Note that __getosreldate()
  is used by rtld indirectly, by mmap(2) libc wrapper.
  
  To be able to utilize aux, split digest_dynamic() for use by init_rtld()
  into two parts, where the first one does not call malloc(), and the
  second part uses it. init_rtld() is able to initialize global variables
  before digest_dynamic2() calls. In particular, pagesize and osreldate are
  set up from the aux values.
  
  Now, rtld avoids (two) sysctl calls in startup.
