libstand - Fix excessive memory use by hammer2 module

* Don't try to dynamically allocate 64KB for each open file.  Just use
  the same static media buffer that normal operations use.

  This fixes some severe heap fragmentation and out-of-memory issues
  when a lot (20+) modules are specified in /boot/loader.conf that
  can cause the boot loader to fail.

* Add getheap() to retrieve heap stats.
