- Port bios_getmem() from libi386 to {gpt,}zfsboot() and use it to

  safely allocate a heap region above 1MB.  This enables {gpt,}zfsboot()
  to allocate much larger buffers than before.
- Use a larger buffer (1MB instead of 128K) for temporary ZFS buffers.  This
  allows more reliable reading of compressed files in a raidz/raidz2 pool.
