Bring in the ext2fs work done by Aditya Sarawgi during and after Google Summer

of Code 2009:

- BSDL block and inode allocation policies for ext2fs. This involves the use
  FFS1 style block and inode allocation for ext2fs. Preallocation was removed
  since it was GPL'd.
- Make ext2fs MPSAFE by introducing locks to per-mount datastructures.
- Fixes for kern/122047 PR.
- Various small bugfixes.
- Move out of gnu/ directory.
