958b25be50 - Introduce support for sticky bit.
- Revise VFS-FS protocol and update VFS/MFS/ISOFS accordingly.
- Clean up MFS by removing old, dead code (backwards compatibility is broken by
  the new VFS-FS protocol, anyway) and rewrite other parts. Also, make sure all
  functions have proper banners and prototypes.
- VFS should always provide a (syntactically) valid path to the FS; no need for
  the FS to do sanity checks when leaving/entering mount points.
- Fix several bugs in MFS:
  - Several path lookup bugs in MFS.
  - A link can be too big for the path buffer.
  - A mountpoint can become inaccessible when the creation of a new inode
    fails, because the inode already exists and is a mountpoint.
- Introduce support for supplemental groups.
- Add test 46 to test supplemental group functionality (and removed obsolete
  suppl. tests from test 2).
- Clean up VFS (not everything is done yet).
- ISOFS now opens device read-only. This makes the -r flag in the mount command
  unnecessary (but will still report to be mounted read-write).
- Introduce PipeFS. PipeFS is a new FS that handles all anonymous and
  named pipes. However, named pipes still reside on the (M)FS, as they are part
  of the file system on disk. To make this work VFS now has a concept of
  'mapped' inodes, which causes read, write, truncate and stat requests to be
  redirected to the mapped FS, and all other requests to the original FS.

0b8e20c89e Changes to the include files in order to make cross-compilation possible.
- The primary reason is that mkfs and installboot need to run natively during
  the cross compilation (host and target versions are compiled). There is a
  collision of include files though. E.g. a.out.h is very minix-specific.
  Therefore some files we moved and replaced by stubs that include the original
  file if compiling on or for Minix :
  
  include/a.out.h -> include/minix/a.out.h
  include/sys/dir.h -> include/minix/dir.h
  include/dirent.h -> include/minix/dirent.h
  include/sys/types.h -> include/minix/types.h

- This does not break any native compilation on Minix. Other headers that were
  including the original files are changed according to include directly the
  new, minix specific location not to pick up the host system includes while
  cross-compiling.

- role of this patch is to make rebasing of the build branch simpler until the
  new build system is merged
