IMFS: Add fine grained configuration

Remove miniIMFS.  Statically initialize the root IMFS.

Add configuration options to disable individual
features of the root IMFS, e.g.
  o CONFIGURE_IMFS_DISABLE_CHOWN,
  o CONFIGURE_IMFS_DISABLE_FCHMOD,
  o CONFIGURE_IMFS_DISABLE_LINK,
  o CONFIGURE_IMFS_DISABLE_MKNOD,
  o CONFIGURE_IMFS_DISABLE_MOUNT,
  o CONFIGURE_IMFS_DISABLE_READLINK,
  o CONFIGURE_IMFS_DISABLE_RENAME,
  o CONFIGURE_IMFS_DISABLE_RMNOD,
  o CONFIGURE_IMFS_DISABLE_SYMLINK,
  o CONFIGURE_IMFS_DISABLE_UNMOUNT, and
  o CONFIGURE_IMFS_DISABLE_UTIME.
