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.
