Add dirstat function.

This function back-fills the missing d-type information in a
dirent on platforms that don't provide d_type in the native
dirent.

* sysif.c (DT_FIFO, DT_CHR, DT_DIR, DT_BLK, DT_REG, DT_LNK,
DT_SOCK): Define all these preprocessor symbols to their Linux
values on platforms where DT_DIR is not defined.
(DT_UNKNOWN): Make sure this symbol is #undef-d if DT_DIR
is not defined, so the corresponding dt-unknown variable does
not exist.
(dirstat): New static function.
(sysif_init): Register dirstat intrinsic. Register dt-fifo and
the rest unconditionally now. Changing their order to
increasing numeric.

* txr.1: Documented.
