Subject: Library .txr files become .tl and are autoloaded.

* lisplib.c (ver_set_entries, ver_instantiate,
txr_case_set_entries, txr_case_instantiate): New
static functions.
(lisplib_init): Register new functions.

* share/txr/stdlib/txr-case.txr: Reduced to a load for the
corresponding .tl file, retained for backward compatibility.

* share/txr/stdlib/ver.txr: Likewise.

* share/txr/stdlib/txr-case.tl: New file, based on previous
contents of corresponding .txr file.

* share/txr/stdlib/ver.tl: Likewise.
