kichikuou b9f4c7c03a Compatibility fix for Bx commands 
These commands accept 0-127 as valid window numbers, which were 1-128
before this change.

To maintain savedata compatibility, window positions are saved in the
order 1,...,127,0.

kichikuou 2d2c6aa373 Remove strvar_len 
The length limit of string variables was removed a long time ago, but it
was recorded in save files.

Now the first argument of MZ0 is completely ignored (as in System3.9).
The maxlen field in the save file is set to a constant so that older
versions of xsystem35 can load it.

kichikuou 47e7f5542e Remove sl_retFar2 
In System39.exe `%0` drops stack frames for label calls (Rance4 v2
relies on this behavior), so it's the same as `UD 1`.

* Add support for UC3 command

kichikuou 99632397da Enable the hack in Rance4v2 recompiled with System3.9 
The System3.9 compiler compiles `MT` command to `0x2F28`, so the hack

kichikuou 50d7d7ee33 Fix handling of multi-volume ALD with inconsistent indexes 
When contents of the index table differ between ALD files, System3.x
uses information from the file containing the entry.

For example, if link_table[k] in SA.ALD is { file_nr = 2, ptr_no = 10 }
and link_table[k] in SB.ALD is { file_nr = 2, ptr_no = 11 }, the entry
body is in SB.ALD, so ptr_no = 11 should be used.

CA_G*.ALD of Child Assassin has this issue.
