027d19ee10 AT32F435: Fix RDATA pin deassert when drive is deselected. 
This was fixed for 105/415 Goteks long ago in bb7f7f0128, however
the layout of a GPIO config word is different on 435 and the O_FALSE
level specifier was at the incorrect bit offset.

2341619c0b FF.CFG: New option "rotary=v2" uses v2.x rotary encoder logic. 
This is more permissive than v3.x logic and may work better with
some cheap encoders which skip Gray-code states altogether.

e23c893f8e adf: Remember sector write order for current cylinder if it is modified. 
Although we forget as soon as the heads are stepped or disk ejected, this
is sufficient to satisfy X-Copy in verify mode when copying a source disk
with out-of-order sectors (seems rare but does happen).

b5e70de77b image: Properly implement empty/unformatted tracks beyond end of image-file track count. 
These tracks read as garbage, and ignore writes.

This fixes a bug where writing beyond an image-file limit would trash the last
cylinder's track data. This was particularly an issue for HFE image files.
