Jack Grigg 026977744c ZIP 316: Fix bug in transparent constraint on diversifier index 
The largest valid integer for any BIP 32 path element with a defined
hardening state (in this case, non-hardened) is 2^32 - 1 (being the
31-bit integer with all bits set to 1). The range of valid diversifier
indices for transparent-including UAs is defined as end-inclusive in
the ZIP, but used the end-exclusive bound 2^32.

Jack Grigg 78b7d8489f ZIP 32: Revert all refinements 
The hardened change path approach is being dropped. ZIP 316 will include
separate amendments (to be made later) that derive change addresses
within each protocol's key tree, instead of at the spend authorization
level.
