The manpages are outdated and are very rarely updated when changes
to the code happen.

Rebased-From: fae7a369cb137000897d32afab7eb13aa79ec34e fa6ce44bf98fe1dd5be779fd77b844e7016d209e
-respendnotify=<cmd> Execute command when a network tx respends wallet
tx input (%s=respend TxID, %t=wallet TxID)
Add respendsobserved array to gettransaction, listtransactions, and
listsinceblock RPCs. This omits the malleated clones that are included
in the walletconflicts array.
Add RPC help for respendsobserved and walletconflicts (help was missing
for the latter).
