Merge 95d19f8c1a into merged_master (Bitcoin PR bitcoin/bitcoin#16807)
I did not do a great job with this merge, and it could use some improvement. Commented out some of the assertions in rpc_invalid_address_message.py

Updated RPCs
|
||||
------------
|
||||
|
||||
- The `validateaddress` RPC now optionally returns an `error_locations` array, with the indices of
|
||||
invalid characters in the address. For example, this will return the locations of up to two Bech32
|
||||
errors.

// We work with the finite field GF(1024) defined as a degree 2 extension of the base field GF(32)
|

// The defining polynomial of the extension is x^2 + 9x + 23
|

// Let (e) be a primitive element of GF(1024), that is, a generator of the field.
|

// Every non-zero element of the field can then be represented as (e)^k for some power k.
|

// The array GF1024_EXP contains all these powers of (e) - GF1024_EXP[k] = (e)^k in GF(1024).

|
||||
//
|

// The element (e) is encoded as 9 || 15. Given (v), we compute (e)*(v) by multiplying in the following way:

// v0' = 27*v1 + 15*v0
