Overview of differences with btcsuite codebase

[xaur]

High level overview of how dcrd/dcrwallet codebases diverged from btcd/btcwallet might be useful for new developers.

As a case in point, I've essentially rewritten txscript, secp256k1, ecdsa, schnorr, gcs, and huge swaths of blockchain just off the top of my head. Then there are others that Matheus did such as the addition of fees and basically a rewrite of bech32 to make it actually efficient.
84% new code seems very plausible.
Right, and btcd doesn't even have schnorr
Nor any of the connmgr updates like http seeding (davecgh on 2020-04-07)
