isTreasuryActive

[chappjc]

Record treasury active heights for mainnet and testnet, and
correctly pass the treasuryActive bool to various functions.

txhelpers.TreasuryHeightMainnet and TreasuryHeightTestnet3.
Simnet treasury is assumed active at genesis.

Put treasury parameters on the /parameters page.

Make a Treasury transactions section on the /block page.

Also add a "Fee Rate" column to the regular transactions section,
show rates in atoms/B.

On the /tx page, label treasury inputs and outputs:

• Treasury Spend has a special input.
• Treasury Add has a special output.
• Treasurybase has special inputs and outputs.

Give timeouts for {search,send}rawtransaction RPCs

dcrpg: Also remove legacy pg db upgrades.

Next step to support a new treasury page is new PG queries or even a new treasury table to fill out a treasury page with the three types of txns:

• treasuryadd burns coins and credits the treasury account.
• treasuryspend creates coins and debits the treasury account.
• treasurybase is analogous to a coinbase in that it credits the treasury without spending/burning any coins, instead creating them out of thin air like coinbases

collect and store todo here: https://github.com/decred/dcrdata/pull/1817/files#diff-1256fb31f67b81d11af39cef8f5f93723821756f546f2b939b77d96280d5615aR3942

Also, the votes with a 4th output are used to authorize treasury spends so we should consider how to decode and track these types of votes and/or their treasury decision.
