This commit removes BIP70 support. Since this was the only thing our
payment sernver supported (we had previously dropped support for
bitcoin: urls) I also dropped all the paymentrequest logic.
96cb597325 gui: Avoid redundant tx status updates (Russell Yanofsky)
Pull request description:
This PR is part of the [process separation project](https://github.com/bitcoin/bitcoin/projects/10).
In `TransactionTablePriv::index`, avoid calling `interfaces::Wallet::tryGetTxStatus` if the status is up to date as of the most recent `NotifyBlockTip` notification. Store height from the most recent notification in a new `ClientModel::cachedNumBlocks` variable in order to check this.
This avoids floods of IPC traffic from `tryGetTxStatus` with #10102 when there are a lot of transactions. It might also make the GUI a little more efficient even when there is no IPC.

Pull request description:
This adds a checkbox to the intro screen to enable pruning from the get go.
If the user has plenty of space, it's unchecked by default:
<img width="671" alt="big" src="https://user-images.githubusercontent.com/10217/63641289-10339000-c6ac-11e9-98d7-caf64dff0da6.png">
If the user has insufficient space it's checked by default:
<img width="897" alt="low" src="https://user-images.githubusercontent.com/10217/63641276-d4002f80-c6ab-11e9-9f5b-a53472f814ff.png">
When the user has barely enough space and is likely to need pruning in the near future, this is shown in yellow and we also check the prune box:
<img width="662" alt="medium" src="https://user-images.githubusercontent.com/10217/63641294-1c1f5200-c6ac-11e9-8ecb-6b69e42b1ece.png">
The cut-off for this 10 GB above `m_assumed_blockchain_size` (`=240` in `chainparams.cpp`).
If the user launches the first time with `-prune=...` then we disable the check box and display the correct size (rounded to GB):
<img width="658" alt="Schermafbeelding 2019-08-24 om 20 23 14" src="https://user-images.githubusercontent.com/10217/63641351-09594d00-c6ad-11e9-94fe-fe5ed562e109.png">
The 2 GB default matches the settings default. The user can't change it in the intro screen, but can change it later. I'm tempted to increase that default to 10 GB, and then have the intro screen reduce it if space is really tight.
Tips for testing:
* move your existing data dir elsewhere
* wipe data dir at every restart (behavior is different if it exists)
* launch with `bitcoin-qt -resetguisettings -lang=en` (there's some space issues in different languages)
* fake your free space by changing `intro.cpp` line 90: `freeBytesAvailable = 5000000000; // 5 GB`
* try both testnet and mainnet, because settings are seperate. In particular note how step 7 in `GuiMain` switches where `QTSettings settings` points to; this had me thoroughly confused on testnet, because I was setting them too early.

utACK 9924bce317. The changes are very logical, and implement the feature in a clean that way that doesn't add a lot of complication and shouldn't interfere with future improvements. I looked at Luke's branch too, and I think there's also a lot of great stuff there that seems fully compatible with this change.
