Generally useless information. Only updates on connect time, not after
that. Peers can easily lie and the median filter is not effective in
preventing that.
In the past it was used for progress display in the GUI but
`CheckPoints::guessVerificationProgress` provides a better way that is now used.
It was too easy to mislead it. Peers do lie about it in practice, see issue #4065.
From the RPC, `getpeerinfo` gives the peer raw values, which are more
useful.
Only messages for now, executable names and other file names
can be changed later if necessary and safe.
Do not do an all-sweeping change. Some occurences of Bitcoin-Qt need to
be kept:
- Applicationname: this is used to determine the registry entry names,
we don't want to lose settings over a silly name change.
- Where it refers to the executable name instead of the product name.
- rework window title to not include Bitcoin - in front, as no other
dialog does this
- favor a connect() call over an own function for clearing the traffic
graph
- write monospace lowercase (seems to be correct after some web search)
and add a comment that we should avoid / remove fixed font sizes
- this helps user to not think our Client is called "Bitcoin Wallet"
- change "About Bitcoin-Qt" to "About Bitcoin"
- change "Bitcoin debug window" to "Bitcoin - Debug window"
- change "Client" in debug Window to "Bitcoin Core"
* This allows copy/pasting whole or partial messages
* Handle output more consistently in console
* No more scrollbars-in-scrollbars: by setting per-pixel scrolling on the table, cells can have any height
* Decorations for "request" and "reply" are changed to the txin and txout icons instead of colored squares
