Pull request description:
Currently our wallet code will treat bare multisig outputs (meaning scriptPubKeys with multiple public keys + `OP_CHECKMULTISIG` operator in it) as ours without the user asking for it, as long as all private keys in it are in our wallet.
This is a pointless feature. As it only works when all private keys are in one place, it's useless compared to single key outputs (P2PK, P2PKH, P2WPKH, P2SH-P2WPKH), and worse in terms of space, cost, UTXO size, and ability to test (due to lack of address format for them).
Furthermore, they are problematic in that producing a list of all `scriptPubKeys` we accept is not tractable (it involves all combinations of all public keys that are ours). In further wallet changes I'd like to move to a model where all scriptPubKeys that are treated as ours are explicit, rather than defined by whatever keys we have. The current behavior of the wallet is very hard to model in such a design, so I'd like to get rid of it.
I think there are two options:
* Remove it entirely (do not ever accept bare multisig outputs as ours, unless watched)
* Only accept bare multisig outputs in situations where the P2SH version of that output would also be acceptable
This PR implements the first option. The second option was explored in #12874.

Pull request description:
Deprecate all accounts functionality and make it only accessible by using `-deprecatedrpc=accounts`.
Accounts specific RPCs, account arguments, and account related results all require the `-deprecatedrpc=accunts` startup option now in order to see account things.
Several wallet functional tests use the accounts system. Those tests are unchanged, except to start the nodes with `-deprecatedrpc=accounts`. We can slowly migrate those tests to use the 'label' API instead of the 'account' API before accounts are fully removed.

The weekly meeting on [2017-12-07](http://www.erisian.com.au/meetbot/bitcoin-core-dev/2017/bitcoin-core-dev.2017-12-07-19.00.log.html) discussed allowing options to bitcoin to have some sensitivity to what network is in use. @theuni suggested having sections in the config file:
<cfields> an alternative to that would be sections in a config file. and on the
cmdline they'd look like namespaces. so, [testnet] port=5. or -testnet::port=5.
This approach is (more or less) supported by `boost::program_options::detail::config_file_iterator` -- when it sees a `[testnet]` section with `port=5`, it will treat that the same as "testnet.port=5". So `[testnet] port=5` (or `testnet.port=5` without the section header) in bitcoin.conf and `-testnet.port=5` on the command line.
The other aspect to this question is possibly limiting some options so that there is no possibility of accidental cross-contamination across networks. For example, if you're using a particular wallet.dat on mainnet, you may not want to accidentally use the same wallet on testnet and risk reusing keys.
I've set this up so that the `-addnode` and `-wallet` options are `NETWORK_ONLY`, so that if you have a bitcoin.conf:
wallet=/secret/wallet.dat
upnp=1
and you run `bitcoind -testnet` or `bitcoind -regtest`, then the `wallet=` setting will be ignored, and should behave as if your bitcoin.conf had specified:
upnp=1
[main]
wallet=/secret/wallet.dat
For any `NETWORK_ONLY` options, if you're using `-testnet` or `-regtest`, you'll have to add the prefix to any command line options. This was necessary for `multiwallet.py` for instance.
I've left the "default" options as taking precedence over network specific ones, which might be backwards. So if you have:
maxmempool=200
[regtest]
maxmempool=100
your maxmempool will still be 200 on regtest. The advantage of doing it this way is that if you have `[regtest] maxmempool=100` in bitcoin.conf, and then say `bitcoind -regtest -maxmempool=200`, the same result is probably in line with what you expect...
The other thing to note is that I'm using the chain names from `chainparamsbase.cpp` / `ChainNameFromCommandLine`, so the sections are `[main]`, `[test]` and `[regtest]`; not `[mainnet]` or `[testnet]` as might be expected.

Suggested formatting for namespaces in the developer guide is currently
inconsistent. This commit updates the developer guide and clang-format
configuration to consistently put "namespace" and opening/closing braces
on the same line. Example:
```c++
namespace boost {
namespace signals2 {
class connection;
} // namespace signals2
} // namespace boost
```
Currently the "Source code organization" section has an example like the one
above, but the "Coding style" section example and description put a newline
between the opening "namespace foo" and brace (but oddly no newline between
closing namespace and brace).
Avoiding newlines before namespace opening braces makes nested declarations
less verbose and also avoids asymmetry with closing braces. It's also a
common style used in other codebases:
* https://google.github.io/styleguide/cppguide.html#Namespaces
* https://developer.mozilla.org/en-US/docs/Mozilla/Developer_guide/Coding_Style#Classes
* https://llvm.org/docs/CodingStandards.html#namespace-indentation
fad0fc3c9a Refine travis check for duplicate includes (MarcoFalke)
Pull request description:
Since there is no harm in having "duplicate" includes and it makes it obvious what are the dependencies of each file, without having to do static analysis or jumping between files, I'd suggest to revert the travis check for duplicate includes.
Generally, I think that enforcing minor style preferences should not be done via travis. The cost of maintaining and the burden on other developers is too high. C.f discussion in https://github.com/bitcoin/bitcoin/pull/10973#discussion_r180142594

Pull request description:
This is a refactoring PR that does not change behavior in any way. This change:
1. Creates abstract [`Node`](https://github.com/ryanofsky/bitcoin/blob/pr/ipc-local/src/interface/node.h) and [`Wallet`](https://github.com/ryanofsky/bitcoin/blob/pr/ipc-local/src/interface/wallet.h) interfaces in [`src/interface/`](https://github.com/ryanofsky/bitcoin/tree/pr/ipc-local/src/interface)
1. Updates Qt code to call the new interfaces. This largely consists of diffs of the form:
```diff
- InitLogging();
- InitParameterInteraction();
+ node.initLogging();
+ node.initParameterInteraction();
```
This change allows followup PR #10102 (makes `bitcoin-qt` control `bitcoind` over an IPC socket) to work without any significant updates to Qt code. Additionally:
* It provides a single place to describe the interface between GUI and daemon code.
* It can make better GUI testing possible, because Node and Wallet objects have virtual methods that can be overloaded for mocking.
* It can be used to help make the GUI more responsive (see https://github.com/bitcoin/bitcoin/issues/10504)
Other notes:
* I used python scripts [hide-globals.py](https://github.com/ryanofsky/home/blob/master/src/2017/hide-globals/hide-globals.py) and [replace-syms.py](https://github.com/ryanofsky/home/blob/master/src/2017/hide-globals/replace-syms.py) to identify all the places where Qt code was accessing libbitcoin global variables and calling functions accessing those global variables.
* These changes were originally part of #10102. Thanks to @JeremyRubin for the suggestion of splitting them out.

These flags are useful for developers who wish to do additional safety checking. Note that some of these are mutually incompatible, and these may have a large performance overhead.
There's some kind of strange logic required to properly check for the availability of these flags in a way that works on both GCC and Clang, hopefully the comments make it clear what's going on.

0bd2ec5 Improve formatting of developer notes (Evan Klitzke)
Pull request description:
The developer notes file has gotten pretty large and unwieldly. This reorganizes some content, most notably by adding a TOC to the page. Compare how the page looks in [my branch](https://github.com/eklitzke/bitcoin/blob/developer-notes/doc/developer-notes.md) vs [master](https://github.com/eklitzke/bitcoin/blob/master/doc/developer-notes.md).
I know there's long-term interest in moving a lot of this content to the bitcoin-core/docs repo on GitHub, but this makes things better now.
The TOC format here is a semi-standard extension to Markdown files that you may have seen on GitHub pages in other projects. The `<!-- markdown-toc -->` comments used by these tools to know where the TOC starts/ends. The following tools all understand this format:
* [Sphinx](http://www.sphinx-doc.org/en/master/)
* [Pandoc](https://pandoc.org/)
* [markdown-toc.el](https://github.com/ardumont/markdown-toc) (what I used)
* various plugins for [vim](https://github.com/mzlogin/vim-markdown-toc) and other editors
I used this TOC extension at a previous job, and my observation is that it's fine if people just edit the TOC manually. It's just text and it's not a huge deal if it gets a little out of sync. It can also be regenerated at any time by anyone with any of these tools.

This change significantly increases IBD performance by increasing the
amount of the UTXO index that can remain in memory. To ensure this
doesn't cause problems in the future, a static_assert on the LevelDB
version has been added, which must be updated by anyone upgrading
LevelDB.

Pull request description:
Rename account to label where appropriate
This change only updates strings and adds RPC aliases, but should simplify the implementation of address labels in https://github.com/bitcoin/bitcoin/pull/7729, by getting renaming out of the way and letting that change focus on semantics.
The difference between accounts and labels is that labels apply only to addresses, while accounts apply to both addresses and transactions (transactions have "from" and "to" accounts). The code associating accounts with transactions is clumsy and unreliable so we would like get rid of it.

Tree-SHA512: b3f934e612922d6290f50137f8ba71ddfaea4485713c7d97e89400a8b73b09b254f9186dffa462c77f5847721f5af9852b5572ade5443d8ee95dd150b3edb7ff
The blockmaxsize option was marked as deprecated in V0.15.1, and code
was added to convert provided blockmaxsize into blockmaxweight. However,
this code was incorrectly implemented, and blockmaxsize was silently
ignored.
No users have complained about blockmaxsize being ignored, so just
remove it in V0.17.
This change only updates strings and adds RPC aliases, but should simplify the
implementation of address labels in
https://github.com/bitcoin/bitcoin/pull/7729, by getting renaming out of the
way and letting it focus on semantics.
The difference between accounts and labels is that labels apply only to
addresses, while accounts apply to both addresses and transactions
(transactions have "from" and "to" accounts). The code associating accounts
with transactions is clumsy and unreliable so we would like get rid of it.
