Build with `--enable-werror` under OS X.
As suggested by @TheBlueMatt in #10866. This will allow catching violations using Travis CI which does a `clang` build for OS X.

Add attribute `[[noreturn]]` (C++11) to functions that will not return.
Rationale:
* Reduce the number of false positives/false negatives from static analyzers with regards to things such as unused or unreachable code
* Potentially enable additional compiler optimizations

e666efc Get rid of redundant RPC params.size() checks (Russell Yanofsky)
Pull request description:
This is a followup to #10783.
- The first commit doesn't change behavior at all, just simplifies code.
- The second commit just changes RPC methods to treat null arguments the same as missing arguments instead of throwing type errors.
- The third commit updates developer notes after the cleanup.
- The forth commit does some additional code cleanup in `getbalance`.
Followup changes that should happen in future PRs:
- [ ] Replace uses of `.isTrue()` with calls to `.get_bool()` so numbers, objects, and strings cause type errors instead of being interpreted as false. https://github.com/bitcoin/bitcoin/pull/11050#discussion_r133850525
- [ ] Add braces around if statements. https://github.com/bitcoin/bitcoin/pull/11050#discussion_r133851133
- [ ] Maybe improve UniValue type error exceptions and eliminate RPCTypeCheck and RPCTypeCheckArgument functions. https://github.com/bitcoin/bitcoin/pull/11050#discussion_r133829303

4aa2508 Bugfix: Use testnet RequireStandard for -acceptnonstdtxn default (Luke Dashjr)
Pull request description:
Fixes a bug introduced in #8855
`-acceptnonstdtxn` is a valid option only for testnet/regtest (in Core), and the help message reflects that. Currently, however, it is buggy in two ways:
1. It uses mainnet to get the default value, which doesn't make sense since the option is never available for mainnet, and the only time the option is available, is when the default is the opposite.
2. It uses the value of "require standard" directly as the default for "accept non-standard transactions", but these concepts are opposites: a negation must be performed to transform one to the other.
Note the combination of these bugs results in the correct boolean output, but the logic to get there is completely wrong.

4452829 gitian: quick hack to fix version string in releases (Cory Fields)
Pull request description:
Credit: @luke-jr
Release version strings were broken in Gitian by #7522. This is a minimal fix suitable for 0.15.
After this, we should fix up version handling for good so that gitian packages the correct string in the release tarball, so that git is not required to get the tag name.

Instead of passing a StartShutdown reference all the way up from
txdb, give ShowProgress a "resumeable" boolean, which is used to
inform the user if the action will be resumed, but cancel is always
allowed by just calling StartShutdown().

e53615b Remove vchDefaultKey and have better first run detection (Andrew Chow)
Pull request description:
Removes vchDefaultKey which was only used for first run detection. Improves wallet first run detection by checking to see if any keys were read from the database.
This also fixes a (rather contrived) case where an encrypted non-HD wallet has corruption such that the default key is no longer valid and is loaded into a Core version that supports HD wallets. This causes a runtime exception since a new hd master key is generated as the software believes the wallet file is newly created but cannot add the generated key to the wallet since it is encrypted. I was only able to replicate this error by creating a non-hd wallet, encrypting it, then editing the wallet using `db_dump` and `db_load` before loading the wallet with hd enabled. This problem has been reported by [two](https://bitcointalk.org/index.php?topic=1993244.0) [users](https://bitcointalk.org/index.php?topic=1746976.msg17511261#msg17511261) so it is something that can happen, although that raises the question of "what corrupted the default key".
~P.S. I don't know what's up with the whitespace changes. I think my text editor is doing something stupid but I don't think those are important enough to attempt undoing them.~ Undid those

8f2f1e0 wallet: Avoid second mapWallet lookup (João Barbosa)
Pull request description:
All calls to `mapWallet.count()` have the intent to detect if a `txid` exists and most are followed by a second lookup to retrieve the `CWalletTx`.
This PR replaces all `mapWallet.count()` calls with `mapWallet.find()` to avoid the second lookup.

07685d1 Add length check for CExtKey deserialization (Jonas Schnelli)
Pull request description:
Fix a potential overwrite or uninitialised data issue.
That code part is currently unused (at least in Bitcoin Core).
We already do the same check `CExtPubKey`.

72a184a Update init.md: Fix line breaks in section 3b. (Carl Dong)
Pull request description:
Trivial commit that fixes Markdown line breaks in `docs/init.md`. Markdown line breaks take the form of two spaces, which is hard to spot when viewing raw text but visible when previewing on GitHub. Line 72-73 of `docs/init.md` did not conform to the rest the rest of the documentation, and is corrected in this PR.

Without this PR it looks like the RPC would return something like a dictionary. But it just returns the transaction in hex.

a622a1768 Fix constness of ArgsManager methods (João Barbosa)
Pull request description:
Make `cs_args` mutex mutable so that const methods can acquire it.
There's also tiny performance improvement by avoiding two map lookups when retrieving an argument value.

36d326e8b Use nullptr instead of zero (0) as the null pointer constant (practicalswift)
Pull request description:
Use `nullptr` instead of zero (0) as the null pointer constant.
The road towards `nullptr` (C++11) is split into two PRs:
* `NULL` → `nullptr` is handled in PR #10483 (scripted)
* `0` → `nullptr` is handled in PR #10645 (manual, this PR)
By using the C++11 keyword `nullptr` we are guaranteed a prvalue of type `std::nullptr_t`.
For a more thorough discussion, see "A name for the null pointer: nullptr" (Sutter &
Stroustrup), http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2007/n2431.pdf
