feature_block.py occasionally fails on Travis. I believe this is due to
a a race condition when reconnecting to bitcoind after a subtest that
expects disconnection. If the test runs ahead and sends the INV for the
subsequent test before we've received the initial sync getheaders, then
we may end up sending two headers messages - one as a response to the
initial sync getheaders and one in response to the INV getheaders. If
both of those headers fail validation with a DoS score of 50 or higher,
then we'll unexpectedly be disconnected.
There is only one validation failure that has a DoS score bewteen 50 and
100, which is high-hash. That's why the test is failing immediately
after the "Reject a block with invalid work" subtest.
Fix is to wait for the initial getheaders from the peer before we
start populating our blockstore. That way we won't have any invalid
headers to respond to it with.

Pull request description:
As discussed at the IRC meeting back in October (https://botbot.me/freenode/bitcoin-core-dev/2017-10-12/?msg=92231929&page=2), I had looked into the feasibility of enforcing P2SH and SCRIPT_VERIFY_WITNESS back to the genesis block.
The P2SH change is pretty straightforward -- there was only one historical block on mainnet that violated the rule, so I carved out an exception to it, similar to the way we have exceptions for the BIP30 violators.
The segwit change is not entirely as clear. The code changes themselves are relatively straightforward: we can just always turn on SCRIPT_VERIFY_WITNESS whenever P2SH is active. However conceptually, this amounts to splitting up BIP141 into two parts, the part that implements new script rules, and the part that handles witness commitments in blocks.
Arguably though the script rules are really defined in BIP 143 anyway, and so this really amounts to backdating BIP 143 -- script rules for v0 segwit outputs -- back to genesis. So maybe conceptually this isn't so bad...
I don't feel strongly about this change in either direction; I started working on it because I was searching for a way to simplify the way we understand and implement the consensus rules around segwit, but I'm not yet sure whether I think this achieves anything toward that goal.

2c084a6 net: Minor accumulated cleanups (Thomas Snider)
Pull request description:
From now-derelict larger changes I had been working on, here are a series of DRY refactors/cleanups. Net loss of 35 lines of code - a small step in the good fight.
In particular I think operator!= should only ever be implemented as a negation of operator==. Lower chance for errors, and removes the possibility of divergent behavior.

Pull request description:
Not sure if these should be separate PRs.
First is removal of a platform abstraction for getting cycle counters where possible. Since the benchmarking switch to counting number of iterations over a fixed window instead of counting cycles per iteration, these are unused.
Second is removal of a few methods from the Node interface that seem vestigial from when the concepts of wallet/node were not as clearly separated.

7d8a8cc Avoid launching as admin when NSIS installer ends. (JeremyRand)
Pull request description:
The Bitcoin Core NSIS script runs with elevated privileges. Unfortunately, this means that it launches Bitcoin Core itself with elevated privileges when the user chooses to launch Bitcoin Core at the end of the installation procedure. This PR works around the issue by having `explorer.exe` launch Bitcoin Core. Seems to be a similar approach to what http://nsis.sourceforge.net/ShellExecAsUser_plug-in does, but without a plugin.
I've tested this with Sysinternals Process Explorer on Windows 10 32-bit. I wouldn't expect any differences in behavior on other Windows releases, but if anyone would like to test on other Windows releases, feel free.

2eb5036c3 macOS: Prevent Xcode 9.3 build warnings (Akio Nakamura)
Pull request description:
This PR intends to solve #12867
1. clang (Apple LLVM version 9.1.0 (clang-902.0.39.1)) warns unused argument '-pie' during compilation. This parameter should pass to the linker, so use '-Wl,-pie' style in configure.ac.
2. The other hand, when linking libbitcoinconsensus.la with passing '-Wl,-pie', ld warns that '-pie' being ignored because not link a main executable. So remove it from $libbitcoinconsensus_la_LDFLAGS in src/Makefile.am.
- In order to apply this change to Makefile, you need to run autogen.sh and ./configure.
- I think no need to add if-clause by target-os because also g++ can recognize/handle '-Wl,-pie'.
- I confirmed that the build was successful on macos10.13.4/XCode9.3 and ubuntu 17.10/g++7.2.0 and that warning was not issued.

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
