161e8d40a4 RPC: Add new getzmqnotifications method. (Daniel Kraft)
caac39b0ac Make ZMQ notification interface instance global. (Daniel Kraft)
Pull request description:
This adds a new RPC method `getzmqnotifications`, which returns information about all active ZMQ notification endpoints. This is useful for software that layers on top of bitcoind, so it can verify that ZeroMQ is enabled and also figure out where it should listen.
See #13526.

ea65182f03 [wallet] loadwallet shouldn't create new wallets. (John Newbery)
Pull request description:
A bug in the initial implementation of loadwallet meant that if the
arguement was a directory that didn't contain a wallet.dat file, a new
wallet would be created in that directory. Fix that so that if a
directory is passed in, it must contain a wallet.dat file.
Bug reported by promag (João Barbosa).

Pull request description:
`p2p_segwit.py` is a very long test, composed of multiple subtests. When it fails it's difficult to debug for a couple of reasons:
- Control flow jumps between different methods in the test class, so it's a little difficult to follow the code.
- state may be carried forward unintentionally from one subtest to the next.
Improve that by wrapping the subtests with a `@subtest` decorator which:
- logs progress
- asserts state after each subtest
As usual, I've also included a few commits which generally tidy up the test and improve style.

75848bcf40 [tests] Fix p2p_sendheaders race (John Newbery)
Pull request description:
p2p_sendheaders has a race in part 1.3.
part 1.2 sends a block to the node over the 'test_node' connection, but
doesn't wait for an inv to be received on the 'inv_node' connection. If
we get to part 1.3 before that inv has been received, then the
subsequent call to check_last_inv_announcement could fail.

927e1150bc Test: Harden lint-filenames.sh (wodry)
Pull request description:
- This fixes that only files with lower case file name suffix where found before, which contradicted the Regex to find uppercase characters in file names (including suffixes I guess).
- `--full-name` switch was added to git ls-files, to define that the found file always includes it's full path in the git project.
- since we know now that the file name includes the full path, we can harden the Regex to exclude the secp256k1 and univalue sub folders.
- use backslash line break to make code easier to read and avoid too long line.

fa1eac9cdb [qa] mininode: Expose connection state through is_connected (MarcoFalke)
Pull request description:
This gets rid of some non-type safe string comparisons and access to members that are implementation details of `class P2PConnection(asyncore.dispatcher)`. Such refactoring is required to replace the deprecated asyncore with something more sane.
Changes:
* Get rid of non-enum member `state` and replace is with bool `connected`
* Get rid of confusing argument `pushbuf` and literally just push to the buffer at the call site

3352da8da1 Add "export LC_ALL=C" to all shell scripts (practicalswift)
Pull request description:
~~Make sure `LC_ALL=C` is set when using `grep` range expressions.~~
Make sure `LC_ALL=C` is set in all shell scripts.
From the `grep(1)` documentation:
> Within a bracket expression, a range expression consists of two characters separated by a hyphen. It matches any single character that sorts between the two characters, inclusive, using the locale's collating sequence and character set. For example, in the default C locale, `[a-d]` is equivalent to `[abcd]`. Many locales sort characters in dictionary order, and in these locales `[a-d]` is typically not equivalent to `[abcd]`; it might be equivalent to `[aBbCcDd]`, for example. To obtain the traditional interpretation of bracket expressions, you can use the C locale by setting the `LC_ALL` environment variable to the value C.

86edf4a2a5 expose CBlockIndex::nTx in getblock(header) (Gregory Sanders)
Pull request description:
Recent publication of a weakness in Bitcoin's merkle tree construction demonstrates many SPV applications vulnerable to an expensive to pull off yet still plausible attack: https://bitslog.wordpress.com/2018/06/09/leaf-node-weakness-in-bitcoin-merkle-tree-design/
Including the coinbase in the txoutproof seems the most effective fix, however results in a significant efficiency downgrade. Transactors will not even know a priori what the size of their proof will be within a couple orders of magnitude, unless they use the mid-state of SHA2 as detailed in the blog post.
Some applications, like Elements blockchain platform that take SPV-style proofs have optional access to a bitcoind to verify these proofs of inclusion and check depth in the chain. Returning `CBlockIndex::nTx` would allow an extremely easy and compact way of checking the depth of the tree, with no additional overhead to the codebase, and works with pruned nodes.
`getblockheader` is arguably not the place for it, but as mentioned before, is a natural workflow for us checking depth of a block in a possibly pruned node.
We should also ensure that `verifytxoutproof` ends up validating this depth fact as well, but left this for another PR.

fa7a6cf1b3 policy: Treat segwit as always active (MarcoFalke)
Pull request description:
Now that segwit is active for a long time, there is no need to reject transactions with the reason that segwit hasn't activated.
Strictly speaking, this is a bug fix, because with the release of 0.16, we create segwit transactions in our wallet by default without checking if they are allowed by local policy.
More broadly, this simplifies the code as if "premature witness" was always set to true with the corresponding command line args.

Pull request description:
When analysing includes in the project it is often assumed that the preferred bracket include syntax (`#include <foo.h>`) mentioned in `developer-docs.md` is used consistently. @sipa:s excellent circular dependencies script [`circular-dependencies.py`](50c69b7801/contrib/devtools/circular-dependencies.py) (#13228) is an example of a script making this reasonable assumption.
This PR enables automatic Travis checking of the include syntax making sure that the bracket syntax includes (`#include <foo.h>`) is used consistently.
