a7324bd Format timestamps using ISO 8601 formatting (e.g. "2018-02-28T12:34:56Z") (practicalswift)

Pull request description:

  Print timestamp strings in logs using [ISO 8601](https://en.wikipedia.org/wiki/ISO_8601) formatting (e.g. `2018-02-28T12:34:56Z`):
  * `Z` is the zone designator for the zero [UTC](https://en.wikipedia.org/wiki/Coordinated_Universal_Time) offset.
  * `T` is the delimiter used to separate date and time.

  This makes it clear for the end-user that the date/time logged is specified in UTC and not in the local time zone.

c8330d4 qa: Use node.datadir instead of tmpdir in test framework (MarcoFalke)

Pull request description:

  Commit c53c983 introduced the utility function `get_datadir_path`, however not all places in the code use this util function. Using the util function everywhere makes it easier to review pull requests related to the datadir.

  This commit replaces datadir path creation with the `datadir` member of `TestNode`, which itself uses `get_datadir_path`.

d54874d Set SCHED_BATCH priority on the loadblk thread. (Evan Klitzke)

Pull request description:

  Today I came across bitcoin#10271, and while reading the discussion dashpay#6358 was linked to. Linux systems have a `SCHED_BATCH` scheduler priority that is useful for threads like loadblk. You can find the full details at [sched(7)](http://man7.org/linux/man-pages/man7/sched.7.html), but I'll quote the relevant part of the man page below:

  > ...this policy will cause the scheduler to always assume that the thread is
  CPU-intensive. Consequently, the scheduler will apply a small scheduling penalty
  with respect to wakeup behavior, so that this thread is mildly disfavored in
  scheduling decisions.
  >
  > This policy is useful for workloads that are noninteractive, but do not want to
  lower their nice value, and for workloads that want a deterministic scheduling
  policy without interactivity causing extra preemptions (between the workload's
  tasks).

  I think this change is useful independently of bitcoin#10271 and irrespective of whether that change is merged. Under normal operation the loadblk thread will just import `mempool.dat`. However, if Bitcoin is started with `-reindex` or `-reindex-chainstate` this thread will use a great deal of CPU while it rebuilds the chainstate database (and the block database in the case of `-reindex`). By setting `SCHED_BATCH` this thread is less likely to interfere with interactive tasks (e.g. the user's web browser, text editor, etc.).

  I'm leaving the nice value unchanged (which also affects scheduling decisions) because I think that's better set by the user. Likewise I'm not using [ioprio_set(2)](http://man7.org/linux/man-pages/man2/ioprio_set.2.html) because it can cause the thread to become completely I/O starved (and knowledgeable users can use `ionice(1)` anyway).

13c3a65 Qt/Bugfix: fix handling default wallet with no name (João Barbosa)

Pull request description:

  If one loads a wallet via RPC (`loadwallet w2`), then select w2, select back to the default wallet (which is an empty string), that default wallet cannot be access through the RPC console because the current code only points to the wallet endpoint if the wallet name is not empty.

  This is a quick fix that reenables accessing the default wallet in case an additional wallet has been loaded.

  Using "" for the default wallet may not be ideal in other cases and it may make more sense to change it at a deeper level (wallet.cpp). See discussion here which where the reasons for the current behaviour in master:

3a03d2a Qt: load wallet in UI after possible init aborts (Jonas Schnelli)

Pull request description:

  Bug was introduced in bitcoin#13063 (80b4910) where bitcoin#13097 made possible to get "hit" by that bug. Reported by @ken2812221 (bitcoin#13097 (comment)).

  Dynamically loading a wallet informs the UI (and therefore makes the instance accessible) about the new wallet before all possible error cases where handled.

  Easy to reproduce by starting `bitcoin-qt --regtest --nowallet -usehd=0` then in the console enter `loadwallet wallet.dat`.

  This PR will make sure only correctly initialised (loaded) wallets will appear in the UI.
