ddddce0e46e73d4ca369f2ce9696231cc579e1f9 util: Replace boost::signals2 with std::function (MarcoFalke)
Pull request description:
This removes the `#include <boost/signals2/signal.hpp>` from `util.h` (hopefully speeding up the build time and reducing the memory usage further after #13634)
The whole translation interface is replaced by a function `G_TRANSLATION_FUN` that is set to nullptr in units that don't need translation. (Thus only set in the gui)

fa5ce27385 ui: Compile boost:signals2 only once (MarcoFalke)
Pull request description:
ui is one of the modules that poison other modules with `boost/signals2` headers. This moves the include to the cpp file and uses a forward declaration in the header.
Locally this speeds up the incremental build (building everything that uses the ui module) with gcc by ~5% for me. Gcc uses ~5% less memory.
Would be nice if someone could verify the numbers roughly.
I presume the improvements will be more pronounced if the other models would stop exposing the boost header as well.

Pull request description:
Don't `assert(foo())` where `foo` has side effects.
From `assert(3)`:
> If the macro `NDEBUG` is defined at the moment `<assert.h>` was last included, the macro `assert()` generates no code, and hence does nothing at all.
Bitcoin currently cannot be compiled without assertions, but we shouldn't rely on that.

A subset of #14211 ("Use MakeUnique to construct objects owned by unique_ptrs") as suggested by @MarcoFalke in https://github.com/bitcoin/bitcoin/pull/14211#issuecomment-423324019.
Use `MakeUnique` to construct objects owned by `unique_ptr`s.
Rationale:
* `MakeUnique` ensures exception safety in complex expressions.
* `MakeUnique` gives a more concise statement of the construction.

0890339fb3 build: prefer python3.4 even if newer versions are present on the system (Sjors Provoost)
Pull request description:
Python 3.4 is this mimimum supported version according to [doc/dependencies.md](https://github.com/bitcoin/bitcoin/blob/master/doc/dependencies.md)
Systems with [PyEnv](https://github.com/pyenv/pyenv) ensure (via [.python-version](https://github.com/bitcoin/bitcoin/blob/master/.python-version)) that Python 3.4 is used
for the functional tests. However `make check` calls `bitcoin-util-test.py`
using the Python command found by `configure.ac`, which looks system wide.
On systems with multiple versions of Python this would cause `make check`
to fail, as it tries to call a version of Python that PyEnv blocks.
This is solved by preferring python3.4 in `configure.ac`.
I missed this in #14884, so ideally this should be tagged 0.18

Pull request description:
I'm hitting a corner case in my mainnet wallet where I load a restore a wallet, call `rescanblockchain` from RPC, and it's "double counting" an output I've sent to myself since currently it never marks input transactions as dirty. This is fixed by a restart of the wallet.
Note that this only happens with keys with birthdate *after* the blocks containing the spent funds which gets scanned on startup, so it's hard to test without a set seed function.

Pull request description:
This script compared paths relative to the report directory to test for exclusion,
meaning the `EXCLUDE_DIRS` directory exclusions did not work properly, as
they were relative to the project root.
Fix this by creating absolute paths through the combination of:
'git ls-files --full-name' and 'git rev-parse --show-toplevel'
Once this is done, we can stop testing for the names that would otherwise
appear when exclusion of leveldb, secp256k1, etc., did not work as intended.

93009618b6d72b6bb253cabc4a5813d7aea18a67 Fix start with the `-min` option (Hennadii Stepanov)
Pull request description:
From IRC:
> 2018-10-17T12:36:38 \<Drakon\> The option to minimize to system tray instead of the taskbar ist available, but doesn't have an effect if it is started with the -min option. If I start it via that option, I have to click on the program symbil on the taskbar and then minimize it again in order to get it minimized to system tray.
> 2018-10-17T12:37:28 \<Drakon\> That's annoying.
> 2018-10-17T13:51:19 \<wumpus\> can you open an issue for that please? https://github.com/bitcoin/bitcoin/issues/new

6dc4593db1ccfb8745b2daa42f457981ae08dba9 IsReachable is the inverse of IsLimited (DRY). Includes unit tests (marcaiaf)
Pull request description:
IsReachable is the inverse of IsLimited, but the implementation is duplicated (DRY)
- Changed the implementation accordingly.
- Added unit tests to document behavior and relationship
- My modification in net.cpp applies only to IsReachable.
- Applied clang-format-diffpy

ca126d490b0ff6960e135f3c77b2b2d4892a5744 Fix out-of-bounds write in case of failing mmap(...) in PosixLockedPageAllocator::AllocateLocked (practicalswift)
Pull request description:
`mmap(...)` returns `MAP_FAILED` (`(void *) -1`) in case of allocation failure.
`PosixLockedPageAllocator::AllocateLocked(...)` did not check for allocation failures prior to this PR.
Instead the invalid memory address `(void *) -1` (`0xffffffffffffffff`) was passed to the caller as if it was a valid address.
After some operations the address is wrapped around from `0xffffffffffffffff` to `0x00000003ffdf` (`0xffffffffffffffff + 262112 == 0x00000003ffdf`);
The resulting address `0x00000003ffdf` is then written to.
