These changes are extracted from #15112 as suggested by @MarcoFalke to ease review. This is in service of enabling `-Wzero-as-null-pointer-constant`, which should eliminate this as a concern going forward. Note there are 2 non-Qt changes: `src/test/allocator_tests.cpp` and `src/wallet/db.cpp`.

Mostly, I layed out the concept to open the PR for refinement and getting feedback if the approach is okay. Changes are expected. Two points: - The values for both new consts `TESTNET_BLOCK_CHAIN_SIZE` and `TESTNET_CHAIN_STATE_SIZE` is certainly not optimal; I just checked the size of my testnet3 related dirs and set them to little bit higher values. Which values should be used? - Should we do something like this to regtest? Or these "niceties" do not matter when on regtest? Thanks!

This is fine, as long as our node is connected to other nodes. However, when we fall back and get stuck at a particular height (e.g. taking the wallet offline), the same (potentially unique) locktime is used for all transactions. This makes it easier for passive observers to cluster transactions by wallet.

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 Created new pull request to avoid the mess with: https://github.com/bitcoin/bitcoin/pull/15044 Checked with supposedly conflicting PRs mentioned in the old PR. No conflicts with the specific changes in this PR. Tree-SHA512: b132dec6cc2c788ebe4f63f228d78f441614e156743b17adebc990de0180a5872874d2724c86eeaa470b4521918bd137b0e33ebcaae77c5efc1f0d56104f6c87

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.
