fae1374 qa: Allow for partial_match when checking init error (MarcoFalke)
5812273 [Tests] Require exact match in assert_start_raises_init_eror() (John Newbery)
0ec08a6 [Tests] Move assert_start_raises_init_error method to TestNode (John Newbery)
Pull request description:
Extracted from #12379, because the changes are important on their own.
This allows for exact testing, since the match can be specified with a strict regex. Internal details (such as exact formatting of the error message) can still be fuzzed away by regex wildcards.

a7c45bc Add native support for serializing char arrays without FLATDATA (Pieter Wuille)
Pull request description:
Support is added to serialize arrays of type `char` or `unsigned char` directly, without any wrappers. All invocations of the `FLATDATA` wrappers that are obsoleted by this are removed.
This includes a patch by @ryanofsky to make `char` casting type safe.
The serialization of `CSubNet` is changed to serialize a `bool` directly rather than though `FLATDATA`. This makes the serialization independent of the size of the bool type (and will use 1 byte everywhere).
This is a small change taken from #10785.

The tests are a little bit slow, mempool_persist.py goes from about 20 s to about 120 s in my hardware.
Perhaps there's a better way to test this.

6feb46c Add --with-sanitizers option to configure (Evan Klitzke)
Pull request description:
This adds configure options for `-fsanitize=address`, `-fsanitize=thread`, and `-fsanitize=undefined` which are all disabled by default. These flags are useful for developers who wish to do additional safety checking. Note that some of these are mutually incompatible, and these may have a large performance overhead.
There's some kind of strange logic required to properly check for the availability of these flags in a way that works on both GCC and Clang, hopefully the comments make it clear what's going on.

0bd2ec5 Improve formatting of developer notes (Evan Klitzke)
Pull request description:
The developer notes file has gotten pretty large and unwieldly. This reorganizes some content, most notably by adding a TOC to the page. Compare how the page looks in [my branch](https://github.com/eklitzke/bitcoin/blob/developer-notes/doc/developer-notes.md) vs [master](https://github.com/eklitzke/bitcoin/blob/master/doc/developer-notes.md).
I know there's long-term interest in moving a lot of this content to the bitcoin-core/docs repo on GitHub, but this makes things better now.
The TOC format here is a semi-standard extension to Markdown files that you may have seen on GitHub pages in other projects. The `<!-- markdown-toc -->` comments used by these tools to know where the TOC starts/ends. The following tools all understand this format:
* [Sphinx](http://www.sphinx-doc.org/en/master/)
* [Pandoc](https://pandoc.org/)
* [markdown-toc.el](https://github.com/ardumont/markdown-toc) (what I used)
* various plugins for [vim](https://github.com/mzlogin/vim-markdown-toc) and other editors
I used this TOC extension at a previous job, and my observation is that it's fine if people just edit the TOC manually. It's just text and it's not a huge deal if it gets a little out of sync. It can also be regenerated at any time by anyone with any of these tools.

ccedbaf Increase LevelDB max_open_files unless on 32-bit Unix. (Evan Klitzke)
Pull request description:
Currently we set `max_open_files = 64` on all architectures due to concerns about file descriptor exhaustion. This is extremely expensive due to how LevelDB is designed.
When a LevelDB file handle is opened, a bloom filter and block index are decoded, and some CRCs are checked. Bloom filters and block indexes in open table handles can be checked purely in memory. This means that when doing a key lookup, if a given table file may contain a given key, all of the lookup operations can happen completely in RAM until the block itself is fetched. In the common case fetching the block is one disk seek, because the block index stores its physical offset. This is the ideal case, and what we want to happen as often as possible.
If a table file handle is not open in the table cache, then in addition to the regular system calls to open the file, the block index and bloom filter need to be decoded before they can be checked. This is expensive and is something we want to avoid.
The current setting of 64 file handles means that on a synced node, only about 4% of key lookups can be satisifed by table file handles that are actually open and in memory.
The original concerns about file descriptor exhaustion are unwarranted on most systems because:
* On 64-bit POSIX hosts LevelDB will open up to 1000 file descriptors using `mmap()`, and it does not retain an open file descriptor for such files.
* On Windows non-socket files do not interfere with the main network `select()` loop, so the same fd exhaustion issues do not apply there.
This change keeps the default `max_open_files` value (which is 1000) on all systems except 32-bit POSIX hosts (which do not use `mmap()`). Open file handles use about 20 KB of memory (for the block index), so the extra file handles do not cause much memory overhead. At most 1000 will be open, and a fully synced node right now has about 1500 such files.

d40f06a Introduce interface for signing providers (Pieter Wuille)
Pull request description:
`CKeyStore` is a rich interface that provides many features, including knowledge of scripts and pubkeys for solving, private keys for signing, in addition to watch-only keys and scripts, and distinguishing lack of keys from them just being encrypted.
The signing logic in script/sign does not actually need most of these features. Here we introduce a simpler interface (`SigningProvider`) which *only* provides keys and scripts. This is actually sufficient for signing.
In addtion, we swap the dependency between keystore and script/sign (keystore now depends on script/script with `CKeyStore` deriving from `SigningProvider`, rather than `CKeyStore` being the interface that signing relies on).
This is a very early step towards the design in https://gist.github.com/sipa/125cfa1615946d0c3f3eec2ad7f250a2, separating the concern between deciding what outputs are ours and signing.

f38e4fd QA: Add -blocksdir test (Jonas Schnelli)
386a6b6 Allow to optional specify the directory for the blocks storage (Jonas Schnelli)
Pull request description:
Since the actual block files taking up more and more space, it may be desirable to have them stored in a different location then the data directory (use case: SSD for chainstate, etc., HD for blocks).
This PR adds a `-blocksdir` option that allows one to keep the blockfiles and the blockindex external from the data directory (instead of creating symlinks).
I fist had an option to keep the blockindex within the datadir, but seems to make no sense since accessing the index will (always) lead to access (r/w) the block files.

- Call `statusUpdateNeeded` before `tryGetTxStatus`. This allows to run
the latter only if really required i.e. if `statusUpdateNeeded` returns true.
- Reuse `cachedNumBlocks` from `WalletModel` in `TransactionTablePriv::index()` to _actually_ avoid redundant tx status updates
- Initialize `cachedNumBlocks` and `cachedChainLockHeight` with `-1` to avoid extra `pollBalanceChanged` call
bf36a3ccc212ad4d7c5cb8f26d7a22e279fe3cec gui: Fix race in WalletModel::pollBalanceChanged (Russell Yanofsky)
Pull request description:
Poll function was wrongly setting cached height to the current chain height instead of the chain height at the time of polling.
This bug could cause balances to appear out of date, and was first introduced a0704a8996 (diff-2e3836af182cfb375329c3463ffd91f8L117). Before that commit, there wasn't a problem because cs_main was held during the poll update.
Currently, the problem should be rare. But if 8937d99ce81a27ae5e1012a28323c0e26d89c50b from #17954 were merged, the problem would get worse, because the wrong cachedNumBlocks value would be set if the wallet was polled in the interval between a block being connected and it processing the BlockConnected notification.
MarcoFalke also points out that a0704a8996 could lead to GUI hangs as well, because previously the pollBalanceChanged method, which runs on the GUI thread, would only make a nonblocking TRY_LOCK(cs_main) call, but after could make blocking LOCK(cs_main) calls, potentially locking up the GUI.
Thanks to John Newbery for finding this bug this while reviewing https://github.com/bitcoin/bitcoin/pull/17954.
