Pull request description:
Since 2016, with [macOS 10.12 Sierra](https://en.wikipedia.org/wiki/MacOS_Sierra), Mac OS X has been renamed in macOS. It would be a nice if Bitcoin's macOS build instructions follow this naming convention to avoid misunderstandings.

ee5e896 Organise Linux build instructions to be categorised by distro (Alex Vear)
4c85517 Add NetBSD build instruction links (Alex Vear)
Pull request description:
* Added references to the newly created [`doc/build-netbsd.md`] (#12294) instructions in the [`doc/README.md`] and the [`doc/build-unix.md`] files.
* Organise [`doc/build-unix.md`] dependency build instructions by Linux distribution. This will help discoverability of dependency build instructions for specific distros. Future instructions will also be able to be added easier.
I am not quite sure about the FreeBSD instructions being in the [`doc/build-unix.md`], while both the OpenBSD and NetBSD instructions are contained within separate files ([`doc/build-openbsd.md`] and [`doc/build-netbsd.md`] respectively).
Feedback is greatly appreciated. 😄

Pull request description:
I'm re-opening #11857 as a new pull request because the last one stopped loading for people
-------------------------------
This refactors the tx index code to be in it's own class and get built concurrently with validation code. The main benefit is decoupling and moving the txindex into a separate DB. The primary motivation is to lay the groundwork for other indexers that might be desired (such as the [compact filters](https://github.com/bitcoin/bips/pull/636)). The basic idea is that the TxIndex spins up its own thread, which first syncs the txindex to the current block index, then once in sync the BlockConnected ValidationInterface hook writes new blocks.
### DB changes
At the suggestion of some other developers, the txindex has been split out into a separate database. A data migration runs at startup on any nodes with a legacy txindex. Currently the migration blocks node initialization until complete.
### Open questions
- Should the migration of txindex data from the old DB to the new DB block in init or should it happen in a background thread? The downside to backgrounding it is that `getrawtransaction` would return an error message saying the txindex is syncing while the migration is running.
### Impact
In a sample size n=1 test where I synced nodes from scratch, the average time [Index writing](https://github.com/bitcoin/bitcoin/blob/master/src/validation.cpp#L1903) was 3.36ms in master and 1.72ms in this branch. The average time between `UpdateTip` log lines for sequential blocks between 400,000 and IBD end on mainnet was 0.297204s in master and 0.286134s in this branch. Most likely this is just variance in IBD times, but I can try with some more trials if people want.

Seems like older versions of macOS pretend to support c++17 std libs but do not have/have issues with uncaught_exceptions. "Catch", the testing framework used in the bls lib wants those by default but setting `DCATCH_CONFIG_NO_CPP17_UNCAUGHT_EXCEPTIONS` disables them which should be just fine to do in all cases here.

The bugreport linked with this code is for an unrelated? issue, however from what I can tell the correct QTBUG is this one https://bugreports.qt.io/browse/QTBUG-20880. Reading though the discussion there, it seems that the way progress bars are animated changed in macOS 10.10.
Qt was patched [here (5.5+)](https://codereview.qt-project.org/#/c/112379/):
> Disable progress bar animations on 10.10 Yosemite and higher - the native style does not animate them any more. Keep the indeterminate progress bar animation.
Given all of that, I don't think this is worth keeping around, as it would seem to only be useful in the case that a macOS user is compiling with a Qt < 5.5. That should be pretty unlikely, as we don't support downloaded Qt binaries, and brew currently provides [5.11.1](571b46213c/Formula/qt.rb).

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.

fa3c910bfeab00703c947c5200a64c21225b50ef test: Move linters to test/lint, add readme (MarcoFalke)
Pull request description:
This moves the checks and linters from `devtools` to a subfolder in `test`. (Motivated by my opinion that the dev tools are mostly for generating code and updating the repo whereas the linters are read-only checks.)
Also, adds a readme to clarify that checks and linters are only meant to prevent bugs and user facing issues, not merely stylistic preference or inconsistencies. (This is motivated by the diversity in developers and work flows as well as existing code styles. It would be too disruptive to change all existing code to a single style or too burdensome to force all developers to adhere to a single style. Also note that our style guide is changing, so locking in at the wrong style "too early" would only waste resources.)

fad0fc3c9a Refine travis check for duplicate includes (MarcoFalke)
Pull request description:
Since there is no harm in having "duplicate" includes and it makes it obvious what are the dependencies of each file, without having to do static analysis or jumping between files, I'd suggest to revert the travis check for duplicate includes.
Generally, I think that enforcing minor style preferences should not be done via travis. The cost of maintaining and the burden on other developers is too high. C.f discussion in https://github.com/bitcoin/bitcoin/pull/10973#discussion_r180142594
