63048ec73d [tests] Test starting bitcoind with -h and -version (John Newbery)
Pull request description:
Test that starting bitcoind/bitcoin-qt with `-h` and `-version` works as expected.
Prompted by https://github.com/bitcoin/bitcoin/pull/10762#commitcomment-28345993, which is a nullpointer dereference triggered by starting bitcoin-qt with `-h`.
On master, this test passes when run over bitcoind, but fails when running over bitcoin-qt. I used xvfb as a virtual frame buffer to test:

f7683cba7b Track negated arguments in the argument paser. (Evan Klitzke)
4f872b2450 Add additional tests for GetBoolArg() (Evan Klitzke)
Pull request description:
This change explicitly enable tracking negated options in the option parser. A negated option is one passed with a `-no` prefix. For example, `-nofoo` is the negated form of `-foo`. Negated options were originally added in the 0.6 release.
The change here allows code to explicitly distinguish between cases like `-nofoo` and `-foo=0`, which was not possible previously. The option parser does not have any changed semantics as a result of this change, and existing code will parse options just as it did before.
The motivation for this change is to provide a way to disable options that are otherwise not boolean options. For example, the `-debuglogfile` option is normally interpreted as a string, where the value is the log file name. With this change a user can pass in `-nodebuglogfile` and the code can see that it was explicitly negated, and use that to disable the log file.
This change originally split out from #12689.

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.

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.

This change significantly increases IBD performance by increasing the
amount of the UTXO index that can remain in memory. To ensure this
doesn't cause problems in the future, a static_assert on the LevelDB
version has been added, which must be updated by anyone upgrading
LevelDB.
rpc_net.py would intermittently fail on Travis, probably
due to assuming that two consecutive RPC calls were atomic.
Fix this by only testing that amounts are bounded above and
below rather than equal.
This reverts commit 7deba93bdc.
This is neither a "test" change, nor should the trusted-git-root
