Pull request description:

Note:
* I ignore several valid alternative spellings ~, but changed homogenous
to homogeneous as the latter is a more specific term according to the
Google dictionary definitions I found~
* homogenous is present in tinyformat, hence should be addressed upstream
* process' is correct only if there are plural processes

13782b8ba8 docs: add perf section to developer docs (James O'Beirne)
58180b5fd4 tests: add utility to easily profile node performance with perf (James O'Beirne)
Pull request description:
Adds a context manager to easily (and selectively) profile node performance during functional test execution using `perf`.
While writing some tests, I encountered some odd bitcoind slowness. I wrote up a utility (`TestNode.profile_with_perf`) that generates performance diagnostics for a node by running `perf` during the execution of a particular region of test code.
`perf` usage is detailed in the excellent (and sadly unmerged) https://github.com/bitcoin/bitcoin/pull/12649; all due props to @eklitzke.
### Example
```python
with node.profile_with_perf("large-msgs"):
for i in range(200):
node.p2p.send_message(some_large_msg)
node.p2p.sync_with_ping()
```
This generates a perf data file in the test node's datadir (`/tmp/testtxmpod0y/node0/node-0-TestName-large-msgs.perf.data`).
Running `perf report` generates nice output about where the node spent most of its time while running that part of the test:
```bash
$ perf report -i /tmp/testtxmpod0y/node0/node-0-TestName-large-msgs.perf.data --stdio \
| c++filt \
| less
# To display the perf.data header info, please use --header/--header-only options.

aa929abf8dc022e900755234c857541faeea8239 [docs] Update developer notes to discourage very long lines (John Newbery)
Pull request description:
Mandatory rules on line lengths are bad - there will always be cases where a longer line is more readable than the alternative.
However, very long lines for no good reason _do_ hurt readability. For example, this declaration in validation.h is 274 chars:
```c++
bool ConnectTip(BlockValidationState& state, const CChainParams& chainparams, CBlockIndex* pindexNew, const std::shared_ptr<const CBlock>& pblock, ConnectTrace& connectTrace, DisconnectedBlockTransactions& disconnectpool) EXCLUSIVE_LOCKS_REQUIRED(cs_main, m_mempool.cs);
```
That won't fit on one line without wrapping on my 27" monitor with a comfortable font size. Much easier to read is something like:
```c++
bool ConnectTip(BlockValidationState& state, const CChainParams& chainparams,
CBlockIndex* pindexNew, const std::shared_ptr<const CBlock>& pblock,
ConnectTrace& connectTrace, DisconnectedBlockTransactions& disconnectpool)
EXCLUSIVE_LOCKS_REQUIRED(cs_main, m_mempool.cs);
```
Therefore, _discourage_ (don't forbid) line lengths greater than 100 characters in our developer style guide.
100 chars is somewhat arbitrary. The old standard was 80, but that seems very limiting with modern displays.

Pull request description:
While debugging an issue I was somewhat surprised to [learn](https://github.com/bitcoin/bitcoin/pull/14164#issuecomment-419752678) that we've moved `src/univalue` from https://github.com/jgarzik/univalue to https://github.com/bitcoin-core/univalue, that these repos are both maintained and they're different.
The first mention of using the bitcoin-core repo is from late 2015 in #7157. I didn't check when the last common ancestor commit is.
I couldn't find documentation as to why (these things just happen in open source of course), but at minimum we should make this more clear.
There's also the following line in `config.ac` that I'm not sure what to do with:
```
AC_INIT([univalue], [1.0.3],

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.

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

Pull request description:
When analysing includes in the project it is often assumed that the preferred bracket include syntax (`#include <foo.h>`) mentioned in `developer-docs.md` is used consistently. @sipa:s excellent circular dependencies script [`circular-dependencies.py`](50c69b7801/contrib/devtools/circular-dependencies.py) (#13228) is an example of a script making this reasonable assumption.
This PR enables automatic Travis checking of the include syntax making sure that the bracket syntax includes (`#include <foo.h>`) is used consistently.

0a4ea2f4589961868ab4d25e0277485c31938e20 build: Add linter for checking accidental locale dependence (practicalswift)
Pull request description:
This linter will check for code accidentally introducing locale dependencies.
Unnecessary locale dependence can cause bugs that are very tricky to isolate and fix. We should avoid using locale dependent functions if possible.
Context: https://github.com/bitcoin/bitcoin/pull/12881#issuecomment-378564722
Example output:
```
$ contrib/devtools/lint-locale-dependence.sh
The locale dependent function tolower(...) appears to be used:
src/init.cpp: if (s[0] == '0' && std::tolower(s[1]) == 'x') {
Unnecessary locale dependence can cause bugs that are very
tricky to isolate and fix. Please avoid using locale dependent
functions if possible.
Advice not applicable in this specific case? Add an exception
by updating the ignore list in contrib/devtools/lint-locale-dependence.sh
```
**Note to reviewers:** What is the most appropriate `LOCALE_DEPENDENT_FUNCTIONS` function list? What should be added or removed?
