23333b7ed243071c9b4e4f04c727556d8065acbb net: Allow DNS lookups on nodes with IPV6 lo only (Max Edwards)
Pull request description:
This is similar to (but does not fix) https://github.com/bitcoin/bitcoin/issues/13155 which I believe is the same issue but in libevent.
The issue is on a host that has IPV6 enabled but only a loopback IP address `-proxy=[::1]` will fail as `[::1]` is not considered valid by `getaddrinfo` with `AI_ADDRCONFIG` flag. I think the loopback interface should be considered valid and we have a functional test that will try to test this: `feature_proxy.py`.
To replicate the issue, run `feature_proxy.py` inside a docker container that has IPV6 loopback ::1 address without specifically giving that container an external IPV6 address. This should be the default with recent versions of docker. IPV6 on loopback interface was enabled in docker engine 26 and later ([https://docs.docker.com/engine/release-notes/26.0/#bug-fixes-and-enhancements-2](https://docs.docker.com/engine/release-notes/26.0/#bug-fixes-and-enhancements-2)).
`AI_ADDRCONFIG` was introduced to prevent slow DNS lookups on systems that were IPV4 only.
References:
Man section on `AI_ADDRCONFIG`:
```
If hints.ai_flags includes the AI_ADDRCONFIG flag, then IPv4 addresses are returned in the list pointed to by res only if the local system has at least one IPv4 address configured, and IPv6 addresses
are returned only if the local system has at least one IPv6 address configured. The loopback address is not considered for this case as valid as a configured address. This flag is useful on, for ex‐
ample, IPv4-only systems, to ensure that getaddrinfo() does not return IPv6 socket addresses that would always fail in connect(2) or bind(2).
```

Pull request description:
This pull originally resolved a code `TO-DO`, as well as fixing different param names between the function declaration and definition, updating the function to current style standards, clearer variable naming, and improving the Doxygen documentation.
Following the merge of #17160, it now does the non-`TODO` changes and also now drops an unused param to simplify the function.

Pull request description:
The functions that could lock this mutex, i.e., `{S,G}etProxy()`, `{S,G}etNameProxy()`, `HaveNameProxy()`, `IsProxy()`, do not call itself recursively, and do not call each other either directly or indirectly. Therefore, the `g_proxyinfo_mutex` could be a non-recursive mutex.

Make reasoning about dependencies easier by not including unused dependencies.
Please note that the removed headers are _not_ "transitively included" by other still included headers. Thus the removals are real.
As an added bonus this change means less work for the preprocessor/compiler. At least 51 393 lines of code no longer needs to be processed:
```
$ git diff -u HEAD~1 | grep -E '^\-#include ' | cut -f2 -d"<" | cut -f1 -d">" | \
sed 's%^%src/%g' | xargs cat | wc -l
51393
```
Note that 51 393 is the lower bound: the real number is likely much higher when taking into account transitively included headers :-)

Pull request description:
poll should block until there is data to be read or the timeout expires.
Filtering for the POLLOUT event causes poll to return immediately which leads to high CPU usage when trying to connect to non-responding peers through tor.
When USE_POLL is not defined select is used with the writefds parameter set to nullptr.
Removing POLLOUT causes the behavior of poll to match that of select.
Fixes: #16004.

e3245f2e7b Removes Boost predicate.hpp dependency (251)
Pull request description:
This pull request removes the `boost/algorithm/string/predicate.hpp` dependency from the project.
To replace the the `predicate.hpp` dependency from the project the function calls to `boost::algorithm::starts_with` and `boost::algorithm::ends_with` have been replaced with respectively C++11's `std::basic_string::front` and `std::basic_string::back` function calls.
Refactors that were not required, but have been done anyways:
- The Boost function `all` was implicitly made available via the `predicate.hpp` header. Instead of including the appropriate header, function calls to `all` have been replaced with function calls to `std::all_of`.
- The `boost::algorithm::is_digit` predicate has been replaced with a custom `IsDigit` function that is locale independent and ASCII deterministic.

9ad6746ccd Use static_cast instead of C-style casts for non-fundamental types (practicalswift)
Pull request description:
A C-style cast is equivalent to try casting in the following order:
1. `const_cast(...)`
2. `static_cast(...)`
3. `const_cast(static_cast(...))`
4. `reinterpret_cast(...)`
5. `const_cast(reinterpret_cast(...))`
By using `static_cast<T>(...)` explicitly we avoid the possibility of an unintentional and dangerous `reinterpret_cast`. Furthermore `static_cast<T>(...)` allows for easier grepping of casts.
For a more thorough discussion, see ["ES.49: If you must use a cast, use a named cast"](https://isocpp.github.io/CppCoreGuidelines/CppCoreGuidelines#es49-if-you-must-use-a-cast-use-a-named-cast) in the C++ Core Guidelines (Stroustrup & Sutter).

Pull request description:
As @laanwj mentioned [here](https://github.com/bitcoin/bitcoin/pull/13418#discussion_r197645385), using option `onlynet=tor` is deprecated.
I think it would be good to give the user a depcreaction warning feedback, so users can switch to `onlynet=onion` so there is a perspective for removing the deprecated `tor` in the future to decrease confusion.
Currently, users maybe just wonder that they can use a undocumented option, or they are not aware that they use a deprecated option.
Alternatively for the log warning message, I think at least this deprecetaion should be documented in the source code in a comment for readers of the source code.

2c084a6 net: Minor accumulated cleanups (Thomas Snider)
Pull request description:
From now-derelict larger changes I had been working on, here are a series of DRY refactors/cleanups. Net loss of 35 lines of code - a small step in the good fight.
In particular I think operator!= should only ever be implemented as a negation of operator==. Lower chance for errors, and removes the possibility of divergent behavior.
