The first command creates a regular expression for matching all bitcoin-config.h symbols in the following form: ^(?!//).*(AC_APPLE_UNIVERSAL_BUILD|BOOST_PROCESS_USE_STD_FS|...|_LARGE_FILES). It was generated with:
./autogen.sh && printf '^(?!//).*(%s)' $(awk '/^#undef/ {print $2}' src/config/bitcoin-config.h.in | paste -sd "|" -)

The second command holds a list of files and directories that should not be processed. These include subtree directories as well as some crypto files that already get their symbols through the makefile.

The third command checks for missing bitcoin-config headers in .cpp files and adds the header if it is missing.

The fourth command checks for missing bitcoin-config headers in .h files and adds the header if it is missing.

The fifth command checks for unneeded bitcoin-config headers in sources files and removes the header if it is unneeded.

Merge bitcoin/bitcoin#28649: Do the SOCKS5 handshake reliably
af0fca530e netbase: use reliable send() during SOCKS5 handshake (Vasil Dimov)
1b19d1117c sock: change Sock::SendComplete() to take Span (Vasil Dimov)

Pull request description:

  The `Socks5()` function which does the SOCKS5 handshake with the SOCKS5 proxy sends bytes to the socket without retrying partial writes.

  `send(2)` may write only part of the provided data and return. In this case the caller is responsible for retrying the operation with the remaining data. Change `Socks5()` to do that. There is already a method `Sock::SendComplete()` which does exactly that, so use it in `Socks5()`.

  A minor complication for this PR is that `Sock::SendComplete()` takes `std::string` argument whereas `Socks5()` has `std::vector<uint8_t>`. Thus the necessity for the first commit. It is possible to do also in other ways - convert the data in `Socks5()` to `std::string` or have just one `Sock::SendComplete()` that takes `void*` and change the callers to pass `str.data(), str.size()` or `vec.data(), vec.size()`.

  This came up while testing https://github.com/bitcoin/bitcoin/pull/27375.

netbase: use reliable send() during SOCKS5 handshake
`send(2)` can be interrupted or for another reason it may not fully
complete sending all the bytes. We should be ready to retry the send
with the remaining bytes. This is what `Sock::SendComplete()` does,
thus use it in `Socks5()`.

Since `Sock::SendComplete()` takes a `CThreadInterrupt` argument,
change also the recv part of `Socks5()` to use `CThreadInterrupt`
instead of a boolean.

Easier reviewed with `git show -b` (ignore white-space changes).

Merge bitcoin/bitcoin#26078: p2p: return CSubNet in LookupSubNet
fb3e812277 p2p: return `CSubNet` in `LookupSubNet` (brunoerg)

Pull request description:

  Analyzing the usage of `LookupSubNet`, noticed that most cases uses check if the subnet is valid by calling `subnet.IsValid()`, and the boolean returned by `LookupSubNet` hasn't been used so much, see:
  29d540b7ad/src/httpserver.cpp (L172-L174)
  29d540b7ad/src/net_permissions.cpp (L114-L116)

  It makes sense to return `CSubNet` instead of `bool`.

net: move MaybeFlipIPv6toCJDNS() from net to netbase
It need not be in the `net` module and we need to call it from
`LookupSubNet()`, thus move it to `netbase`.

net: move IsReachable() code to netbase and encapsulate it
`vfLimited`, `IsReachable()`, `SetReachable()` need not be in the `net`
module. Move them to `netbase` because they will be needed in
`LookupSubNet()` to possibly flip the result to CJDNS (if that network
is reachable).

In the process, encapsulate them in a class.

`NET_UNROUTABLE` and `NET_INTERNAL` are no longer ignored when adding
or removing reachable networks. This was unnecessary.

style: rename hSocket to sock
In the arguments of `InterruptibleRecv()`, `Socks5()` and
`ConnectThroughProxy()` the variable `hSocket` was previously of type
`SOCKET`, but has been changed to `Sock`. Thus rename it to `sock` to
imply its type, to distinguish from other `SOCKET` variables and to
abide to the coding style wrt variables' names.

net: use Sock in InterruptibleRecv() and Socks5()
Use the `Sock` class instead of `SOCKET` for `InterruptibleRecv()` and
`Socks5()`.

This way the `Socks5()` function can be tested by giving it a mocked
instance of a socket.

net: add RAII socket and use it instead of bare SOCKET
Introduce a class to manage the lifetime of a socket - when the object
that contains the socket goes out of scope, the underlying socket will
be closed.

In addition, the new `Sock` class has a `Send()`, `Recv()` and `Wait()`
methods that can be overridden by unit tests to mock the socket
operations.

The `Wait()` method also hides the
`#ifdef USE_POLL poll() #else select() #endif` technique from higher
level code.

net: move CloseSocket() from netbase to util/sock
Move `CloseSocket()` (and `NetworkErrorString()` which it uses) from
`netbase.{h,cpp}` to newly added `src/util/sock.{h,cpp}`.

This is necessary in order to use `CloseSocket()` from a newly
introduced Sock class (which will live in `src/util/sock.{h,cpp}`).
`sock.{h,cpp}` cannot depend on netbase because netbase will depend
on it.

net: move MillisToTimeval() from netbase to util/time
Move `MillisToTimeval()` from `netbase.{h,cpp}` to
`src/util/system.{h,cpp}`.

This is necessary in order to use `MillisToTimeval()` from a newly
introduced `src/util/sock.{h,cpp}` which cannot depend on netbase
because netbase will depend on it.

util: refactor upper/lowercase functions
This includes renaming Downcase() to ToLower() and make it return a string rather than modify referenced arg.
Also adds ToUpper() string version.
