Introduce two new options to reach the I2P network:
* `-i2psam=<ip:port>` point to the I2P SAM proxy. If this is set then
the I2P network is considered reachable and we can make outgoing
connections to I2P peers via that proxy. We listen for and accept
incoming connections from I2P peers if the below is set in addition to
`-i2psam=<ip:port>`
* `-i2pacceptincoming` if this is set together with `-i2psam=<ip:port>`
then we accept incoming I2P connections via the I2P SAM proxy.
Implement the following commands from the I2P SAM protocol:
* HELLO: needed for all of the remaining ones
* DEST GENERATE: to generate our private key and destination
* NAMING LOOKUP: to convert .i2p addresses to destinations
* SESSION CREATE: needed for STREAM CONNECT and STREAM ACCEPT
* STREAM CONNECT: to make outgoing connections
* STREAM ACCEPT: to accept incoming connections
Introduce two high level, convenience methods in the `Sock` class:
* `SendComplete()`: keep trying to send the specified data until either
successfully sent all of it, timeout or interrupted.
* `RecvUntilTerminator()`: read until a terminator is encountered (never
after it), timeout or interrupted.
These will be convenient in the I2P SAM implementation.
`SendComplete()` can also be used in the SOCKS5 implementation instead
of calling `send()` directly.
Previously `Sock::Wait()` would not have signaled to the caller whether
a timeout or one of the requested events occurred since that was not
needed by any of the callers.
Such functionality will be needed in the I2P implementation, thus extend
the `Sock::Wait()` method.
Recognize also I2P addresses in the form `base32hashofpublickey.b32.i2p`
from `CNetAddr::SetSpecial()`.
This makes `Lookup()` support them, which in turn makes it possible to
manually connect to an I2P node by using
`-proxy=i2p_socks5_proxy:port -addnode=i2p_address.b32.i2p:port`
Co-authored-by: Lucas Ontivero <lucasontivero@gmail.com>
Our local (bind) address is already saved in `CNode::addrBind` and there
is no need to re-retrieve it again with `GetBindAddress()`.
Also, for I2P connections `CNode::addrBind` would contain our I2P
address, but `GetBindAddress()` would return something like
`127.0.0.1:RANDOM_PORT`.
Isolate the second half of `CConnman::AcceptConnection()` into a new
separate method, which could be reused if we accept incoming connections
by other means than `accept()` (first half of
`CConnman::AcceptConnection()`).
Call `GetBindAddress()` earlier in `CConnman::AcceptConnection()`. That
is specific to the TCP protocol and makes the code below it reusable for
other protocols, if the caller provides `addr_bind`, retrieved by other
means.
This check is related to an `accept()` failure. So do the check earlier,
closer to the `accept()` call.
This will allow to isolate the `accept()`-specific code at the beginning
of `CConnman::AcceptConnection()` and reuse the code that follows it.
`fclose()` is flushing any buffered data to disk, so if it fails then
that could mean that the data was not completely written to disk.
Thus, check if `fclose()` succeeds and only then claim success from
`WriteBinaryFile()`.
If an error occurs and `fread()` returns `0` (nothing was read) then the
code before this patch would have returned "success" with a partially
read contents of the file.
Extract `ReadBinaryFile()` and `WriteBinaryFile()` from `torcontrol.cpp`
to its own `readwritefile.{h,cpp}` files, so that it can be reused from
other modules.

Pull request description:
This reverts PR #211.
I disagree with this change, I use the functionality a lot, it was the primary way I used to organize and edit transactions labels and am sad to see this go.
> you can edit a sending address in the send tab Address Book
Using the address book should not be encouraged at all! A while ago it was even proposed to remove it. There's rarely need to scroll through all historical addresses used and unused. The transaction list does just fine for this.
> While all other actions apply directly to the selected transaction, the Edit Label action applies to the selected transaction's address.
**In practice** when bitcoin is used in the commonly advised way, generate a new address for each transaction, those are equivalent though.
I doubt I (and **luke-jr**) will be the only users that will stumblle on this. Further discussion here: https://github.com/bitcoin-core/gui/pull/211#issuecomment-784755998

Pull request description:
The recent requests table will allow you to copy data points even if they do not exist. This PR implements checks to disable the `copy label`, `copy message`, and `copy amount` context menu actions if the respective fields are empty. This brings the recent requests table context menu behavior closer to the behavior seen in the transaction view.
On a payment request entry which does not have a value for label, message, or amount:

`copy URI` never needs to be disabled as an entry in the recent requests table must have a URI even if it doesn't have a label, message, or amount. #213 will add a `copy address` context menu action. This also does not need a check as an entry must be associated with an address.

584fd91d2d294883e6896dbd64a2176528e94581 init: only use pipe2 if availabile, check in configure (Sebastian Falbesoner)
Pull request description:
The result of the O_CLOEXEC availability check is currently only set in the Makefile and passed to LevelDB (see `LEVELDB_CPPFLAGS_INT` in `src/Makefile.leveldb.include`), but not defined to be used in our codebase. This means that code within the preprocessor conditional `#if HAVE_O_CLOEXEC` was actually never compiled. On the master branch this is currently used for pipe creation in `src/shutdown.cpp`, PR #21007 moves this part to a new module (I found the issue while testing that PR).
The fix is similar to the one in #19803, which solved the same problem for HAVE_FDATASYNC.
In the course of working on the PR it turned out that pipe2 is not available an all platforms, hence a configure check and a corresponding define HAVE_PIPE2 is introduced and used.
The PR can be tested by anyone with a system that has pipe2 and O_CLOEXEC available by putting gibberish into the HAVE_O_CLOEXEC block: on master, everything should compile fine, on PR, the compiler should abort with an error. At least that's my naive way of testing preprocessor logic, happy to hear more sophisticated ways :-)
