As orphan state is now "network state", like in
d6ea737be1,
UnloadBlockIndex is only used during init if we end up reindexing
to clear our block state so that we can start over. However, at
that time no connections have been brought up as CConnman hasn't
been started yet, so all of the network processing state logic is
empty when its called.

Before daemonization, just probe the data directory lock and print an
early error message if possible.
After daemonization get the data directory lock again and hold on to it until exit
This creates a slight window for a race condition to happen, however this condition is harmless: it
will at most make us exit without printing a message to console.
$ src/bitcoind -testnet -daemon
Bitcoin server starting
$ src/bitcoind -testnet -daemon
Error: Cannot obtain a lock on data directory /home/orion/.bitcoin/testnet3. Bitcoin Core is probably already running.
When generating a new service key, explicitly request a RSA1024 one.
The bitcoin P2P protocol has no support for the longer hidden service names
that will come with ed25519 keys, until it does, we depend on the old
hidden service type so make this explicit.
See #9214.
c7be56d net: push only raw data into CConnman (Cory Fields)
2ec935d net: add CVectorWriter and CNetMsgMaker (Cory Fields)
b7695c2 net: No need to check individually for disconnection anymore (Cory Fields)
fedea8a net: don't send any messages before handshake or after requested disconnect (Cory Fields)
d74e352 net: Set feelers to disconnect at the end of the version message (Cory Fields)
This fixes one of the last major layer violations in the networking stack.
The network side is no longer in charge of message serialization, so it is now
decoupled from Bitcoin structures. Only the header is serialized and attached
to the payload.
CVectorWriter is useful for overwriting or appending an existing byte vector.
CNetMsgMaker is a shortcut for creating messages on-the-fly which are suitable
for pushing to CConnman.
I did a build on a windows 10 laptop and took notes, and tried
to improve the document:
- It's the Linux subsystem for Windows, not the other way around.
- Split out dependencies: general ones, 64-bit, 32-bit. Remove the
reference to `build-unix.md`, easy enough to be self-contained.
- Place 64-bit instructions first. 99% will want these.
- Installation instructions: recommend using `/` for prefix, same as we
do on gitian builds. This will allow copying the files to a usable
(from Windows) place using just `make DESTDIR=...`.
- Remove double spaces / consistent width reformatting.

47db075 qt: Plug many memory leaks (Wladimir J. van der Laan)
Also, send reject messages earlier in SendMessages(), so that disconnections are
processed earlier.
These changes combined should ensure that no message is ever sent after
fDisconnect is set.
