cd9c6994c2 Implement named devnets (#1791)
* Initial devnet

* Move genesis block adding into its own method

* Introduce -allowprivatenet to lift limitation on RFC1918 addresses

Normally, RFC1918 (192.168.x.x/10.x.x.x/...) addresses are not allowed
to be relayed. Also, masternodes won't start when the address is considered
invalid.

This is needed to test local devnet or regtest based networks.

* Lift the requirement of minimum MN age for regtest/devnet

* Implement named devnets

This allows the creation of multiple independent devnets. Each one is
identified by a name which is hardened into a "devnet genesis" block,
which is automatically positioned at height 1. Validation rules will
ensure that a node from devnet=test1 never be able to accept blocks
from devnet=test2. This is done by checking the expected devnet genesis
block.

The genesis block of the devnet is the same as the one from regtest. This
starts the devnet with a very low difficulty, allowing us to fill up
needed balances for masternodes very fast.

Also, the devnet name is put into the sub-version of the VERSION message.
If a node connects to the wrong network, it will immediately be disconnected.

* Allow to select multiple addresses from the same group in devnet/regtest

The selection code normally only allows to select addresses from the same
group (e.g. 192.168.x.x) once. This results in connecting to only a single
node in devnet/regtest.

* Show the devnet name in the title bar and on the loading screen

* Add AllowMultipleAddressesFromGroup to chainparams and use it in net.cpp

* Remove unused/unneeded scripts from devnet geneses creation

1. OP_RETURN not needed in input script of devnet genesis
2. genesisOutputScript was unused

* Fix copy/paste error in -allowprivatenet description

* Improve -devnet parameter error handling

- Only allow one of -devnet, -regtest or -testnet
- Only allow -devnet=name to be specified once

* Use different datadir for each devnet

* Fix `devnet-devnet` issue

* Fix devnet splashscreen (should use testnet img)

* Avoid passing devNetName around (most of the time)

* Remove nMaxTipAge from CDevNetParams

b82b9787d2 Backport Bitcoin PR#8128: Net: Turn net structures into dumb storage classes (#1604)
* net: Split resolving out of CNetAddr

* net: Split resolving out of CService

* net: Split resolving out of CSubNet

* net: move CNetAddr/CService/CSubNet out of netbase

* net: narrow include scope after moving to netaddress

Net functionality is no longer needed for CAddress/CAddrman/etc. now that
CNetAddr/CService/CSubNet are dumb storage classes.

* net: Add direct tests for new CSubNet constructors

* net: Have LookupNumeric return a CService directly

Also fix up a few small issues:
- Lookup with "badip:port" now sets the port to 0
- Don't allow assert to have side-effects

* net: fixup nits

b41d9eac22 Backport Bitcoin PR#7868: net: Split DNS resolving functionality out of net structures (#1601)
* net: require lookup functions to specify all arguments

To make it clear where DNS resolves are happening

* net: manually resolve dns seed sources

Note: Some seeds aren't actually returning an IP for their name entries, so
they're being added to addrman with a source of [::].

This commit shouldn't change that behavior, for better or worse.

* net: resolve outside of storage structures

Rather than allowing CNetAddr/CService/CSubNet to launch DNS queries, require
that addresses are already resolved.

This greatly simplifies async resolve logic, and makes it harder to
accidentally leak DNS queries.

* net: disable resolving from storage structures

CNetAddr/CService/CSubnet can no longer resolve DNS.

42c784dc7a Backport Bitcoin PR#9289: net: drop boost::thread_group (#1568)
* net: a few small cleanups before replacing boost threads

- Drop the interruption point directly after the pnode allocation. This would
    be leaky if hit.
- Rearrange thread creation so that the socket handler comes first

* net: add CThreadInterrupt and InterruptibleSleep

* net: make net interruptible

Also now that net threads are interruptible, switch them to use std
threads/binds/mutexes/condvars.

* net: make net processing interruptible

* net: remove thread_interrupted catch

This is now a std::thread, so there's no hope of catching a boost interruption
point.

* net: make proxy receives interruptible

* net: misc header cleanups

8f4e67f152 net: Automatically create hidden service, listen on Tor
Starting with Tor version 0.2.7.1 it is possible, through Tor's control socket
API, to create and destroy 'ephemeral' hidden services programmatically.
https://stem.torproject.org/api/control.html#stem.control.Controller.create_ephemeral_hidden_service

This means that if Tor is running (and proper authorization is available),
bitcoin automatically creates a hidden service to listen on, without user
manual configuration. This will positively affect the number of available
.onion nodes.

- When the node is started, connect to Tor through control socket
- Send `ADD_ONION` command
- First time:
    - Make it create a hidden service key
    - Save the key in the data directory for later usage
- Make it redirect port 8333 to the local port 8333 (or whatever port we're listening on).
- Keep control socket connection open for as long node is running. The hidden service will
  (by default) automatically go away when the connection is closed.

67a7949397 privacy: Stream isolation for Tor
According to Tor's extensions to the SOCKS protocol
(https://gitweb.torproject.org/torspec.git/tree/socks-extensions.txt)
it is possible to perform stream isolation by providing authentication
to the proxy. Each set of credentials will create a new circuit,
which makes it harder to correlate connections.

This patch adds an option, `-proxyrandomize` (on by default) that randomizes
credentials for every outgoing connection, thus creating a new circuit.

aac3205375 src/netbase.h: Fix endian in CNetAddr serialization
We've chosen to htons/ntohs explicitly on reading and writing
(I do not know why). But as READWRITE already does an endian swap
on big endian, this means the port number gets switched around,
which was what we were trying to avoid in the first place. So
to make this compatible, serialize it as FLATDATA.

84881f8c47 rework overhauled serialization methods to non-static
Thanks to Pieter Wuille for most of the work on this commit.
I did not fixup the overhaul commit, because a rebase conflicted
with "remove fields of ser_streamplaceholder".
I prefer not to risk making a mistake while resolving it.

3d796f8996 overhaul serialization code
The implementation of each class' serialization/deserialization is no longer
passed within a macro. The implementation now lies within a template of form:

template <typename T, typename Stream, typename Operation>
inline static size_t SerializationOp(T thisPtr, Stream& s, Operation ser_action, int nType, int nVersion) {
    size_t nSerSize = 0;
    /* CODE */
    return nSerSize;
}

In cases when codepath should depend on whether or not we are just deserializing
(old fGetSize, fWrite, fRead flags) an additional clause can be used:
bool fRead = boost::is_same<Operation, CSerActionUnserialize>();

The IMPLEMENT_SERIALIZE macro will now be a freestanding clause added within
class' body (similiar to Qt's Q_OBJECT) to implement GetSerializeSize,
Serialize and Unserialize. These are now wrappers around
the "SerializationOp" template.

43f510d37d Convert closesocket 'compat wrapper' to function in netbase
Simpler alternative to #4348.

The current setup with closesocket() is strange. It poses
as a compatibility wrapper but adds functionality.

Rename it and make it a documented utility function in netbase.

Code movement only, zero effect on the functionality.

f3967bcc50 build: fix build weirdness after 54372482.
bitcoin-config.h moved, but the old file is likely to still exist when
reconfiguring or switching branches. This would've caused files to not rebuild
correctly, and other strange problems.

Make the path explicit so that the old one cannot be found.

Core libs use config/bitcoin-config.h.

Libs (like crypto) which don't want access to bitcoin's headers continue
to use -Iconfig and #include bitcoin-config.h.

e27c4110d9 Remove build-time no-IPv6 setting
The year is 2014. All supported operating systems have IPv6 support,
most certainly at build time (this doesn't mean that IPv6 is configured,
of course).

If noone is exercising the functionality to disable it, that means it
doesn't get tested, and IMO it's better to get rid of it.

(it's also not used consistently in RPC/boost and Net code...)
