b45c50ce51 Fix two problems in CSubNet parsing
Fix two CSubNet constructor problems:

- The use of `/x` where 8 does not divide x was broken, due to a
  bit-order issue

- The use of e.g. `1.2.3.4/24` where the netmasked bits in the network
  are not 0 was broken. Fix this by explicitly normalizing the netwok
  according to the bitmask.

Also add tests for these cases.

Fixes #6179. Thanks to @jonasschnelli for reporting and initial fix.

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.

35e408f8a4 Regard connection failures as attempt for addrman
This avoids connecting to them again too soon in ThreadOpenConnections.

Make an exception for connection failures to the proxy as these
shouldn't affect the status of specific nodes.

6050ab6855 netbase: Make SOCKS5 negotiation interruptible
Avoids that SOCKS5 negotiation will hold up the shutdown process.

- Sockets can stay in non-blocking mode, no need to switch it on/off
  anymore
- Adds a timeout (20 seconds) on SOCK5 negotiation. This should be
  enough for even Tor to get a connection to a hidden service, and
  avoids blocking the opencon thread indefinitely on a hanging proxy.

Fixes #2954.

ad49c256c3 Split up util.cpp/h
Split up util.cpp/h into:

- string utilities (hex, base32, base64): no internal dependencies, no dependency on boost (apart from foreach)
- money utilities (parsesmoney, formatmoney)
- time utilities (gettime*, sleep, format date):
- and the rest (logging, argument parsing, config file parsing)

The latter is basically the environment and OS handling,
and is stripped of all utility functions, so we may want to
rename it to something else than util.cpp/h for clarity (Matt suggested
osinterface).

Breaks dependency of sha256.cpp on all the things pulled in by util.

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.

caf6150e97 Use async name resolving to improve net thread responsiveness
In the LookupIntern(), things changed are:

  1. Call getaddrinfo_a() instead of getaddrinfo() if available, the former is a sync version of the latter;
  2. Try using inet_pton()/inet_addr() to convert the input text to a network addr structure at first, if success the extra name resolving thread inside getaddrinfo_a() could be avoided;
  3.  An interruption point added in the waiting loop for return from getaddrinfo_a(), which completes the improve for thread responsiveness.

A easy way to see the effect is to kick off a 'bitcoind stop' immediately after 'bitcoind -daemon', before the change it would take several, or even tens of, minutes on a bad network situation to wait for the running bitcoind to exit, now it costs only seconds.

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...)
