Don't poll showmyip.com, it doesn't exist anymore
Fixes #4679.

This leaves us with only one candidate, checkip.dyndns.org.
GetMyExternalIP should be phased out as soon as possible.

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.

dc942e6f27 Introduce whitelisted peers.
This adds a -whitelist option to specify subnet ranges from which peers
that connect are whitelisted. In addition, there is a -whitebind option
which works like -bind, except peers connecting to it are also
whitelisted (allowing a separate listen port for trusted connections).

Being whitelisted has two effects (for now):
* They are immune to DoS disconnection/banning.
* Transactions they broadcast (which are valid) are always relayed,
  even if they were already in the mempool. This means that a node
  can function as a gateway for a local network, and that rebroadcasts
  from the local network will work as expected.

Whitelisting replaces the magic exemption localhost had for DoS
disconnection (local addresses are still never banned, though), which
implied hidden service connects (from a localhost Tor node) were
incorrectly immune to DoS disconnection as well. This old
behaviour is removed for that reason, but can be restored using
-whitelist=127.0.0.1 or -whitelist=::1 can be specified. -whitebind
is safer to use in case non-trusted localhost connections are expected
(like hidden services).

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.

09a54a65c0 Use pnode->nLastRecv as sync score directly
NodeSyncScore() should find the node which we recv data most recently, so put a negative sign to pnode->nLastRecv is indeed wrong.

Also change the return value type to int64_t.

d387b8ec15 rpc: add getblockchaininfo and getnetworkinfo
Adds two new info query commands that take over information from
hodge-podge `getinfo`.

Also some new information is added:
- `getblockchaininfo`
  - `chain`: (string) current chain (main, testnet3, regtest)
  - `verificationprogress: (numeric) estimated verification progress
  - `chainwork`
- `getnetworkinfo`
  - `localaddresses`: (array) local addresses, from mapLocalHost (fixes #1734)

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...)

d20791b0e5 Prevent socket leak in ThreadSocketHandler.
When we are over our outbound limit ThreadSocketHandler would try to
 keep the connection if the peer was addnoded.

This didn't actually work for two reasons: It didn't actually run
 the accept code due to mistaken code flow, and because we have a
 limited number of outbound semaphores it couldn't actually use the
 connection.

Instead it leaked the socket, which might have caused issue #4034.

This patch just takes out the non-functioning white-listing for now.

094eeff0ba Bitcoin is running fine...
When bitcoind can't bind, bitcoin server (or Bitcoin Core Daemon) is probably already running. Add the missing word "server". Bitcoin itself is definitely running ;-)

Add _(...) so the string can be localized.

I apologize for such trivial changes, learning github interface.

f48742c2bf Get rid of C99 PRI?64 usage in source files
Amend to d5f1e72. It turns out that BerkelyDB was including inttypes.h
indirectly, so we cannot fix this with just macros.

Trivial commit: apply the following script to all .cpp and .h files:

    # Middle
    sed -i 's/"PRIx64"/x/g' "$1"
    sed -i 's/"PRIu64"/u/g' "$1"
    sed -i 's/"PRId64"/d/g' "$1"
    # Initial
    sed -i 's/PRIx64"/"x/g' "$1"
    sed -i 's/PRIu64"/"u/g' "$1"
    sed -i 's/PRId64"/"d/g' "$1"
    # Trailing
    sed -i 's/"PRIx64/x"/g' "$1"
    sed -i 's/"PRIu64/u"/g' "$1"
    sed -i 's/"PRId64/d"/g' "$1"

After this commit, `git grep` for PRI.64 should turn up nothing except
the defines in util.h.
