On hosts that had spent some time with a failed internet connection their
nAttempts penalty was going through the roof (e.g. thousands for all peers)
and as a result the connect search was pegging the CPU and failing to get
more than a 4 connections after days of running (because it was taking so
long per try).

The environment is prepared by the main thread to guard against invalid locale settings and to prevent deinitialization issues of Boost path, which can result in app crashes.
The scope of `std::locale::global` appears to be smaller than `setenv("LC_ALL", ...)` and insufficient to fix messed up locale settings for the whole application.
Some tests in CheckBlockIndex require chainActive.Tip(), but when reindexing, chainActive has not been set on the first call to CheckBlockIndex.
reindex.py starts a node, mines 3 blocks, stops, and reindexes with CheckBlockIndex enabled.

This fixes a subtle bug involving block re-orgs and non-standard transactions.
Start with a block containing a non-standard transaction, and
one or more transactions spending it in the memory pool.
Then re-org away from that block to another chain that does
not contain the non-standard transaction.
Result before this fix: the dependent transactions get stuck
in the mempool without their parent, putting the mempool
in an inconsistent state.
Tested with a new unit test (adapted for 0.10).

To give the torrents (which use web seeds) better names, we updated the
URL scheme on bitcoin.org/bin. This updates the release notes and
release doc accordingly, plus updates some other details based on recent
changes to the site.

Give each address a single fixed location in the new and tried tables,
which become simple fixed-size arrays instead of sets and vectors.
This prevents attackers from having an advantages by inserting an
address multiple times.
This change was suggested as Countermeasure 1 in
Eclipse Attacks on Bitcoin’s Peer-to-Peer Network, Ethan Heilman,
Alison Kendler, Aviv Zohar, Sharon Goldberg. ePrint Archive Report

It is also more efficient.

This adds a -checkblockindex (defaulting to true for regtest), which occasionally
does a full consistency check for mapBlockIndex, setBlockIndexCandidates, chainActive, and
mapBlocksUnlinked.
The path locale is lazy initialized and to avoid deinitialization errors
in multithreading environments, it is set explicitly by the main thread.
