Data should be removed in the reverse order it was added. Not doing so
breaks assumptions and can cause problems in other DB implementations.
This matches the order of tx removal in
blockchain_storage::purge_block_data_from_blockchain.
This improves blockchain reorganization time by allowing one of the more
expensive DB lookups when popping a block to not have to seek through a
long dup list in the "output_amounts" subdb. This is most noticeable for
HDDs.
As before, the dup list is still walked if necessary (but in reverse),
and the global output index still confirmed to be the one looked for.
But under proper use, the result will be found at the end of the dup
list, so we start there.
Removing an amount output index is always done in the context of popping
a block, so the global output index being looked for should be the last
one in that amount key's dup list. Even if the txs themselves aren't
removed in reverse order (supposed to be according to original
implementation), the specified amount output index will still be near
the end, because the txs are in the same block.
TEST:
Pop blocks with blockchain_import.
Blocks should be successfully removed with no errors shown.
bitmonerod should be able to start syncing from the reduced blockchain
height.

In particular, <boost/program_options.hpp> blows up daemon.cpp.obj,
making it too big to compile in debug mode on Win32. Even on a
release build it drops daemon.cpp.o on Linux from 31MB to 20MB.
This has no effect on the final linked binary size.
The version number passed to those data's serialize function
was always 0, not the wallet's version as I had expected.
A version number now exists for these structures so they're
versioned correctly.

Sample use:
DNS_PUBLIC=tcp torsocks bin/bitmonerod --p2p-bind-ip 127.0.0.1
Test:
Run above with --log-level 4 with and without DNS_PUBLIC environment
variable set.
DNS debugging info should show successful DNS lookups only when
DNS_PUBLIC is set to "tcp":
DNS lookup for seeds.moneroseeds.se: 17 results
DNS lookup for seeds.moneroseeds.ae.org: 17 results
DNS lookup for seeds.moneroseeds.ch: 12 results

This prevents the intermediate thread from exiting properly, as
fork creates a child process with only one thread, so any existing
data_logger thread will not be in the child. Since this thread
sets a flag the data_logger dtor blocks on, all children threads
will hang on exit.
When throwing an exception from being unable to begin an LMDB
transaction, include the reason.
It's often been due to a write transaction attempted within a write
transaction (batch mode), but there can be other reasons such as write
transaction attempted while database was opened read only, or
environment's map needs to be resized.
The core tests use the blockchain, and reset it to be able
to add test data to it. This does not play nice with the
databases, since those will save that data without an explicit
save call.
We add a fakechain flag that the tests will set, which tells
the core and blockchain code to use a separate database, as
well as skip a few things like checkpoints and fixup, which
only make sense for real data.
Data is only guaranteed to be valid within the lifetime of a txn.
You cannot use data returned from LMDB after the txn ends.
Also, fixed a missing txn.commit BlockchainLMDB::get_tx_unlock_time()
This fixes coretests, which does not register daemon specific arguments,
but uses core, which uses those arguments. Also gets rid of an unwanted
dependency on daemon code from core.
This is a precaution for older Berkeley DB versions.
- smooth reports an issue running with 4.7:
DB_ENV->log_set_config: DB_LOG_IN_MEMORY: method not permitted
after handle's open method
- this works just fine with 5.3
- we do not use DB_LOG_IN_MEMORY, but we use DB_LOG_AUTO_REMOVE
- libdb docs say some flags must be set before open, and some
may be set at any time, but never say some must be set after
open
- moving the call to log_set_config before open works with 5.3
Therefore, it seems best to move the call before open.
Early DB versions did not store key images for inputs if the
transaction spending them had no outputs (ie, all fee). This
is not correct, as this would allow these outputs to be double
spent. This was fixed in 533acc30ed
a few months ago, but databases having synced blocks 2021612 and
685498 with a faulty version will be missing those key images
in the spent keys database. This code checks for this, and adds
those key images if they are missing.
Berkeley DB uses 1 based indices for RECNO databases, and the
implementation of BlockchainDB for Berkeley DB assumes 1 based
indices are passed to the API, whereas the LMDB one assumes
0 based indices. This is all internally consisteny, but since
the BDB code stores 1 based indices in the database, external
users have to be aware of this, as the indices will be off by
one depending on which DB is used.
^C while in manual refresh will cancel the refresh, since that's
often an annoying thing to have to wait for. Also, a manual refresh
command will interrupt any running background refresh and take
over, rather than wait for the background refresh to be done, and
look to be hanging.

The daemon will be polled every 90 seconds for new blocks.
It is enabled by default, and can be turned on/off with
set auto-refresh 1 and set auto-refresh 0 in the wallet.
This allows them to be saved as a fixed (one byte) chunk whatever
the value. Using a varint will use two bytes as the high bit gets
set.
This is backward compatible with current usage (0-2 values).
