Fix Blockchain::get_tail_id() to set parameter to last block number instead of height
This reflects the behavior of blockchain_storage::get_tail_id().

Fixes #27 so that RPC method getlastblockheader works.

Add compile-time support for both db implementations: in-memory and LMDB
Usage:

default is lmdb for blockchain branch:
$ make release

same as:
$ DATABASE=lmdb make release

for original in-memory implementation:
$ DATABASE=memory make release

Fix seed node threaded DNS lookup
Use copied value of seed node index during thread creation, not
reference.
- fixes segfault

Use boost:🧵:try_join_until() instead of an atomic flag result
variable for each thread.

Add and handle interrupt for thread timeout.
- fixes segfault where a thread exceeds requested timeout and tries to
  assign results to a referenced, but now out-of-scope, variable in
  the main thread.

Fix height assertion in Blockchain::handle_alternative_block()
It expects the total number of blocks of main chain, not last block id
(off-by-one error).

This again behaves like the same height assertion done in original
implementation in blockchain_storage::handle_alternative_block().

This allows a reorganization to proceed after an alternative block has
been added.

Fix comparison between main and alternate chain's cumulative
difficulty.

This fixes the continual reorganization between a main and alternate
chain, using the same two latest blocks from each.

The check that cumulative difficulty of the alternate chain is bigger
than main's was not using main's last block, but incorrectly using the
passed-in block's previous block. main_chain_cumulative_difficulty was
being used in two different ways. This has been split up to keep use
of main_chain_cumulative_difficulty consistent.

Remove a have_block() check so alternate block can be processed
Remove have_block() check from Blockchain::handle_block_to_main_chain().
Add logging to have_block().

This allows blockchain reorganization to proceed further.

have_block() check here causes an error after a blockchain reorganize
begins with error: "Attempting to add block to main chain, but it's
already either there or in an alternate chain."

While reorganizing to become the main chain, a block in the
alternative chain would be refused due to have_block() rightfully
finding it in the alternative chain. The reorganization would end in
rollback, restoring to previous blockchain.

Original implementation didn't call it here, and it doesn't appear
necessary to be called from here in this implementation either. When
needed, it appears it's called prior to handle_block_to_main_chain().

Complete implementation of transaction removal
Complete method BlockchainLMDB::remove_output()
  - use output index as the key for:
    m_output_indices, m_output_txs, m_output_keys
  - call new method BlockchainLMDB::remove_amount_output_index()

Add method to remove amount output index.
  - BlockchainLMDB::remove_amount_output_index()
  - for m_output_amounts

This also fixes the segfault when blockchain reorganization is
attempted.

Fix transfers to support mixins
Implement BlockchainLMDB::get_output_global_index()
- returns global output index for a given amount and amount output
  index.

Add information to debug statement for failed ring signature check
within Blockchain::check_tx_inputs()

Fixes bitmonerod RPC call "/getrandom_outs.bin" to return correct
output keys, used in creating a transaction with mixins.

TODO: get_output_global_index() could be refactored with part of
get_output_tx_and_index() as the latter uses the former's
functionality.  Keep track of LMDB read transaction.

Fix transfers (without mixins)
Fix Blockchain::get_tx_outputs_gindexs() to return amount output
indices.

Implement BlockchainLMDB::get_tx_amount_output_indices() and call it
from the function instead of BlockchainLMDB::get_tx_output_indices()

Previously, Blockchain::get_tx_outputs_gindexs() was instead returning
global output indices, which are internal to LMDB databases.

Allows bitmonerod RPC /get_o_indexes.bin to return the amount output
indices as expected.

Allows simplewallet refresh to set correct amount output indices for
incoming transfers. simplewallet can now construct and send valid
transactions (currently only without mixins).

This is a fix that doesn't require altering the structure of the
current LMDB databases.

TODO:

This can be done more efficiently by adding another LMDB database
(key-value table).

It's not used during regular transaction validation by bitmonerod. I
think it's currently used only or mainly by simplewallet for just its
own incoming transactions. So the current behavior is not a primary
bottleneck.

Currently, it's using the "output_amounts" database, walking through a
given amount's list of values, comparing each one to a given global
output index. The iteration number of the match is the desired result:
the amount output index. This is done for each global output index of
the transaction.

A tx's amount output indices can be stored in various other ways
allowing for faster lookup. Since a tx is only written once, there are
no special future write requirements for its list of indices.

throw inline functions need to keep exception type
As it is useful for functions calling BlockchainDB functions to know
whether an exception is expected (attempting to get a block that doesn't
    exist and counting it missing if not, to save time checking if it
    does, for example), the inline functions throw{0,1} need to keep the
exception type information.

Slight comment update due to copy/paste failure.
