Use block index when obtaining block's difficulty for log statement
Use last block id, not number of blocks (off-by-one error).

Fixes error at start of blockchain reorganization: "Attempt to get
cumulative difficulty from height <XXXXXX> failed -- difficulty not in
db"

Add a --restricted-rpc flag to simplewallet
It restricts RPC to a subset of "view only" commands. Kind of like
a poor man's view key replacement.

Fix transfers

Output indexing was being handled improperly.  These changes fix that.  Wallets (re-)created using this branch will need to be (re-)re-created in order to get correct output indices.

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.

Fixes problem of obtaining incorrect outputs used for tx input.

10fd6cab6c blockchain_db: factor some exception code
Ideally, the log would go in the exception's ctor, but
two log levels are used, so I'd need to specify the level
in the ctor, which isn't great as it's not really related
to the exception.
