Any problems seen during deserialization will throw an uncaught
exception, crashing the entire bitcoin process. Properly return an
error instead, so that we may at least log the error and gracefully
shutdown other portions of the app.
When a 0.6 wallet with compressed pubkeys is created, it writes a
minversion record to prevent older clients from reading it. If the 0.5
loading it sees a key record before seeing the minversion record however,
it will fail with DB_CORRUPT instead of DB_TOO_NEW.

-checkblocks now takes a numeric argument: the number of blocks that must
be verified at the end of the chain. Default is 2500, and 0 means all
blocks.
-checklevel specifies how thorough the verification must be:
0: only check whether the block exists on disk
1: verify block validity (default)
2: verify transaction index validity
3: check transaction hashes
4: check whether spent txouts were spent within the main chain
5: check whether all prevouts are marked spent
6: check whether spent txouts were spent by a valid transaction that consumes them
Before 0.6 addrProxy was a CAddress, but netbase changed it to CService.
Retain compatibility by wrapping/unwrapping with a CAddress when saving
or loading.
This commit retains compatibility with 0.6.0rc1 (which wrote the setting
as a CService) by trying to parse twice.
Design goals:
* Only keep a limited number of addresses around, so that addr.dat does not grow without bound.
* Keep the address tables in-memory, and occasionally write the table to addr.dat.
* Make sure no (localized) attacker can fill the entire table with his nodes/addresses.
See comments in addrman.h for more detailed information.
- icon from the LGPL Nuvola set (like the tick) - http://www.icon-king.com/projects/nuvola/
- include 'boost/version.hpp' in db.cpp so that the overwrite version of copy can be used
- catch exceptions in BackupWallet (e.g. filesystem_error thrown when trying to overwrite without the overwrite flag set)
- include db.h in walletmodel.cpp for BackupWallet function
- updated doc/assets-attribution.txt and contrib/debian/copyright with copyright info for new icon
This patch enabled compressed pubkeys when -compressedpubkeys is passed.
These are 33 bytes instead of 65, and require only marginally more CPU
power when verifying. Compressed pubkeys have a different corresponding
address, so it is determined at generation. When -compressedpubkeys is
given, all newly generated addresses will use a compressed key, while
older/other addresses keep using normal keys. Unpatched clients will
relay and verify these transactions.
so it takes a flag for how to interpret OP_EVAL.
Also increased IsStandard size of scriptSigs to 500 bytes, so
a 3-of-3 multisig transaction IsStandard.
OP_EVAL is a new opcode that evaluates an item on the stack as a script.
It enables a new type of bitcoin address that needs an arbitrarily
complex script to redeem.
