* Fix wrong thread name for wallet *relocking* thread
- Was named the unlocking thread
* Use consistent naming

NOTE: These thread names are visible in gdb when using 'info threads'.
Additionally both 'top' and 'ps' show these names *unless* told to
display the command-line instead of task name.

Adds CBlock::CURRENT_VERSION and CTransaction::CURRENT_VERSION
constants, and makes non-CURRENT_VERSION transactions nonstandard.
This will help make future upgrades smoother.
Prior to this change, each TX typically generated 3+ debug messages,
askfor tx 8644cc97480ba1537214 0
sending getdata: tx 8644cc97480ba1537214
askfor tx 8644cc97480ba1537214 1339640761000000
askfor tx 8644cc97480ba1537214 1339640881000000
CTxMemPool::accept() : accepted 8644cc9748 (poolsz 6857)
After this change, there is only one message for each valid TX received
CTxMemPool::accept() : accepted 22a73c5d8c (poolsz 42)
and two messages for each orphan tx received
ERROR: FetchInputs() : 673dc195aa mempool Tx prev not found 1e439346fc
stored orphan tx 673dc195aa (mapsz 19)
The -debugnet option, or its superset -debug, will restore the full debug
output.
- Signals now go directly from the core to WalletModel/ClientModel.
- WalletModel subscribes to signals on CWallet: Prepares for multi-wallet support, by no longer assuming an implicit global wallet.
- Gets rid of noui.cpp, the few lines that were left are merged into init.cpp
- Rename wxXXX message flags to MF_XXX, to make them UI indifferent.
- ThreadSafeMessageBox no longer returns the value `4` which was never used, converted to void.
Gets rid of `MainFrameRepaint` in favor of specific update functions that tell the UI exactly what changed.
This improves the efficiency of various handlers. Also fixes problems with mined transactions not showing up until restart.
The following notifications were added:
- `NotifyBlocksChanged`: Block chain changed
- `NotifyKeyStoreStatusChanged`: Wallet status (encrypted, locked) changed.
- `NotifyAddressBookChanged`: Address book entry changed.
- `NotifyTransactionChanged`: Wallet transaction added, removed or updated.
- `NotifyNumConnectionsChanged`: Number of connections changed.
- `NotifyAlertChanged`: New, updated or cancelled alert. As this finally makes it possible for the UI to know when a new alert arrived, it can be shown as OS notification.
These notifications could also be useful for RPC clients. However, currently, they are ignored in bitcoind (in noui.cpp).
Also brings back polling with timer for numBlocks in ClientModel. This value updates so frequently during initial download that the number of signals clogs the UI thread and causes heavy CPU usage. And after initial block download, the value changes so rarely that a delay of half a second until the UI updates is unnoticable.
If Reorganize() fails, then its caller, CBlock::SetBestChain(),
will call TxnAbort().
Redundant TxnAbort() calls are harmless. The second will return an
error return value, with no other side effects. TxnAbort() return
values are generally never checked. The impact is nil.
Loop over all inputs doing inexpensive validity checks first,
and then loop over them a second time doing expensive signature
checks. This helps prevent possible CPU exhaustion attacks
where an attacker tries to make a victim waste time checking
signatures for invalid transactions.
Remove orphan transactions from memory once
all of their parent transactions are received
and they're still not valid.
Thanks to Sergio Demian Lerner for suggesting this fix.
Old log message:

New log message:

Also, trim a few trailing whitespace in main.cpp.
Immediately issue a "getblocks", instead of a "getdata" (which will
trigger the relevant "inv" to be sent anyway), and only do so when
the previous set of invs led us into a known and attached part of
the block tree.
This prevents an undefined operation in main.cpp, when shifting the hash value
left by 32 bits.
Shifting a signed int left into the sign bit is undefined in C++11.
Introduce a boolean variable for each "network" (ipv4, ipv6, tor, i2p),
and track whether we are likely to able to connect to it. Addresses in
"addr" messages outside of our network get limited relaying and are not
stored in addrman.
This will make bitcoin relay valid routable IPv6 addresses, and when
USE_IPV6 is enabled, listen on IPv6 interfaces and attempt connections
to IPv6 addresses.
FetchInputs already logs failures internally. This commit makes the logging
more consistent with other FetchInputs callsites also.
Prior to this commit, two log lines were logged for one condition:
ERROR: FetchInputs() : de15fde415 mempool Tx prev not found a2c75da227
ERROR: CTxMemPool::accept() : FetchInputs failed de15fde415
After this commit, only one line is logged:
ERROR: FetchInputs() : e0507ab2c7 mempool Tx prev not found 9a620262cd
Previously, a single TX would trigger two log lines in quick succession,
addUnchecked(): size 152
CTxMemPool::accept() : accepted c4cfdd48b7
After this change, only one log line is used:
CTxMemPool::accept() : accepted 98885e65db (poolsz 26)
Pull request #948 introduced a fix for nodes stuck on a long side branch
of the main chain. The fix was non-functional however, as the additional
getdata request was created in a first step of processing, but dropped
in a second step as it was considered redundant. This commits fixes it
by sending the request directly.
