Change some internal data structures to keep track of spentness of each wallet transaction output separately, to support partially-spent transactions:
* an update to the data structures (vfSpent in CWalletTx instead of fSpent)
* a backward-compatible update to the wallet disk format. Old clients reading back an updated wallet will ignore partially spent transactions when creating new ones, and may report a wrong balance, though.
* some helper functions (CWalletTx: IsSpent, MarkSpent, MarkDirty to reset cached values, GetAvailableCredit which only counts unredeemed outputs)
SendMoney*() now requires caller to acquire cs_main.
GetAccountAddress() now requires caller to acquire cs_main, cs_mapWallet.
Ordering is intended to match these two callchains[1]:
1. CRITICAL_BLOCK(cs_main)
ProcessMessage(pfrom, strCommand, vMsg)
AddToWalletIfMine()
AddToWallet(wtx)
CRITICAL_BLOCK(cs_mapWallet)
2. CRITICAL_BLOCK(cs_main)
ProcessMessage(pfrom, strCommand, vMsg)
AddToWalletIfMine()
AddToWallet(wtx)
CRITICAL_BLOCK(cs_mapWallet)
walletdb.WriteName(PubKeyToAddress(vchDefaultKey), "")
CRITICAL_BLOCK(cs_mapAddressBook)

Changed algorithm to use continuous exponential function instead of discrete 10-minute window.
Changed -limitfreerelay to be kilobytes-per-minute instead of boolean.
