typedef std::vector<unsigned char>.

Introduce a typedef for std::vector<unsigned char> to simplify life in
the future.
Implement name_pending RPC call.

Add a new RPC call "name_pending" that lists all pending name operations
in the memory pool together with some decoded information (operation
performed and value the name is set to).
Enforce minimum fee for name_update.

Add a mandatory minimum fee for name_update transactions.  Below this
fee, no transactions will be accepted to the memory pool (but they
remain valid).
Don't ask for fee with name_update's.

Reduce debug message for async RPC call threads when no threads
Compile with DEBUG_LOCKORDER to detect inconsistent lock orderings that can cause deadlocks

Backported from bitcoin commit 865ed8a1e5c587468a40756d46bcbc1c5a12bb06
Fix to remain compatible with DEBUG_LOCKORDER
Fix rpc-hanging deadlocks

Collapsed multiple wallet mutexes to a single cs_wallet, to avoid deadlocks with wallet methods that acquired locks in different order.
Also change master RPC call handler to acquire cs_main and cs_wallet locks before executing RPC calls; requiring each RPC call to acquire the right set of locks in the right order was too error-prone.

Changed semantics of CWalletTx::GetTxTime(); now always returns the time the transaction was received by this node, not the average block time.

Fix some address-handling deadlocks

Made three critical blocks for cs_mapAddresses smaller, and moved
writing to the database out of them. This should also improve the
concurrency of the code.
