074d584a04 Added RPC call 'getmemorypool' that provides everything needed to construct a block with a custom generation transaction and submit a solution 
getmemorypool [data]
If [data] is not specified, returns data needed to construct a block to work on:
  "version" : block version
  "previousblockhash" : hash of current highest block
  "transactions" : contents of non-coinbase transactions that should be included in the next block
  "coinbasevalue" : maximum allowable input to coinbase transaction, including the generation award and transaction fees
  "time" : timestamp appropriate for next block
  "bits" : compressed target of next block
If [data] is specified, tries to solve the block and returns true if it was successful.

6cc4a62c0e 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.

99860de3c9 Make some global variables less-global (static) 
Explicitly make these global variables less-global to reduce the maximum
scope of this global state.

In my experience global variables tend to be a major source of bugs. As
such the less accessible they are the less likely they are to be the
source of a bug.

25133bd74b Use 'unsigned char' rather than 'char' for pchMessageStart. 
Regarding https://bitcointalk.org/index.php?topic=28022.0

main.cpp has: "char pchMessageStart[4] = { 0xf9, 0xbe, 0xb4, 0xd9 };"
Per discussion on the thread linked, leaving the signedness of
pchMessageStart is unsafe for values > 0x80. This patch specifies
'unsigned char' in main.cpp and net.h.

643160f6e7 Actually use mapAlreadyAskedFor. 
Previously, mapAlreadyAskedFor was read from, but never added to.
The original intent was to use mapAlreadyAskedFor to keep track
of the time an item was requested and "Each retry is 2 minutes
after the last".
This implements that intent.

no separate global mapPubKeys is necessary anymore.
