Add support to makefile.unix for the same parameters used by bitcoin-qt.pro, dynamic linking unless STATIC=1 is passed

Bugfix: getmemorypool "bits" should be a hex-string

Unix build documentation improvements

Collate generic dependency information. Segregate distribution-specific (Ubuntu/Debian) information. Add Gentoo information.

Replaced all occurrences of #if* __WXMSW__ with WIN32,
and all occurrences of __WXMAC_OSX__ with MAC_OSX, and made
sure those are defined appropriately in the makefile and bitcoin-qt.pro.

Fix for win64 build

Remove 2 second sleep from CheckWork

Optimize HTTP status messages

remove code that reads addr.txt in LoadAddreses()

Bugfix: ThreadSocketHandler creation error

Only GetAdjustedTime once for the retry loop

Remove possibility of 63 bit overflow in ParseMoney

Added RPC call 'getmemorypool' for p2p mining pools

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.

- also, add unit tests for various functions in util.cpp/util.h
