6853e627f1 Fix build on windows and mac
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.

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.

507fd9d15b Start moving protocol-specific code to protocol.[ch]pp
Move CMessageHeader from net.h to protocol.[ch]pp, with the
implementation in the .cpp compilation unit (compiling once is enough).

This commit does *not* and should not modify *any* code, it only moves
it from net.h and splits it across protocol.cpp and protocol.hpp.

Indentation changes aside the closest thing to a modification of code is
the addition of the 'TODO' comment (the execution of which requires code
modifications and thus doesn't belong in this commit).

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.

03fbd79049 get rid of mapPubKeys
Make CKeyStore's interface work on uint160's instead of pubkeys, so
no separate global mapPubKeys is necessary anymore.

7414733bea Make an invalid addrIncoming so that old clients crash.
This prevents old clients from opening, and thus corrupting
or otherwise causing harm to encrypted wallets.

64c7ee7e6b CWallet class
* A new class CKeyStore manages private keys, and script.cpp depends on access to CKeyStore.
* A new class CWallet extends CKeyStore, and contains all former wallet-specific globals; CWallet depends on script.cpp, not the other way around.
* Wallet-specific functions in CTransaction/CTxIn/CTxOut (GetDebit, GetCredit, GetChange, IsMine, IsFromMe), are moved to CWallet, taking their former 'this' argument as an explicit parameter
* CWalletTx objects know which CWallet they belong to, for convenience, so they have their own direct (and caching) GetDebit/... functions.
* Some code was moved from CWalletDB to CWallet, such as handling of reserve keys.
* Main.cpp keeps a set of all 'registered' wallets, which should be informed about updates to the block chain, and does not have any notion about any 'main' wallet. Function in main.cpp that require a wallet (such as GenerateCoins), take an explicit CWallet* argument.
* The actual CWallet instance used by the application is defined in init.cpp as "CWallet* pwalletMain". rpc.cpp and ui.cpp use this variable.
* Functions in main.cpp and db.cpp that are not used by other modules are marked static.
* The code for handling the 'submitorder' message is removed, as it not really compatible with the idea that a node is independent from the wallet(s) connected to it, and obsolete anyway.

e89b9f6a2a move wallet code to separate file
This introduces two new source files, keystore.cpp and wallet.cpp with
corresponding headers. Code is moved from main and db, in a preparation
for a follow-up commit which introduces the classes CWallet and CKeyStore.

76d660ebd3 Faster timeout when connecting
Use non-blocking connects, and a select() call to wait a predefined
time (5s by default, but configurable with -timeout) for either
success or failure. This allows much more connections to be tried
per time unit.

Based on a patch by phantomcircuit.

2bfda1be11 Separate required fee for relaying and creation
Transactions created with the new minimal fee policy would not be
relayed by the network. Therefore, we separate the minimal fee that
is necessary to relay and to create, leaving the creation one at
the old amount, for now.

1c528eeee9 Update transactions already in the wallet when rescanning.
When rescanning, if the scanned transaction is already in the wallet, it
is skipped. However, if someone sends a transaction, does not wait for
confirmation, switches wallets, waits for a block that contains his original
transaction, and switches wallets again, a rescan will leave his wallet
transaction (which has no merkle branch, so no confirmations) untouched.

84c3fb07b0 directory re-organization (keeps the old build system)
there is no internal modification of any file in this commit

files are moved into directories according to established standards in
sourcecode distribution; these directories contain:

 src - Files that are used in constructing the executable binaries,
       but are not installed.

 doc - Files in HTML and text format that document usage, quirks of
       the implementation, and contributor checklists.

 locale - Files that contain human language translation of strings
          used in the program

 contrib - Files contributed from distributions or other third party
 	   implementing scripts and auxiliary programs
