Fix compilation with clang under OS X

Removed a duplicated identical if

switch to Qt 4.8.2 for Windows builds

Update to use OpenSSL 1.0.1c

Remove stack randomization

walletdb.h: remove dead code

Fix: when testnet=1 specified, change default RPC port to 18332

As the code was before, toHTML added empty elements to mapValue to check for their existance. Now first it check for their existance and then for their non-emptiness.

Removed a duplicated identical if

There are two equal ifs, one inside another. If the first one is true, then the second one is true.

Documented bug in sign-extension behavior of opcodes OP_AND, OP_OR, and OP_XOR

Previously, trying to compile with clang would result in the error: assigning to 'objc_object *' from incompatible type 'DockIconClickEventHandler *'

commit 5a1a3622 effectively enabled these warnings, but they need
to be fixed before being enabled in the general build scripts.

Add printf-style warnings to strprintf() and OutputDebugStringF()

Due to a bug in the implementation of MakeSameSize(), using OP_AND, OP_OR, or OP_XOR with signed values of unequal size will result in the sign-value becoming part of the smaller integer, with nonsensical results. This patch documents the unexpected behavior and provides the basis of a solution should decision be made to fix the bug in the future.

Import $DataDir/bootstrap.dat automatically, if it exists.

Bitcoin-Qt: expand GCC Stack-Smashing Protector usage (non Windows)

additional fix for #1843

solution just a bit easier.

Update include for Qt5

Adds a stopdetach <detach> RPC command.  <detach> defaults to true.  Works just like stop, but overrides the commandline/config file
-detachdb option.  Useful for upgrading, for example.  Lets you use fast stops usually, but force a detach when needed.  Also, allows
you to do a fast stop in a system normally configured for fast stops.

Update Qmenu include

This is to be more consistent with the rest of the source

Update Qt Includes

Update links to Qt

This patch currently excludes our Windows executable!

- change to use -fstack-protector-all
- the minimum size of buffers (i.e. arrays) that will receive stack
  smashing protection was changed to 1 byte (GCC default: 8)
- warn about functions that will not be protected against stack
  smashing by adding -Wstack-protector

- a shortcut on "receive coins" was used twice
