* Added classes to represent source code (SourceCode, Statement).

* Added x86 disassembler (via libudis86).
* Added Architecture::DisassembleCode() to disassemble a function to SourceCode.
* Added virtual DebugInfo::LoadSourceCode() to retrieve the source code for a
  given function. The implementation in DebuggerDebugInfo disassembles the
  function.
* Added source code info to StackFrame. Also added a listener mechanism to get
  notified on source code changes.
* Added job to load the source code for a stack frame.
* Added (very basic) source code view and wired everything so that when a stack
  frame is selected the source code (respectively disassembly) for the
  underlying function is retrieved and shown.
