Very much work in progress, not in a particularly working state. Haiku munged

a good part of the source tree, so I rather get those changes into the
repository before continuing.
The general aim of the work is to deal with multiple instances of the same
function, e.g. inlined or non-inlined inline functions or those weird duplicates
gcc (4 at least) seems to be generating for no apparent reason.
* Added classes FunctionInstance (wrapping FunctionDebugInfo) and Function.
  FunctionInstance represents a physical instance of a function (e.g. inlined
  function at a particular address). A Function collects all FunctionInstances
  referring to the same source code location.
* Moved the SourceCode property from FunctionDebugInfo to Function accordingly.
* Since SourceCode is no longer associated with a concrete function instance,
  several methods dealing with statements have been removed and the
  functionality has been provided through other means (e.g. TeamDebugModel or
  SpecificImageDebugModel). This part is not yet completed.
* Introduced UserBreakpoint and UserBreakpointInstance. The user sets a
  breakpoint at a source code location, which is represented by a
  UserBreakpoint. Since that source location can be mapped to one address per
  instance of the respective function, UserBreakpoint has a
  UserBreakpointInstance per such function instance, which in turn refers to a
  Breakpoint (an actual breakpoint at an address).
* Adjusted Breakpoint, BreakpointManager, and TeamDebugger accordingly.
