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. git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@31447 a95241bf-73f2-0310-859d-f6bbb57e9c96
