Bug 13213 – Make 'go to definition' play nicer with extern(C)

In C/C++, there are 2 features, 'go to declaration' (ctrl-alt-F12) and 'go to definition' (F12), one generally takes you to the header file, the other takes you to the code. In VisualD, there only seems to be 'go to definition' (F12), this makes sense for D code, since there are no headers, but it's not so helpful with extern(C) functions. It is very common to have VisualD projects alongside C/C++ projects. Would it be possible to detect extern(C) functions, and make 'go to definition' go to the function definition in the C code instead of the D prototype? For completeness, it would be nice to offer 'go to declaration' (ctrl-alt-F12) also in these cases, which would go to the prototype in the D code, just like jumping to the header in C.

I added "Goto Declaration" and made "Goto Definition" check the Object Browser for forward declared symbols. This allows jumping to C/C++ code aswell (but not those C files that are part of the D project, because they don't appear in the object browser). See https://github.com/D-Programming-Language/visuald/releases/tag/v0.3.40-beta4

removing keyword "symdeb", this it not related to debug info.

Very awesome! I can confirm that it is working well. Thanks Rainer!
