[fpc-pascal] How to avoid namespace name clashes after USES ?

[Jorge Aldo G. de F. Junior]

Instead of implementing the half-assed C++ namespace model, just add
to the compiler a warning when it detects that there is a collision in
the current scope (two functions with the same parameters from
different units that can be called from the scope being inspected). I
believe function overload alread provides the necessary hooks, but i
cant do it because i have zero experience with FPC sources...
