* RzBin/ELF: avoid the creation of useless flags at 0
Use UT64_MAX as an error value for addresses like symbols, imports,
sections, etc., and do not create flags for those because they are not
meaningful. This is useful for imports that do not have an address in
the virtual/file space and for non-alloc sections (e.g. .comment).
* Reduce recursion when analyzing function control-flow
* Jump table refactoring
* Use rz_ prefix for the API
* Use struct instead of long parameter list
* Add `analysis.jmp.tblmax` to configure maximun amount of cases to analyze
* Remove recursion
