Decompilation of object or rebased files

[PeterMatula]

Decompilation via RetDec idaplugin gets into troubles if IDA has the file mapped on a different address than RetDec. In such a case, all metadata that come from IDA in config database are wrong when applied on image loaded by RetDec's image loader library.

This happens for object files. E.g. hello.zip, where IDA has main() on address 0x8000000 and RetDec has it on 0x34.

The same thing happens if user makes a rebase in IDA. E.g. here mytest.zip, main() is at 0x8900180, but in IDA, we can do Edit→Segments→Rebase program to 0x1000000 and run decompilation.

Solution: Probably get segments mappings from IDA and apply them in RetDec. This might be tricky, since RetDec libraries are probably not ready for it.
