This commit adds method allowing one remove any objfile. This is meant to be used to remove objfiles for dynamic code when this dynamic code is discarded. However gdb.Objfile.unlink() makes no attempt to ensure this - to make it consistent with other Python API to create and modify objfiles related structures (compunits, symbol tables and so on).
