[Bug python/12368] New: need more is_valid methods

           Summary: need more is_valid methods
           Product: gdb
           Version: HEAD
            Status: NEW
          Severity: normal
          Priority: P2
         Component: python
        AssignedTo: unassigned@sourceware.org
        ReportedBy: tromey@redhat.com


Many objects exposed to python have independent lifetimes in gdb.
I think all such objects should have "is_valid" methods, so user
code can determine whether the object is valid or not.

At least blocks, block iterators, breakpoints, inferiors,
threads, objfiles, symbols, and symtabs need this treatment.
