move probes to be per-bfd
This patch moves the probe data from the objfile to the per-BFD object. This lets the probes be shared between different inferiors (and different objfiles when dlmopen is in use, should gdb ever handle that). 2014-03-03 Tom Tromey <tromey@redhat.com> * elfread.c (probe_key): Change to bfd_data. (elf_get_probes, probe_key_free, _initialize_elfread): Probes are now per-BFD, not per-objfile. * stap-probe.c (stap_probe_destroy): Update comment. (handle_stap_probe): Allocate on the per-BFD obstack.
