Get rid of VEC(probe_p)
Replace the remaining usages of VEC(probe_p) with std::vector. Regtested on the buildbot. gdb/ChangeLog: * probe.h: Don't include gdb_vecs.h. (DEF_VEC_P (probe_p)): Remove. (find_probes_in_objfile): Return an std::vector. * probe.c (find_probes_in_objfile): Likewise. * breakpoint.c (breakpoint_objfile_data) <longjmp_probes>: Change type to std::vector. <exception_probes>: Likewise. (free_breakpoint_probes): Don't manually free vectors. (create_longjmp_master_breakpoint): Adjust. (create_exception_master_breakpoint): Adjust. * solib-svr4.c (svr4_create_probe_breakpoints): Change parameter type, adjust. (svr4_create_solib_event_breakpoints): Adjust.
