        * lib/gdb.exp (gdb_breakpoint): Add pending breakpoint
        support.
        * gdb.base/langs.exp: Fix test which attempts to create
        breakpoint on non-existent function to handle new pending
        support.
        * gdb.base/shlib-call.exp: Use gdb_breakpoint to set
        a breakpoint.
        * gdb.base/pending.exp: New test.
        * gdb.base/pending.c: New file.
        * gdb.base/pendshr.c: Ditto.
