Convert observers to C++
This converts observers from using a special source-generating script to be plain C++. This version of the patch takes advantage of C++11 by using std::function and variadic templates; incorporates Pedro's patches; and renames the header file to "observable.h" (this change eliminates the need for a clean rebuild). Note that Pedro's patches used a template lambda in tui-hooks.c, but this failed to compile on some buildbot instances (presumably due to differing C++ versions); I replaced this with an ordinary template function. Regression tested on the buildbot. gdb/ChangeLog 2018-03-19 Pedro Alves <palves@redhat.com> Tom Tromey <tom@tromey.com> * unittests/observable-selftests.c: New file. * common/observable.h: New file. * observable.h: New file. * ada-lang.c, ada-tasks.c, agent.c, aix-thread.c, annotate.c, arm-tdep.c, auto-load.c, auxv.c, break-catch-syscall.c, breakpoint.c, bsd-uthread.c, cli/cli-interp.c, cli/cli-setshow.c, corefile.c, dummy-frame.c, event-loop.c, event-top.c, exec.c, extension.c, frame.c, gdbarch.c, guile/scm-breakpoint.c, infcall.c, infcmd.c, inferior.c, inflow.c, infrun.c, jit.c, linux-tdep.c, linux-thread-db.c, m68klinux-tdep.c, mi/mi-cmd-break.c, mi/mi-interp.c, mi/mi-main.c, objfiles.c, ppc-linux-nat.c, ppc-linux-tdep.c, printcmd.c, procfs.c, python/py-breakpoint.c, python/py-finishbreakpoint.c, python/py-inferior.c, python/py-unwind.c, ravenscar-thread.c, record-btrace.c, record-full.c, record.c, regcache.c, remote.c, riscv-tdep.c, sol-thread.c, solib-aix.c, solib-spu.c, solib.c, spu-multiarch.c, spu-tdep.c, stack.c, symfile-mem.c, symfile.c, symtab.c, thread.c, top.c, tracepoint.c, tui/tui-hooks.c, tui/tui-interp.c, valops.c: Update all users. * tui/tui-hooks.c (tui_bp_created_observer) (tui_bp_deleted_observer, tui_bp_modified_observer) (tui_inferior_exit_observer, tui_before_prompt_observer) (tui_normal_stop_observer, tui_register_changed_observer): Remove.
