* debug.c (debug_set_state, debug_restore_state): New functions.
* debug.h (debug_state_t): New type.
(debug_set_state, debug_restore_state): Declared, and defined
as dummy macros in non-debug-support build.
* lisplib.c (opt_dbg_autoload): New global variable.
(lisplib_try_load): Disable or enable debugging around
library loading based on opt_dbg_autoload option.
* lisplib.h (opt_dbg_autoload): Declared.
* txr.c (help): List --debug-autoload option.
(no_dbg_support): New static function to avoid repeated code.
(txr_main): Add debugger option. Change duplicate no debug support
error messages into calls to no_dbg_support.

This speeds up the TXR Lisp interpreter, because do_eval
sets up a debug frame and uses debug_return.
* debug.c (debug_block_s): Symbol removed.
(debug_init): Remove initialization of debug_block_s.
* debug.h (debug_block_s): Declaration removed.
(debug_enter): Do not establish a named block or a catch block;
no time-wasting unwind stack manipulation at all.
The debug_depth variable is managed by the extended setjmp
context now. Provide a return value variable, and a well-defined name to
branch to to exit from the debug block.
(debug_return): Do not use heavy-weight uw_block_return;
simply set the return variable and branch to debug_return_out
label.
* signal.h (EJ_DBG_MEMB, EJ_DBG_SAVE, EJ_DBG_REST,
EJ_OPT_MEMB, EJ_OPT_SAVE, EJ_OPT_REST): New macros.
(extended_jmp_buf): Define optional global state
variables using EJ_OPT_MEMB.
(extended_setjmp): Save and restore optional
globals using EJ_OPT_SAVE and EJ_OPT_RESTORE.
Now debug_depth is saved and restored if
debugging support is compiled in.
* match.c (open_data_source): Remove bogus debug_return
invocations which were uncovered here by changes to the macro.
* eval.c (do_eval, expand_macro): debug_return must now be after
debug_end, because it won't dynamically clean up frames that it doesn't
know about. The set_dyn_env is no longer unreachable in expand_macro;
it is now necessary because debug_return isn't doing the longjmp
that previously restored dyn_env.

(debug): In backtrace, show the renaming pairs for unbound
variables (up_p_a_pairs) if they are present.
* debug.h (debug_begin): Renamed to debug_frame.
* eval.c (eval): Wrap debug_begin/debug_end around function dispatch,
so TXR Lisp functions are included in backtraces.
