Tom Tromey f330038710 use explicit returns to avoid checker confusion
The checker does not understand the idiom

if (except.reason < 0) {
   do_cleanups (whatever);
   GDB_PY_HANDLE_EXCEPTION (except);
}

because it doesn't realize that the nested 'if' actually has the same
condition.

This fixes instances of this to be more explicit.

	* python/py-breakpoint.c (bppy_get_commands): Use
	explicit, unconditional return.
	* python/py-frame.c (frapy_read_var): Likewise.

Pedro Alves a6e6f79133 Fix build breakage with Python 2.4.
With Python 2.4, we see this build failure:

./python/python-internal.h: In function 'gdb_Py_DECREF':
./python/python-internal.h:179: warning: dereferencing 'void *' pointer
./python/python-internal.h:179: error: request for member 'ob_refcnt' in something not a structure or union

Python 2.4 forgets to cast 'op' to PyObject pointer on the ob_refcnt
accesses:

  #define Py_DECREF(op)                                   \
          if (_Py_DEC_REFTOTAL  _Py_REF_DEBUG_COMMA       \
              --(op)->ob_refcnt != 0)                     \
                  _Py_CHECK_REFCNT(op)                    \
          else                                            \
                  _Py_Dealloc((PyObject *)(op))

...

  #define _Py_CHECK_REFCNT(OP)                                    \
  {       if ((OP)->ob_refcnt < 0)                                \
                  _Py_NegativeRefcount(__FILE__, __LINE__,        \
                                       (PyObject *)(OP));         \
  }

Python 2.7:

  #define Py_DECREF(op)                                   \
      do {                                                \
          if (_Py_DEC_REFTOTAL  _Py_REF_DEBUG_COMMA       \
          --((PyObject*)(op))->ob_refcnt != 0)            \
              _Py_CHECK_REFCNT(op)                        \
          else                                            \
          _Py_Dealloc((PyObject *)(op));                  \
      } while (0)

...

  #define _Py_CHECK_REFCNT(OP)                                    \
  {       if (((PyObject*)OP)->ob_refcnt < 0)                             \
                  _Py_NegativeRefcount(__FILE__, __LINE__,        \
                                       (PyObject *)(OP));         \

Pedro Alves ac90359cdc Let the ARI know gdb_Py_DECREF is OK.
The ARI complains with:

> gdb/python/python-internal.h:177: code: editCase function: Function name starts lower case but has uppercased letters.
gdb/python/python-internal.h:177:gdb_Py_DECREF (void *op)

gdb_Py_DECREF is just wrapping a python macro that happens to be mixed case.

	* python/python-internal.h (gdb_Py_DECREF): Tag with
	"ARI: editCase function".

Pedro Alves c8c735b963 py_decref: Don't check for NULL before calling Py_DECREF.
The only difference between Py_DECREF and Py_XDECREF is that the latter allows passing
in a NULL object, while the former prohibits it.  Given that, it's natural to expect
the same from py_decref vs py_xdecref.

Pedro Alves 1915daebe6 Centralize workaround for Python 2.6's Py_DECREF.
Wrap/redefine Py_DECREF ourselves, avoiding the need for uses to care
about extra braces due to the fact that Python only started wrapping Py_DECREF
in 'do {} while (0)' after 2.6.

Pedro Alves 6f937416b9 Constify strings in tracepoint.c, lookup_cmd and the completers.
This is sort of a continuation of Keith's parse_exp_1 constification
patch.  It started out by undoing these bits:

  @@ -754,9 +754,12 @@ validate_actionline (char **line, struct
   	  tmp_p = p;
   	  for (loc = t->base.loc; loc; loc = loc->next)
   	    {
  -	      p = tmp_p;
  -	      exp = parse_exp_1 (&p, loc->address,
  +	      const char *q;
  +
  +	      q = tmp_p;
  +	      exp = parse_exp_1 (&q, loc->address,
   				 block_for_pc (loc->address), 1);
  +	      p = (char *) q;

and progressively making more things const upwards, fixing fallout,
rinse repeat, until GDB built again (--enable-targets=all).

That ended up constifying lookup_cmd/add_cmd and (lots of) friends,
and the completers.

I didn't try to constify the command hooks themselves, because I know
upfront there are commands that write to the command string argument,
and I think I managed to stop at a nice non-hacky split point already.

I think the only non-really-super-obvious changes are
tracepoint.c:validate_actionline, and tracepoint.c:trace_dump_actions.

The rest is just mostly about 'char *' => 'const char *', 'char **'=>
'const char **', and the occasional (e.g., deprecated_cmd_warning)
case of 'char **'=> 'const char *', where/when I noticed that nothing
actually cares about the pointer to pointer output.

Tested on x86_64 Fedora 17, native and gdbserver.
