If we turn "remote debug" on and GDB does some vFile operations,
a lot of things will be printed in the screen, which makes
"remote debug" useless.
This patch changes the code that we only print 512 chars in max in
debugging messages, like this,

When I inspect the return values of disassmblers, I happen to see
various -1/-2/-3 magic numbers are used in m68k-dis.c. This patch
is to replace them with enum.
-1 and -2 is "clearly documented" in print_ins_arg's comments, but
-3 isn't. In fact, -3 is returned when FETCH_DATA returns false,
which means memory error (because fetch_data return 0 on memory
error). So I name enum PRINT_INSN_ARG_MEMORY_ERROR for -3.
This patch is a refactor patch, doesn't affect any functionality.

Disassemblers in opcodes return -1 on memory error, but msp430 doesn't

This replaces a cleanup in execute_gdb_command with an instance of
std::string.
Testing showed that this originally missed a cleanup that was returned
by prevent_dont_repeat. This version of the patch changes
prevent_dont_repeat to return a scoped_restore rather than a cleanup.

This changes dwarf2_evaluate_loc_desc_full to use scoped_value_mark.
Note that this function previously called do_cleanup using the same
cleanup multiple times. I had thought this was buggy, but re-reading
make_my_cleanup2 indicates that it is not. Nevertheless it is
surprising, and at least one of the calls (the one that is completely
removed in this patch) seems to have been done under the assumption
that it would still have some effect.

* dwarf2loc.c (dwarf2_evaluate_loc_desc_full): Use

This adds a scoped_value_mark class, that records the value mark in
the constructor and then calls value_free_to_mark in the destructor.
It then updates various spots in gdb to use this class, rather than a
cleanup.
It would be better overall to replace "struct value *" with a
shared_ptr, maybe eliminating the need for this class (watchpoints
would perhaps need some new mechanism as well). However, that's
difficult to do.

This introduces a new class, gdb::unlinker, that unlinks a file in the
destructor. The user of this class has the option to preserve the
file instead, by calling the "keep" method.
This patch then changes the spots in gdb that use unlink in a cleanup
to use this class instead. In one spot I went ahead and removed all
the cleanups from the function.
This fixes one latent bug -- do_bfd_delete_cleanup could refer to
freed memory, by decref'ing the BFD before using its filename.

This introduces a new specialization of gdb::ref_ptr that can be used
to manage BFD reference counts. Then it changes most places in gdb to
use this new class, rather than explicit reference-counting or
cleanups. This patch removes make_cleanup_bfd_unref.
If you look you will see a couple of spots using "release" where a use
of gdb_bfd_ref_ptr would be cleaner. These will be fixed in the next
patch.
I think this patch fixes some latent bugs. For example, it seems to
me that previously objfpy_add_separate_debug_file leaked a BFD.
I'm not 100% certain that the macho_symfile_read_all_oso change is
correct. The existing code here is hard for me to follow. One goal
of this sort of automated reference counting, though, is to make it
more difficult to make logic errors; so hopefully the code is clear
now.

This adds a new gdb_ref_ptr.h, that implements a reference-counting
smart pointer class, where the user of the class supplies a
reference-counting policy object.
This class will be used in the next patch, which changes most explicit
BFD reference counts to use this new type. Meanwhile, this patch
changes gdbpy_ref to be a specialization of this new class.
This change required adding new nullptr_t overloads some operators in
gdb_ref_ptr.h. I suspect this was needed because some Python header
redefines NULL, but I'm not certain.

gdbpy_ref.
This changes py-inferior.c to use gdbpy_ref in more places.
2017-01-10 Tom Tromey <tom@tromey.com>
* python/py-inferior.c (find_thread_object, build_inferior_list):
Use gdbpy_ref.
This changes py_print_frame to use gdbpy_ref in more places.
2017-01-10 Tom Tromey <tom@tromey.com>
* python/py-framefilter.c (py_print_frame): Use gdbpy_ref.
This changes bpfinishpy_out_of_scope to use gdbpy_ref.
2017-01-10 Tom Tromey <tom@tromey.com>
* python/py-finishbreakpoint.c (bpfinishpy_out_of_scope): Use
gdbpy_ref.
This changes py-cmd.c to use gdbpy_ref in more places. This also
fixes a latent memory leak in cmdpy_completer_helper, which
unnecessarily increfs the result of PyObject_CallMethodObjArgs. This
is not needed because that function returns a new reference.
2017-01-10 Tom Tromey <tom@tromey.com>
* python/py-cmd.c (cmdpy_completer_helper): Use gdbpy_ref. Remove
extra incref.
(cmdpy_completer_handle_brkchars, cmdpy_completer, cmdpy_init):
Use gdbpy_ref.
This changes gdbpy_breakpoint_cond_says_stop to use gdbpy_ref rather
than explicit reference management.
2017-01-10 Tom Tromey <tom@tromey.com>
* python/py-breakpoint.c (gdbpy_breakpoint_cond_says_stop): Use
gdbpy_ref.
This changes archpy_disassemble to use gdbpy_ref. It also fixes a
latent bug where archpy_disassemble was decref'ing the results of a
all to PyArg_ParseTupleAndKeywords. This is incorrect because
PyArg_ParseTupleAndKeywords returns borrowed references.
2017-01-10 Tom Tromey <tom@tromey.com>
* python/py-arch.c (archpy_disassemble): Use gdbpy_ref. Don't
decref results of PyArg_ParseTupleAndKeywords.
This changes python_run_simple_file to use gdbpy_ref and
unique_xmalloc_ptr. Thi fixes a latent bug in this function, where
the error path previously ran the cleanups and then referred to one of
the objects just freed.
2017-01-10 Tom Tromey <tom@tromey.com>
* python/python.c (python_run_simple_file): Use
unique_xmalloc_ptr, gdbpy_ref.
This changes some spots in py-prettyprint.c to use gdbpy_ref. It also
changes push_dummy_python_frame to be a class, rather than having it
create a cleanup.
2017-01-10 Tom Tromey <tom@tromey.com>
* python/py-prettyprint.c (print_stack_unless_memory_error)
(print_string_repr, print_children): Use gdbpy_ref.
(dummy_python_frame): New class.
(dummy_python_frame::dummy_python_frame): Rename from
push_dummy_python_frame.
(py_restore_tstate): Remove.
This changes py_print_frame to use gdbpy_ref in a few spots.
2017-01-10 Tom Tromey <tom@tromey.com>
* python/py-framefilter.c (py_print_frame): Use gdbpy_ref.
All of gdb has been converted away from ensure_python_env and
varobj_ensure_python_env now; so remove them.
2017-01-10 Tom Tromey <tom@tromey.com>
* python/python.c (ensure_python_env, restore_python_env):
Remove.
* python/python-internal.h (ensure_python_env): Don't declare.
* varobj.h (varobj_ensure_python_env): Don't declare.
* varobj.c (varobj_ensure_python_env): Remove.
This changes the last function in varobj.c to use gdbpy_enter_varobj.
2017-01-10 Tom Tromey <tom@tromey.com>
* varobj.c (varobj_value_get_print_value): Use
gdbpy_enter_varobj.
