I happen to see traceframe_fun and traceframe_sal are static variables,
which are not necessary to me. They are only used in set_traceframe_context,
and they are not stateful. This patch is to remove them.

startup-with-shell" option.
Occasionaly we hear about people having problems with GDB not being
able to start programs (with "run"/"start"). GDB spawns a shell to
start the program, and most often, it'll be the case that the problem
is actually with the user's shell setup.
GDB has code to disable the use of the shell to start programs.
That's the STARTUP_WITH_SHELL macro that native targets could set to 0
in their nm.h file (though no target actually uses it nowadays).
This patch makes that setting a run-time knob instead. This will be
useful to quickly diagnose such shell issues, and might also come in
handy at other times (such as when debugging the shell itself, if you
don't have a different shell handy).

signal names.
The other day while debugging something related to random signals, I
got confused with "set debug infrun 1" output, for it said:
infrun: TARGET_WAITKIND_STOPPED
infrun: stop_pc = 0x323d4e8b94
infrun: random signal 20
On GNU/Linux, 20 is SIGTSTP. For some reason, it took me a few
minutes to realize that 20 is actually a GDB signal number, not a
target signal number (duh!). In any case, I propose making GDB's
output clearer here:
One way would be to use gdb_signal_to_name, like already used
elsewhere:
infrun: TARGET_WAITKIND_STOPPED
infrun: stop_pc = 0x323d4e8b94
infrun: random signal SIGCHLD (20)
but I think that might confuse someone too ("20? Why does GDB believe
SIGCHLD is 20?"). So I thought of printing the enum string instead:
infrun: TARGET_WAITKIND_STOPPED
infrun: stop_pc = 0x323d4e8b94
infrun: random signal GDB_SIGNAL_CHLD (20)
Looking at a more complete infrun debug log, we had actually printed
the (POSIX) signal name name a bit before:
infrun: target_wait (-1, status) =
infrun: 9300 [Thread 0x7ffff7fcb740 (LWP 9300)],
infrun: status->kind = stopped, signal = SIGCHLD
...
infrun: TARGET_WAITKIND_STOPPED
infrun: stop_pc = 0x323d4e8b94
infrun: random signal 20
So I'm now thinking that it'd be even better to make infrun output
consistently use the enum symbol string, like so:
infrun: clear_proceed_status_thread (Thread 0x7ffff7fca700 (LWP 25663))
infrun: clear_proceed_status_thread (Thread 0x7ffff7fcb740 (LWP 25659))

infrun: target_wait (-1, status) =
infrun: 25659 [Thread 0x7ffff7fcb740 (LWP 25659)],
- infrun: status->kind = stopped, signal = SIGCHLD
+ infrun: status->kind = stopped, signal = GDB_SIGNAL_CHLD
infrun: infwait_normal_state
infrun: TARGET_WAITKIND_STOPPED
infrun: stop_pc = 0x400700
- infrun: random signal 20
+ infrun: random signal (GDB_SIGNAL_CHLD)
infrun: random signal, keep going
- infrun: resume (step=1, signal=20), trap_expected=0, current thread [Thread 0x7ffff7fcb740 (LWP 25659)] at 0x400700
+ infrun: resume (step=1, signal=GDB_SIGNAL_CHLD), trap_expected=0, current thread [Thread 0x7ffff7fcb740 (LWP 25659)] at 0x400700
infrun: prepare_to_wait
infrun: target_wait (-1, status) =
infrun: 25659 [Thread 0x7ffff7fcb740 (LWP 25659)],
- infrun: status->kind = stopped, signal = SIGTRAP
+ infrun: status->kind = stopped, signal = GDB_SIGNAL_TRAP
infrun: infwait_normal_state
infrun: TARGET_WAITKIND_STOPPED
infrun: stop_pc = 0x400704
infrun: stepi/nexti
infrun: stop_stepping
GDB's signal numbers are public and hardcoded (see
include/gdb/signals.h), so there's really no need to clutter the
output with numeric values in some places while others not. Replacing
the magic "144" with GDB_SIGNAL_DEFAULT in "proceed"'s debug output
(see above) I think is quite nice.
I posit that all this makes it clearer to newcomers that GDB has its
own signal numbering (and that there must be some mapping going on).

In the first hunk, the format string was off-by-one for cmd, and cmd
itself was larger than the maximum size required. cmd was reduced in
size and the format string adjusted.
In the second hunk, the format string was off-by-one for local_address,
remote_address and extra, although the buffers for the two addresses
were large enough for this not to matter. The specifiers for the two
addresses was corrected, and a number of unused variables including
extra were suppressed from parsing.
In the third hunk, the format string was off-by-one for name,
dependencies and status. This code was rewritten using strtok since
dependencies can be arbitrarily long.

'*ecs' is always memset by handle_inferior_event's callers, so all
these clears are unnecessary. There's one place that sets the flag to
true, but, afterwards, before ecs->random_signal is ever read, we
reach the part of handle_inferior_even that clears ecs->random_signal,
among other things:
clear_stop_func (ecs);
ecs->event_thread->stepping_over_breakpoint = 0;
bpstat_clear (&ecs->event_thread->control.stop_bpstat);
ecs->event_thread->control.stop_step = 0;
stop_print_frame = 1;
ecs->random_signal = 0;
stopped_by_random_signal = 0;
So all these ecs->random_signal accesses are dead code.

This function still has comments referring back to when it was a goto
label in wait_for_inferior, eons ago. Looking closer, actually most
of its comments could use a facelift (contents/formatting/typos).

I realized that remote.c is not validating input here. Currently, if
a remote stub sends in an invalid signal number (or put another way,
if a future stub sends a new signal an old GDB doesn't know about),
GDB will do out of bounds accesses in the
signal_pass/signal_stop/signal_program arrays. It'll probably be a
long while before we add another signal number (and buggy stubs should
just be fixed), but can't hurt to be defensive.

- The Mach exception/signals escaped the TARGET_ -> GDB_ prefix change
done a while ago, but there's no real reason for that. I grepped
for TARGET_EXC and fixed all found, which unsurprisingly, means
darwin-nat.c needed fixing. I think the change there is as obvious
and trivial as it can get, so I'd be quite surprised if this broke
anything there somehow.
- GDB_SIGNAL_LAST's description string was unnecessarily inconsistent
with the enum name.

infrun: stop_pc = 0x323d4ba7c4
infrun: random signal 20
infrun: stepi/nexti
infrun: stop_stepping
So the inferior got a SIGCHLD (because the fork child exited while
we're doing 'si'), and since that signal is set to "nostop noprint
pass" (by default), it's considered a random signal, so it should not
cause a stop. But, it resulted in an immediate a stop_stepping call
anyway. So the single-step never really finished.
This is a regression caused by:

This patch fixes PR gdb/15995.
The bug here is that gdb's printf command does not flush the output
stream. This makes a printf that is not newline-terminated interleave
incorrectly with other forms of output, such as that generated via a
call to an external program using "shell".
I note that the "output" command already does this flushing.
The fix is to call gdb_flush in printf_command.

The first one, dw2_get_real_path from gdb/dwarf2read.c, was actually
making use of OBSTACK_CALLOC which already calls "sizeof" for its third
argument.
The second, download_tracepoint_1 from gdb/gdbserver/tracepoint.c, was
explicitly calling "sizeof" inside another "sizeof".
This patch fixed both functions.

both from gdb/target.c, do a "return" calling another function. But both
are marked as void. Despite the fact that the functions being called are
void as well, this is wrong. This patch fixes this by calling the functions
and then returning in the next line.
