Fix off-by-one errors in *scanf format strings.
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.

Remove dead sets/clears of ecs->random signal.
'*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.

remote: Map invalid signal numbers to GDB_SIGNAL_UNKNOWN.
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.

Fix up a couple oddities in GDB's signal names and strings.
- 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.

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.

we'll now also fall through to all the "stepping" tests. For line
stepping, that'll turn out okay, as we'll just end up realizing the
thread is still in the stepping range, and needs to be re-stepped.
However, for stepi/nexti, we'll reach:

is to restore the keep_going call, but put it after the "switch back

There were two functions who were calling "sizeof" twice.
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.

This is a simple bug. target_disable_btrace and target_teardown_btrace,
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.

Document the -catch-assert and -catch-exception new GDB/MI commands.
This patch adds documentation for the new GDB/MI commands "-catch-assert"
and "-catch-exception", meant to provide the same functionality as
the "catch assert", "catch exception" and "catch exception unhandled"
CLI commands.
In the GDB Manual, there was already a section for catchpoint comments,
so that seemed like a natural place to document the new commands. But
commands related to a given concept seem to have traditionally been
organized alphabetically, and I didn't want future commands to break
down logical pairing of various commands. For instance, "-catch-load"
and "-catch-unload" are quite "distant" from each other, and it is easy
to imagine a new comment which would alphabetically fall in between,
causing them to be separated. So I introduced subsections to prevent
that from happening.

* NEWS: Add entry documenting the new "-catch-assert" and
"-catch-exception" GDB/MI commands.

* gdb.texinfo (Shared Library GDB/MI Catchpoint Commands):

Rework a bit Ada exception catchpoint support (in prep for GDB/MI)
This patch reworks a bit how the different steps required to insert
an Ada exception catchpoints are organized. They used to be:
1. Call a "decode" function which does:
1.a. Parse the command and its arguments
1.b. Create a SAL & OPS from some of those arguments
2. Call create_ada_exception_catchpoint using SAL as well
as some of the arguments extracted above.
The bulk of the change consists in integrating step (1.b) into
step (2) in order to turn create_ada_exception_catchpoint into
a function whose arguments are all user-level concepts. This
paves the way from a straightforward implementation of the equivalent
commands in the GDB/MI interpreter.
gdb/ChangeLog:
* ada-lang.c (ada_decode_exception_location): Delete.
(create_ada_exception_catchpoint): Remove arguments "sal",
"addr_string" and "ops". Add argument "ex_kind" instead.
Adjust implementation accordingly, calling ada_exception_sal
to get the entities it no longer gets passed as arguments.
Document the function's arguments.
(catch_ada_exception_command): Use catch_ada_exception_command_split
instead of ada_decode_exception_location, and update call to
create_ada_exception_catchpoint.
(catch_ada_assert_command_split): Renames
ada_decode_assert_location. Remove parameters "addr_string" and
"ops", and now returns void. Adjust implementation accordingly.
Update the function documentation.

warn if "source" fails to open the file when from_tty == 0
Consider the following example:
% gdb -q -batch -ex 'source nonexistant-file'
[nothing]
One would have at least expected the debugger to warn about
not finding the file, similar to the error shown when using
a more interactive mode. Eg:
(gdb) source nonexistant-file
nonexistant-file: No such file or directory.
Not raising an error appears to be intentional, presumably in order
to prevent this situation from stoping the execution of a GDB script.
But the lack of at least a warning makes it harder for a user to
diagnose any issue, if the file was expected to be there and readable.
This patch adds a warning in that case:
% gdb -q -batch -ex 'source nonexistant-file'
warning: nonexistant-file: No such file or directory.
