continue_to_breakpoint always continues to the next breakpoint, not to the
one named in parameter. This rendered the tests effectively useless, since
marker2 was never reached.

Assuming displaced stepping is enabled, and a breakpoint is set in the
memory region of the scratch pad, things break. One of two cases can
happen:
#1 - The breakpoint wasn't inserted yet (all threads were stopped), so
after setting up the displaced stepping scratch pad with the
adjusted copy of the instruction we're trying to single-step, we
insert the breakpoint, which corrupts the scratch pad, and the
inferior executes the wrong instruction. (Example below.)
This is clearly unacceptable.
#2 - The breakpoint was already inserted, so setting up the displaced
stepping scratch pad overwrites the breakpoint. This is OK in
the sense that we already assume that no thread is going to
executes the code in the scratch pad range (after initial
startup) anyway.
This commit addresses both cases by simply punting on displaced
stepping if we have a breakpoint in the scratch pad range.
The #1 case above explains a few regressions exposed by the AS/NS
series on x86:

Enabling "maint set target-non-stop on" implies displaced stepping
enabled as well, and it's the latter that's to blame here. We can see
the same failures with "maint set target-non-stop off + set displaced
on".

Note the breakpoint at main is set at 0x080481c1. Right at the

should write 0x4d to the address pointed at by $esp. However, if we
stepi, the program manages to write 52301/0xcc4d there instead (0xcc
is int3, the x86 breakpoint instruction), because the breakpoint
address is 4 bytes inside the scratch pad location, which is
0x080481bd:
(gdb) p 0x080481c1 - 0x080481bd
$1 = 4
IOW, instead of executing:
"c7 04 24 4d 00 00 00" [ movl $0x4d,(%esp) ]
the inferior executes:

Nowadays, test gdb.threads/wp-replication.exp uses a while loop to
repeatedly insert HW watchpoint, resume and check no error message
coming out, in order to count HW watchpoints There are some
drawbacks in this way,
- the loop could be endless. I think this is use to making trouble
to S/390, since we had such comment
# Some targets (like S/390) behave as though supporting
# unlimited hardware watchpoints. In this case we just take a
# safe exit out of the loop.
I hit this today too because a GDB internal error is triggered
on "continue" in the loop, and $done is 0 invariantly, so the loop
can't end.
- the code counting hardware watchpoint is too complicated. We can
use "set breakpoint always-inserted on" to get the result of inserting
HW watchpoint without resuming the inferior. In this way,
watch_count_done and empty_cycle in c file is no longer needed.
In this patch, I change to use "set breakpoint always-inserted on" trick,
and only iterate $NR_THREADS times, to count the HW watchpoint. In this
way, the loop can't be endless, and GDB doesn't need to resume the inferior.

getdents buffer size is given in bytes, not dirent entries (which have
variable size anyway). We don't need size_dirent and size_dirent64 for

a somewhat different structure. Accordingly, rename size_dirent
to size_old_dirent.

The values were mistakenly set to size of glibc's sigset_t (128 bytes)

This fixes this error in C++ mode:
/home/pedro/gdb/mygit/cxx-convertion/src/gdb/mdebugread.c:654:11: error: invalid conversion from ‘int’ to ‘address_class’ [-fpermissive]
theclass = mdebug_register_index;
^
The "theclass" local is of type enum address_class, however, what it
really holds is an address class index. Class index values by design
match the address class values up until LOC_FINAL_VALUE, but extend
beyond that, so it's not really right to store an address class index
in an enum address_class.
The fix is really the same making the 'theclass' local be of type int,
but while we're at it, we get rid of the goto, and thus the local
becomes the 'aclass_index' parameter in the new add_data_symbol
function.

I actually carried a different fix in the C++ branch that removed this
assignment and then adjusted all callers that depended on it. The
thinking was that this is for the case where we're returning false,
indicating end of iteration. But that results in a much larger and
tricker patch; looking back it seems quite pointless. I looked at the
history of GCC's C++ conversion and saw that they added this same cast
to their version of vec.h, FWIW. (GCC's vec.h is completely different
nowadays, having been converted to templates meanwhile.)

I looked at changing these is_destructor_name/is_constructor_name
interfaces in order to detangle the boolean result from the ctor/dtor

to the libiberty demangler interfaces. E.g, include/demangle.h:
~~~
/* Return non-zero iff NAME is the mangled form of a constructor name
in the G++ V3 ABI demangling style. Specifically, return an `enum
gnu_v3_ctor_kinds' value indicating what kind of constructor
it is. */
extern enum gnu_v3_ctor_kinds
is_gnu_v3_mangled_ctor (const char *name);
enum gnu_v3_dtor_kinds {
gnu_v3_deleting_dtor = 1,
gnu_v3_complete_object_dtor,
gnu_v3_base_object_dtor,
/* These are not part of the V3 ABI. Unified destructors are generated
as a speed-for-space optimization when the -fdeclone-ctor-dtor option
is used, and are always internal symbols. */
gnu_v3_unified_dtor,
gnu_v3_object_dtor_group
};
~~~
libiberty/cp-demangle.c:

This is code parsing RSP signal numbers, checking whether the numbers
are indeed valid/known GDB signals, and then converting to host signal
numbers. I considered adding temporary enum gdb_signal variables
instead, but didn't really like the result.

* server.c (handle_v_cont, process_serial_event): Add enum
gdb_signal casts to signal parsing code.
