warning workaround.

Accept "set foo unlimited" in integer/uinteger/zuinteger_unlimited commands.

Currently, several commands take "0" or "-1" to mean "unlimited".

"show" knows when to print "unlimited":

 (gdb) show height
 Number of lines gdb thinks are in a page is 45.
 (gdb) set height 0
 (gdb) show height
 Number of lines gdb thinks are in a page is unlimited.

However, the user can't herself specify "unlimited" directly:

 (gdb) set height unlimited
 No symbol table is loaded.  Use the "file" command.
 (gdb)

This patch addresses that, by adjusting the set handler for all
integer/uinteger/zuinteger_unlimited commands to accept literal
"unlimited".  It also installs a completer.  Presently, we complete on
symbols by default, and at
<http://sourceware.org/ml/gdb-patches/2013-03/msg00864.html> I've
shown a WIP prototype that tried to keep that half working in these
commands.  In the end, it turned out to be more complicated than
justifiable, IMO.  It's super rare to want to pass the value of a
variable/symbol in the program to a GDB set/show knob.  That'll still
work, it's just that we won't assist with completion anymore.  This
patch just sticks with the simple, and completes on "unlimited", and
nothing else.  This simplification means that

  "set he<tab><tab>"

is all it takes to get to:

  "set height unlimited"

The patch then goes through all integer/uinteger/zuinteger_unlimited
commands in the tree, and updates both the online help and the manual
to mention that "unlimited" is accepted in addition to 0/-1.  In the
cases where the command had no online help text at all, this adds it.
I've tried to make the texts read in a way that "unlimited" is
suggested before "0" or "-1" is.

Tested on x86_64 Fedora 17.

make -gdb-exit call disconnect_tracing too, and don't lose history if the target errors on "quit"

Gareth mentions in PR gdb/15275:

 "The MI '-gdb-exit' command mi_cmd_gdb_exit() never calls disconnect_tracing()
 and therefore exits correctly."

It should, so to get out of tfind mode, as quit may detach instead of
kill, and we don't want to confuse the memory/register accesses
etc. of the detach process.  So we should push down the disconnect
tracing bits at least to quit_force.  But we can't as is, as that
would swallow the error thrown by answering "no" to:

  Trace is running but will stop on detach; detach anyway? (y or n)

So to address that, we split disconnect_tracing in two.  One part that
does the query, and another part that does the rest, and we make
quit_force call the latter.

Looking at quit_force, it does several things, some of which are a bit
independent of the others.  It first kills/detaches, and then writes
history, and then runs the final cleanups.  It seems better to me to
do each of these things even if the previous thing throws.  E.g., as
is, if something throws while detaching, then we skip writing history.

Tested on x86_64 Fedora 17.

*** empty log message ***

Increase the accuracy of sparc instruction aliases.

Make current with UA2011 specification.

Add an F_PREFERRED opcode flag that indicates a preferred alias
when multiple aliases for the same opcode exists.

For 'lzd':

Add 'lzcnt' as primary instruction, and make 'lzd' an alias.

Add 'ldtw', 'ldtwa', 'sttw', 'sttwa':

The modern opcode for for 'ldd', 'ldda', 'std', and 'stda' on
integer registers.  Mark the latter now as aliases.

For 'flush':

Support "[address]" syntax as well as plain "address".

Rework 'mov' aliases for 'wr':

Eliminate bogus three operand moves, and encode the
instructions properly for the "mov REG, %ASR" cases,
specifically we should encode the register in rs2 not rs1 as
per The SPARC V8 Architecture Manual.

Add missing cbcond aliases:

c{w,x}bz, c{w,x}blu, c{w,x}bnz, c{w,x}bgeu

Add 'd' suffix VIS logical ops:

The primary opcode for 'fzero' is now 'fzerod' (compare with
'fzeros'), for example.  And thus 'fzero' is now an alias.

Add modern opcodes for condition code setting edge instructions:

They are now edgeN{,l}cc instead of plain edgeN{,l}.

Add modern opcodes for VIS comparisons:

All VIS comparisons now start with prefix "fp", retain the
older variants as aliases.

The signed variants for equal and not-equal have "u" aliases
to show that these comparisons are equally suited for unsigned
compares.

Update existing test cases as needed, and add several new ones.

mark existing mnenomics as aliases.  Add "cc" suffix to edge
instructions generating condition codes, mark existing mnenomics
as aliases.  Add "fp" prefix to VIS compare instructions, mark
existing mnenomics as aliases.

For example:

A related issue is that the "commands" command actually supports
setting commands to a range of breakpoints/tracepoints at once.  But,
hacking "maint info breakpoints" to print t->step_count, reveals:

that tracepoint 6 doesn't end up with the correct step_count.

The issue is that here:

 static void
 do_map_commands_command (struct breakpoint *b, void *data)
 {
  struct commands_info *info = data;

  if (info->cmd == NULL)
    {
      struct command_line *l;

      if (info->control != NULL)
l = copy_command_lines (info->control->body_list[0]);
      else
{
  struct cleanup *old_chain;
  char *str;

  str = xstrprintf (_("Type commands for breakpoint(s) "
      "%s, one per line."),
    info->arg);

  old_chain = make_cleanup (xfree, str);

  l = read_command_lines (str,
  info->from_tty, 1,
  (is_tracepoint (b)
   ? check_tracepoint_command : 0),
  b);

  do_cleanups (old_chain);
}

      info->cmd = alloc_counted_command_line (l);
    }

validate_actionline is never called for tracepoints other than the
first (the copy_command_lines path).  Right below, we have:

  /* If a breakpoint was on the list more than once, we don't need to
     do anything.  */
  if (b->commands != info->cmd)
    {
      validate_commands_for_breakpoint (b, info->cmd->commands);
      incref_counted_command_line (info->cmd);
      decref_counted_command_line (&b->commands);
      b->commands = info->cmd;
      observer_notify_breakpoint_modified (b);
    }

And validate_commands_for_breakpoint looks like the right place to put
a call; if we reset step_count there too, we have a nice central fix
for the first issue as well, because trace_actions_command calls
breakpoint_set_commands that also calls
validate_commands_for_breakpoint.

We end up calling validate_actionline twice for the first tracepoint,
since read_command_lines calls it too, through
check_tracepoint_command, but that should be harmless.
