Small style violation fix in ada_array_bound_from_type

wrong dimension found in ada-lang.c:ada_array_bound_from_type

This function has the following code:

  elt_type = type;
  for (i = n; i > 1; i--)
    elt_type = TYPE_TARGET_TYPE (type);

For multi-dimension arrays, the code above tries to find the array
type corresponding to the dimension we're trying to inspect.
The problem is that, past the second dimension, the loop does
nothing other than repeat the first iteration. There is a little
thinko where it got the TYPE_TARGET_TYPE of TYPE instead of ELT_TYPE!

To my surprise, I was unable to produce an Ada exemple that demonstrated
the problem.  That's because the examples I created all trigger a parallel
___XA type which we then use in place of the ELT_TYPE in order to
determine the bounds - see the code that immediately follows our
loop above:

    index_type_desc = ada_find_parallel_type (type, "___XA");
    ada_fixup_array_indexes_type (index_type_desc);
    if (index_type_desc != NULL)
    [...]

So, in order to avoid depending on an Ada example where the compiler
can potentially decide one way or the other, I decided to use an
artificial example, written in C. With ...

  int multi[1][2][3];

... forcing the language to Ada, and trying to print the 'last,
we get:

    (gdb) p multi'last(1)
    $1 = 0
    (gdb) p multi'last(2)
    $2 = 1
    (gdb) p multi'last(3)
    $3 = 1   <<<---  This should be 2!

Additionally, I noticed that a couple of check_typedef's were missing.
This patch adds them. And since the variable in question only gets
used within an "else" block, I moved the variable declaration and
use inside that block - making it clear what the scope of the variable
is.

gdb/ChangeLog:

        * ada-lang.c (ada_array_bound_from_type): Move the declaration
        and assignment of variable "elt_type" inside the else block
        where it is used.  Add two missing check_typedef calls.
        Fix bug where we got TYPE's TYPE_TARGET_TYPE, where in fact
        we really wanted to get ELT_TYPE's TYPE_TARGET_TYPE.

        * gdb.ada/arraydim: New testcase.

Do the target-waiting within do_initial_child_stuff on Windows.

This is a preparatory patch that achieves two goals:

  . Makes the initial event handling more similar to GDB's;
  . Opens the door for implementing post-inititial-handling
    operations.

At the moment, this is only done on Windows, where the
post-initial-handling is going to be needed (in the context of
Windows 2012). And because we're close to creating the gdb 7.7
branch, making that change for all platforms is a little more
risk that we'd like. So the change is currently implemented
on Windows.

gdb/gdbserver/ChangeLog:

        * target.c (mywait): Set OURSTATUS->KIND to TARGET_WAITKIND_STOPPED
        if equal to TARGET_WAITKIND_LOADED.
        * win32-low.c (cached_status): New static global.
        (win32_wait): Add declaration.
        (do_initial_child_stuff): Flush all initial pending debug events
        up to the initial breakpoint.
        (win32_wait): If CACHED_STATUS was set, return that instead
        of doing a real wait.  Remove the code resuming the execution
        of the inferior after receiving a TARGET_WAITKIND_LOADED event
        during the initial phase.  Also remove the code changing
        OURSTATUS->KIND from TARGET_WAITKIND_LOADED to
        TARGET_WAITKIND_STOPPED.
nameless LOAD_DLL_DEBUG_EVENT causes ntdll.dll to be missing

This is the gdbserver-equivalent of the change made in GDB to handle
the case, in x64 windows version 2012, where the kernel produces
a LOAD_DLL_DEBUG_EVENT where the name of the associated DLL cannot
be determined at that time, and thus has to be processed later.

The visible symptom is that ntdll.dll is missing from the list of
shared libraries known to be mapped by the inferior, with other
side-effects such as failure to unwind through code provided by
that DLL (such as exception handling routines).

gdb/gdbserver/ChangeLog:

	* Makefile.in (safe-ctype.o, lbasename.o): New rules.
	* configure.srv: Add safe-ctype.o and lbasename.o to srv_tgtobj
	for all targets that use win32-low.c.
	* win32-low.c (win32_ensure_ntdll_loaded): New function.
	(do_initial_child_stuff): Add call to win32_ensure_ntdll_loaded.
