    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.

commit 4210d83ee607bffaf27a235f0475bf1e5ea8266d

    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.
