523d4f80c3 Implement stopped_by_sw_breakpoint for Windows gdbserver 
This changes the Windows gdbserver port to implement the
stopped_by_sw_breakpoint target method.  This is needed to support
pending stops.

This is a separate patch now, because Pedro suggested splitting it out
for simpler bisecting, in the case that it introduces a bug.

2c1d95e869 Move wait_for_debug_event to nat/windows-nat.c 
This moves the wait_for_debug_event helper function to
nat/windows-nat.c, and changes gdbserver to use it.
wait_for_debug_event is a wrapper for WaitForDebugEvent that also sets
last_wait_event when appropriate.  This is needed to properly handle
queued stops.

e758e19c59 Share some inferior-related Windows code 
This adds a couple of functions to nat/windows-nat.c and changes gdb
and gdbserver to use them.  One function checks the list of pending
stops for a match (not yet used by gdbserver, but will be in a
subsequent patch); and the other is a wrapper for ContinueDebugEvent
that always uses the last "real" stop event.

Both gdb and gdbserver have a "handle_exception" function, the bulk of

a816ba1897 Share handle_load_dll and handle_unload_dll declarations 
This changes nat/windows-nat.h to declare handle_load_dll and
handle_unload_dll.  The embedding application is required to implement
these -- while the actual code was difficult to share due to some
other differences between the two programs, sharing the declaration
lets a subsequent patch share more code that uses these as callbacks.

This changes gdb and gdbserver to use the same calling convention for
