* Remove unused parameters from SendDebugMessage functions * Add SendDebugEntry and SendDebugExit functions for tracking function entry/exit * Add indenting and function names to log entries * Remove unused debug functions * Eliminate now-unused hwnd parameter in initialization functions * Replace Log,LogEntry,LogExit functions with SendDebug equivalents in kmtip Many functions now have SendDebugEntry/SendDebugExit (or return_SendDebugExit) pairs. It is important to SendDebugExit on all returns from a function to keep the log indent depth consistent. In some cases I chose not to add these logging calls, e.g. on frequently called functions such as the message hooks.
