* defs.h, infrun.c (wait_for_inferior), top.c: Call
target_wait_hook to allow GUI to handle blocking for inferior. Call call_command_hook in execute_command to provide means for wrapping commands with GUI state change updates. * gdbtk.c (gdb_cmd): Force GUI into idle mode when errors occur. * (gdb_stop): New tcl command to stop the target process. * (x_event, gdbtk_wait): Allow GUI to interrupt gdb out of target waits. * (gdbtk_call_command): Wrapper around command processing to alert GUI of target state changes. * (gdbtk_init): Get the fd of X server for doing async notification of X events (via x_event). Setup new hooks. * gdbtk.tcl: Add scrollbars to assembly and command windows. * Change window foreground & background colors. * Create margin tag for breakpoints in source and assembly windows. * Add new routines to be invoked when target state changes to/from idle. * Add start of expression window. * Change bindings of mouse button 1 in assembly and source window to just set or clear breakpoints when in the margin tag. * Change shape of register window to be more vertical to better reflect it's contents. * Add stop button. * Cleanup some code around command window bindings. * infrun.c (wait_for_inferior): Make sure through_sigtramp_breakpoint is non-null before deleting.
