lowest level of these routines and capture all output from the rest of GDB.

Under some circumstances, you may want to collect the output so that it can
be returned as the value of a tcl procedure. This can be done by
surrounding the output routines with calls to start_saving_output and
finish_saving_output. The saved data can then be retrieved with
get_saved_output (but this must be done before the call to
finish_saving_output). */

This fixes odd TCL errors when hitting stop button. * (tk_command): Don't pass interp->result on to Tcl_{Var}Eval, as that will trash the result. strdup the result instead and pass that on. Improve error handling as well. * gdbtk.tcl (gdbtk_tcl_flush): Use global def of current_output_win. Makes flushing actually work! * (asm_win_name create_asm_win update_assembly): Bunch of fixes to make assembly windows stop flashing when loading a new file. * (gdbtk_tcl_busy gdbtk_tcl_idle): Use catch to prevent gdb_cmd errors from losing control. * (create_source_window): Add source file selection to View menu. * (create_command_window (<Key-Return> binding): Quote text fed into gdb_cmd to prevent eval errors.

* gdbtk.c (gdbtk_wait gdbtk_init): Use different method of enabling I/O interrupts for SVR4 (streams). * (start_saving_output save_output get_saved_output finish_saving_output flush_holdbuf gdbtk_flush gdbtk_fputs gdbtk_init): Totally revamp to use TCLs dynamic string functions. Also, quote all data passed back to TCL to prevent errors with unmatched braces, odd characters, etc... This fixes several wierd problems with outputting strings containing unmatched braces. * (breakpoint_notify gdb_loc): Use long hex format to output addresses of breakpoints and PCs. This fixes some Alpha problems. * (breakpoint_notify): Add stream arg to call to gdbtk_fputs. * (gdb_listfiles): Also, go through the symtabs when looking for files. This makes xcoff work (sort of), but probably breaks something else. * (gdb_stop): Return TCL_OK instead of nothing. This fixes odd TCL errors when hitting stop button. * (tk_command): Don't pass interp->result on to Tcl_{Var}Eval, as that will trash the result. strdup the result instead and pass that on.
