Change all references to stdout/stderr to gdb_stdout/gdb_stderr. Replace all calls to stdio output functions with calls to corresponding _unfiltered functions (`fprintf_unfiltered') Replaced calls to fopen for output to gdb_fopen. Added sufficient goo to utils.c and defs.h to make the above work. The net effect is that stdio output functions are only directly used in utils.c. Elsewhere, the _unfiltered and _filtered functions and GDB_FILE type are used. In the near future, GDB_FILE will stop being equivalant to FILE. The semantics of some commands has changed in a very subtle way: called in the right context, they may cause new occurences of prompt_for_continue() behavior. The testsuite doesn't notice anything like this, though. Please respect this change by not reintroducing stdio output dependencies in the main body of gdb code. All output from commands should go to a GDB_FILE. Target-specific code can still use stdio directly to communicate with targets.
