Re: [RFA] implement putchar_filtered()

[Fernando Nasser <fnasser at cygnus dot com>]

We should not be using the functions that default to gdb_stdout anymore.
This makes it impossible to have gdb as a library, to have script
languages front ends etc.

The fputc_filtered() is useful during the transition as it has the
stream as a parameter that can be set to a memory file and retrieved
by the caller.
