For the moment I've called it ``gdb_stdlog'' and added it to main.c  At
the same time I've updated (fixed I would argue :-) remote.c and
gdbarch.c so that they send their trace/log messages to gdb_stdlog and
not gdb_stdout.

By default gdb_stdlog ends up in gdb_stdout so the TUI and normal users
won't notice any difference.
