Support the -Orecurse option properly.

Browse Source 
In this mode we still collect all the output from a given target and
dump it at once.  However we don't treat recursive lines any differently
from non-recursive lines.  Also we don't print enter/leave messages
after every dump.  However we do ensure that we always print them once
to stdout, so the parent make will collect it properly.

2013-09-14 Paul Smith <psmith@gnu.org>
* misc.c (set_append_mode, open_tmpfd, open_tmpfile): Move to output.c.
* misc.h: Ditto.
* output.h: Ditto.
* main.c (main): Move stdio init into output.c:output_init().
Change open_tmpfile() to output_tmpfile().
* output.c: Rename open_*() to output_*(). set_append_mode() and
open_tmpfd() are static.
(_outputs, log_working_directory): Accept a struct output and
print to that rather than the global context.
(output_dump): In recurse mode print enter/leave once for the
whole makefile.
(output_init): Initialize this processes stdio as well as child's.
* vmsjobs.c: Reformat to be closer to convention.
