* makeint.h: Change OUT_OF_MEM() macro to out_of_memory() function.
* output.h, job.h: Move FD_* macros from job.h to output.h.
* output.c (output_write): Write a buffer to an FD directly.
(out_of_memory): Use output_write() to avoid allocating more
memory while writing the error, and call exit() instead of die().
This does mean we can't translate the error string, though.
* misc.c (xmalloc, xcalloc, xrealloc, xstrdup, xstrndup): Call new
out_of_memory() rather than OUT_OF_MEM().
* read.c (parse_file_seq): Ditto.
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.
Create a new file, output.c, and collect functions that generate output there.
We introduce a new global context specifying where output should go (to stdout
or to a sync file), and the lowest level output generator chooses where to
write output based on that context.
This allows us to set the context globally, and all operations that write
output (including functions like $(info ...) etc.) will use it.
Removed the "--trace=dir" capability. It was too confusing. If you have
directory tracking enabled then output sync will print the enter/leave message
for each synchronized block. If you don't want that, disable directory
tracking.
