Make outs() close its file when its stream is destructed, so that
pending output errors are detected.

llvm-svn: 111643

Delete raw_stdout_ostream and raw_stderr_ostream, which are unused
outside of outs() and errs() themselves, and they don't really
need custom classes.

llvm-svn: 111642

Move raw_ostream's Error flag into raw_fd_ostream, as that's the only
class which is using it.

Make raw_fd_ostream consider itself the owner of STDOUT_FILENO when
constructed with an output filename of "-". In particular, allow the
file descriptor to be closed, and close the file descriptor in the
destructor if it hasn't been explicitly closed already, to ensure
that any write errors are detected.

Fix the rest of rdar://8318441 which happens when a raw_fd_ostream
(e.g. errs()) fails in close() due to (e.g.) a broken pipe. As
previously written, the had_error() flag would get set and then
the raw_ostream dtor would report a fatal error. There is nothing
the client can do about this and we have no way to report the error,
so just eat it.

Usage of O_NONBLOCK in bjam is now confirmed as a bug and fixed upstream.
Update the comment.

Handle the case where open(2) or close(2) is interrupted by a signal when
automatic syscall restarting is disabled.

Also, fix the build on systems which don't define EWOULDBLOCK.

llvm-svn: 103158

Handle EWOULDBLOCK as EAGAIN. And add a comment explaining why
EAGAIN and EWOULDBLOCK are used here.

Also, handle the case where a write call is interrupted after
some data has already been written.
