[PATCH 0/1] pseudo: honor umask again

[Peter Seebach <peter.seebach@windriver.com>]

The fchmodat patch subtly broke umask support. The key here is that
since I was thinking about chmod, chmod is what I tested, and chmod
ignores umask. But the patch had the side effect of masking in 022
bits if they were set in the requested mode for an open/mkdir/mknod,
even if umask would have removed them from the filesystem.

This patch corrects that, and also in passing removes a completely
spurious double-mask-out of extra bits. It turns out that
	((x) & ~y)
is just as good as
	(((x) & ~y) & ~y)

The patch looks larger than it really is, just because diffs-of-diffs;
the substance is that each of the mknod/mkdir/open functions which
actually works with the mode flag now masks out pseudo_umask, which
is set during the initial pseudo client setup, and updated whenever
umask is called.

Many thanks to kroon in #yocto for bringing this to my attention.
