[RFC PATCH v2 0/7] O_IGNORE_CTTY everywhere & misc fixes

[Sergey Bugaev]

Changes since v1:
* Addressed nits
* Made improvements to daemon () as discussed
* Fixed std{in,out,err} mode in csu/check_fds.c
* Tweaked the comment on O_IGNORE_CTTY

But also, I found out that opening some internal files (specifically
I have noticed this about nsswitch.conf) still triggers the
term_getctty () RPC -- and that's because they're opened with
fopen (), not plain open (). Is there anything we can do abiut this?

I suppose there's no way we're could introduce a new fopen () mode
character just for this?

Even with the fopen-using callsites left out, not making ctty RPCs in
all the other cases is still a solid improvement.
