sync: add O_NOCTTY
fsync: drop O_NOATIME, add O_NONBLOCK, set exitcode to 1 if fsync() fails,
update --help message to be similar to sync.

in particular, they use same open() flags now

in oneline mode and if the address family is not AF_PACKET.

On platforms that don't support SIGWINCH vi can be configured
with FEATURE_VI_USE_SIGNALS disabled and FEATURE_VI_WIN_RESIZE
enabled. This allows the user to force an update with ^L when
the screen is resized.
However, because the SIGWINCH handler hasn't run the virtual
screen buffer won't have been updated and the display becomes
corrupted. Fix this by calling new_screen() if necessary.

If the MANPATH environment variable isn't set a provisional default
path of /usr/man is placed in man_path_list. This is only used if a
configuration file doesn't contain an alternative path.
If a configuration file lists the default path first:
MANPATH /usr/man:/usr/share/man
add_MANPATH() sees that the default entry is already present and skips
it. As a result man_path_list only contains the second and subsequent
components of the configured MANPATH.
In such cases the path should not be skipped.

Currently, running "udhcpc -n -b" causes udhcpc to go to background and
then exit after some time unless a lease is obtained.
It's not very useful to do so
as the calling process doesn't know
if the lease was obtained or not anyway.
The code actually tries to favor "-b" over "-n",
but doesn't clear "-n" flag while clearing "-b" after backgrounding.
So, clear "-n" flag after going into background.
This effectively makes "-b" override "-n" completely
and "-n -b" behave the same as "-b".
This allows to override default "-n" option, passed to udhcpc by ifupdown,
without recompiling busybox.

The following constructs result in ever-increasing memory usage:
while true; do { true; } </dev/null; done
while true; do ( true; ) </dev/null; done
For comparison, bash displays static memory usage in both cases.
This has been fixed in dash by commit 2bc6caa. The maintainer
writes:
I have simplified evaltree so that it simply sets the stack mark
unconditionally. This allows us to remove the stack marks in the
functions called by evaltree.
Closes BusyBox bug 7748.
