The commit 'ash: eval: Return status in eval functions' changed how
exit status is handled in eval functions. The case of nofork
applets was missed, resulting in the incorrect status potentially
being returned for nofork applets when FEATURE_SH_NOFORK is enabled.

Here, not handling the error is would just eat one input 0xff char.
Correct handling would need even more corner case handling,
as-is buggy handling corrupts the buffer.
Since we just been told by kernel that pty is ready,
EAGAIN should not be happening here anyway.

If a write to pty is short, remove_iacs() can be run on a buffer repeatedly.
This, for example, can eat 0xff chars (IACs, in telnet terms).
Rework the logic to handle IACs in a special "write to pty" function.

By user's request.
Decided to not use fcntl(F_SETLKW) in lieu of problems with locking
on networked filesystems. The existence of /var/run/ifstate.new
is treated as a write lock. rename() provides atomicity.

Previous commit probably introduced a bug:
non-matching size calculation in size counting and
actual copying caused by SHELL_ALIGN being applied differently!
This won't bite if string sizes are also SHELL_ALIGNed.
Thus fixing.

Added NOINLINE to two function, since my version of gcc would actualy increase
code size otherwise.

As usual, by multiplying directories - "dhcpd_eth0", "dhcpd_wlan1"

dash has tokendlist[] array to decide which tokens end lists.
We store it as first byte of each tokname_array[i].
Switch to bit array, name it like dash (tokendlist), drop special
1st byte of tokname_array[i]. This brings us closer to dash, and
shrinks the binary, because many more string aliasing opportunities
are now open:
