The big lines are:
NODEV -> NULL
NOUDEV -> NODEV
udev_t -> dev_t
udev2dev() -> findcdev()
Various minor adjustments including handling of userland access to kernel
space struct cdev etc.

This is a corresponding change to bin/67994. I'll soon commit
bin/67994 into 4-STABLE. Actually, 5-CURRENT's getaddrinfo()
doesn't have the problem mentiond in bin/67994. However, it is
good to be in sync variable name with 4-STABLE and KAME.

* Restore directories with 0700 permissions initially,
then use the fixup pass to correct the permissions
* Trim trailing "/" and "/." in mkdirpath()

sigsuspend, thread shouldn't wait, in old code, it may be
ignored.
When a signal handler is invoked in sigsuspend, thread gets
two different signal masks, one is in thread structure,
sigprocmask() can retrieve it, another is in ucontext
which is a third parameter of signal handler, the former is
the result of sigsuspend mask ORed with sigaction's sa_mask
and current signal, the later is the mask in thread structure
before sigsuspend is called. After signal handler is called,
the mask in ucontext should be copied into thread structure,
and becomes CURRENT signal mask, then sigsuspend returns to
user code.

on all inputs of the form x.75, where x is an even integer and
log2(x) = 21. A similar problem occurred when rounding upward.
The bug involves the following snippet copied from rint():
i>>=1;
if((i0&i)!=0) i0 = (i0&(~i))|((0x100000)>>j0);
The constant 0x100000 should be 0x200000. Apparently this case was
never tested.
It turns out that the bit manipulation is completely superfluous
anyway, so remove it. (It tries to simulate 90% of the rounding
process that the FPU does anyway.) Also, the special case of +-0 is
handled twice (in different ways), so remove the second instance.
Throw in some related simplifications from bde:
- Work around a bug where gcc fails to clip to float precision by
declaring two float variables as volatile. Previously, we
tricked gcc into generating correct code by declaring some
float constants as doubles.
- Remove additional superfluous bit manipulation.
- Minor reorganization.
- Include <sys/types.h> explicitly.
Note that some of the equivalent lines in rint() also appear to be
unnecessary, but I'll defer to the numerical analysts who wrote it,
since I can't test all 2^64 cases.

permission), try to continue in FTS_DONTCHDIR mode. Of course this
won't work for long paths, but we can't descend more than one pathname
component beyond the directory anyway if we lack search permission.
Here is a transcript demonstrating the change, where oldls is ls(1)
linked with the old fts(3):
das@VARK:~> mkdir t && touch t/{a,b,c} && chmod u-x t
das@VARK:~> oldls t
a b c
das@VARK:~> oldls -l t
das@VARK:~> \ls t
a b c
das@VARK:~> \ls -l t
ls: a: Permission denied
ls: b: Permission denied
ls: c: Permission denied
I had forgotten about this patch until bde reminded me. He reports
using it without problems for over a year.

The issue of whether this is the right errno for funopened streams is
unresolved, but that's an obscure case, and some errno is better than
no errno.

distinguish files from dirs (trailing '/' indicated a dir). Since
POSIX.1-1987, this convention is no longer necessary. However, there
are current tar programs that pretend to write POSIX-compliant
archives, yet store directories as "regular files", relying on this
old filename convention to save them. <sigh> So, move the check for
this old convention so it applies to all tar archives, not just those
identified as "old."

it sees a truncated input the first time it gets called.
(In particular, files shorter than 512 bytes cannot be tar archives.)
This allows the top-level archive_read_next_header code to
generate a proper error message for unrecognized file types.
Pointed out by: numerous ports that expect tar to extract non-tar files ;-(

It does not appear to be possible to cross-build arm from i386 at the
moment, and I have no ARM hardware anyway. Thus, I'm sure there are
bugs. I will gladly fix these when the arm port is more mature.
