8ea0d8cff1 Add AS lookup functionality. On each hop we query a whois server to
find the corresponding AS for that IP (-a switch).
We can also choose a different whois server with the -A switch. The
default is whois.radb.net.

6f540420dd Two no-op fixes to improve corretness of syslogd code:
1) Use [AP]F_LOCAL rather than [AP]F_UNIX.
2) When copying a pipe's name, use f->f_un.f_pipe.f_pname, not f->f_un.f_fname.

1332875338 Add a geom class to map Linux LVM logical volumes.
The logical disks will appear as /dev/lvm/<vol group>-<logical vol>, for
instance /dev/lvm/vg0-home. G_LINUX_LVM currently supports linear stripes with
segments on multiple physical disks. The metadata is read only, logical
volumes can not be allocated or resized.

9e9d3bc9f1 Optimize for 3pi/4 <= |x| <= 9pi/4 in much the same way as for
pi/4 <= |x| <= 3pi/4.  Use the same branch ladder as for float precision.
Remove the optimization for |x| near pi/2 and don't do it near the
multiples of pi/2 in the newly optimized range, since it requires
fairly large code to handle only relativley few cases.  Ifdef out
optimization for |x| <= pi/4 since this case can't occur because it
is done in callers.

On amd64 (A64), for cos() and sin() with uniformly distributed args,
no cache misses, some parallelism in the caller, and good but not great
CC and CFLAGS, etc., this saves about 40 cycles or 38% in the newly
optimized range, or about 27% on average across the range |x| <= 2pi
(~65 cycles for most args, while the A64 hardware fcos and fsin take
~75 cycles for half the args and 125 cycles for the other half).  The
speedup for tan() is much smaller, especially relatively.  The speedup
on i386 (A64) is slightly smaller, especially relatively.  i386 is
still much slower than amd64 here (unlike in the float case where it
is slightly faster).

9ce8756044 Rearrange the polynomial evaluation for better parallelism. This
saves an average of about 8 cycles or 5% on A64 (amd64 and i386 --
more in cycles but about the same percentage on i386, and more with
old versions of gcc) with good CFLAGS and some parallelism in the
caller.  As usual, it takes a couple more multiplications so it will
be slower on old machines.

Convert to __FBSDID().

54c845efb9 Someday I might forgive the standards bodies for omitting timegm().
Maybe.  In the meantime, my workarounds for trying to coax UTC without
timegm() are getting uglier and uglier.  Apparently, some systems
don't support setenv()/unsetenv(), so you can't set the TZ env var and
hope thereby to coax mktime() into generating UTC.  Without that, I
don't see a really good alternative to just giving up and converting to
localtime with mktime().  (I suppose I should research the Perl library
approach for computing an inverse function to gmtime(); that might
actually be simpler than this growing list of hacks.)

75018fc592 Portability improvements:
* If the platform can't restore char nodes, block nodes, or fifos,
don't try and just return error.
  * Include O_BINARY in most open() calls (define O_BINARY to 0 if the
platform doesn't provide a definition already)
  * Refactor the ownership restore to more cleanly support platforms
that don't have any form of {l,f,}chown() call.
  * Comment a lingering issue with older Unix-like systems that allow
root to hose the filesystem.  I don't (yet) have a good solution for
this, but I expect it will require adding more redundant stat()
calls. <sigh>

This is a 'POLA' issue. This is a low risk change and should be MFC'd

38662c9698 Inline __ieee754__rem_pio2(). With gcc4-2, this gives an average
optimization of about 10% for cos(x), sin(x) and tan(x) on
|x| < 2**19*pi/2.  We didn't do this before because __ieee754__rem_pio2()
is too large and complicated for gcc-3.3 to inline very well.  We don't
do this for float precision because it interferes with optimization
of the usual (?) case (|x| < 9pi/4) which is manually inlined for float
precision only.

This has some rough edges:
- some static data is duplicated unnecessarily.  There isn't much after
  the recent move of large tables to k_rem_pio2.c, and some static data
  is duplicated to good affect (all the data static const, so that the
  compiler can evaluate expressions like 2*pio2 at compile time and
  generate even more static data for the constant for this).
- extern inline is used (for the same reason as in previous inlining of
  k_cosf.c etc.), but C99 apparently doesn't allow extern inline
  functions with static data, and gcc will eventually warn about this.

Convert to __FBSDID().

Indent __ieee754_rem_pio2()'s declaration consistently (its style was
made inconsistent with fdlibm a while ago, so complete this).

Fix __ieee754_rem_pio2()'s return type to match its prototype.  Someone
changed too many ints to int32_t's when fixing the assumption that all
ints are int32_t's.

The real solution would be to bring the whole nmount(2)

39fb1e8f88 Prevent the NFS client from losing MNT_ROOTFS on the root
file system.  In particular, stop overwriting mount point
flags in nfs_mountdiskless() because now they are set
elsewhere.  (They were _initialized_ by that function in
the 4.4BSD days, when mount structures were not allocated
in a centralized manner -- see rev. 1.1 of this file.)

Fix nfs_mount(), which happened to depend on the loss of
MNT_ROOTFS when it came to update handling.

Also note that mountnfs() no longer handles updates.  Now
they shouldn't reach this function, so printf a diagnostic
message if that happens due to a coding error.
