ping: use CLOCK_REALTIME for ICMP Originate Timestamp
RFC 792 defines the ICMP Originate Timestamp field as milliseconds
since midnight UTC. However, ping(8) currently derives this value
from CLOCK_MONOTONIC, which represents time since an unspecified
starting point and is not related to UTC.
The issue was introduced by commit 1ad76f1b6047, which replaced
gettimeofday(2) with clock_gettime(CLOCK_MONOTONIC) for timekeeping
in ping(8).
Fix this by using CLOCK_REALTIME when generating the ICMP originate
timestamp.
Before:
$ ping -Mt -c1 127.0.0.1
ICMP_TSTAMP
PING 127.0.0.1 (127.0.0.1): 56 data bytes

llvm-*: Move all LLVM_BINUTILS symlinks to toolchain package
Some of the LLVM binary utilities were included in the Clang package
(because they did not set an explicit PACKAGE).
Add a new Makefile under clang/toolchain to create the symlinks and man
links for ar, c++filt, nm, and so on (without the llvm-* prefix) when
LLVM_BINUTILS is enabled (as it is by default).

namei: Preserve ABI root for absolute symlinks before fallback
D40479 changed namei() so that an absolute symlink target
encountered during an ABI-root lookup restarts from the native root.
This helps the native fallback case, but it also makes successful
lookups inside an ABI root escape that root while following absolute
symlinks.
Only switch absolute symlink lookup to the native root after namei()
is already in the restarted/native fallback pass.
Do not mark the lookup as restarted merely because an absolute
symlink was encountered while still resolving inside the ABI root.
This preserves the intended native fallback behavior while keeping
absolute symlinks within a successfully resolved ABI-root path in
the ABI namespace.

replace it with a similar message for UFS. While here, reword that note
to be a bit clearer.

linux: Implement setfsuid(2) and setfsgid(2) as no-ops
These system calls exist to decouple the Linux filesystem credentials
from the effective credentials, avoiding signal exposure during
privilege transitions.
The signal permission model that motivated this was revised
in Linux 2.0, making these syscalls obsolete for new applications.
Implement both syscalls as no-ops that return the current effective
UID/GID as the previous filesystem UID/GID.
Linux returns the previous filesystem UID/GID for these syscalls
with no error indication.
Same for the equivalent setfsuid16() & setfsgid16() system calls.

stat: fix use of devname(3)
Besides being a little hard to parse through visually, this had its own
bug of inspecting st->st_mode to determine what to pass to devname(3),
which is only correct for st_rdev.
For st_dev, you're likely to be looking at files or directories and
attempting to assess what device they're located on, so the mode is
meaningless- we just have to assume that our filesystems are on
character devices and attempt to resolve st_dev as such.
