The program will be installed as bintrans, uuencode, uudecode,
b64encode, and b64decode and will be responsible for running the coders
according to their historical behavior.
Additionally, bintrans will be able to take a parameter designating
the coder and accept all its options in this form:
bintrans <coder> [options]
and the behavior should be the same as if
<coder> [options]
was invoked.
This has the advantage that adding coders won't require installing them
as binaries.
Move uudecode files to uuencode since the latter is the one that
provides the manual page.

This more clearly differentiates system call arguments from integer
registers and return values. On current architectures it has no effect,
but on architectures where pointers are not integers (CHERI) and may
not even share registers (CHERI-MIPS) it is necessiary to differentiate
between system call arguments (syscallarg_t) and integer register values
(register_t).

This register set contains the values of the fsbase and gsbase
registers. Note that these registers can already be controlled
individually via ptrace(2) via MD operations, so the main reason for
adding this is to include these register values in core dumps. In
particular, this will enable looking up the value of TLS variables
from core dumps in gdb.
The value of NT_X86_SEGBASES was chosen to match the value of
NT_386_TLS on Linux. The notes serve similar purposes, but FreeBSD
will never dump a note equivalent to NT_386_TLS (which dumps a single
segment descriptor rather than a pair of addresses) and picking a
currently-unused value in the NT_X86_* range could result in a future
conflict.

script -r is useful for recording time-stamps of when output

we simply print the time-stamps to show when the output happened.
This is very useful for example, for analyzing boot time activity.
If the fmt provided contains no % characters the default
%n@ %s [%Y-%m-%d %T]
is used, which lends itself to analysis by tools as well as humans.

During distributeworld we call distribute on subdirectories, which in
turn calls installconfig. However, this recursive installconfig call
appends the distribution name (in these cases, "base") to DESTDIR. For
install(1) this works fine as its -D argument comes from the top-level
Makefile.inc1, which passes the original DESTDIR, thereby resulting in
the METALOG entry having the distribution name as a prefix representing
its true installed path relative to the root, but for the hand-rolled
entries they do not use install(1) and thus do not have access to what
the original DESTDIR was, resulting in the METALOG missing this prefix.
Thus, pass down the name of the distribution via a new variable DISTBASE
(chosen as Makefile.inc1 already uses that to convey this exact same
information to etc's distrib-dirs during distributeworld) and prepend
this to the handful of manually-generated METALOG entries. For the
installworld case this variable will be empty and so this behaves as
before.
Note that we need to be careful to avoid double slashes in the METALOG;
distributeworld uses find | awk to split the single METALOG up into
multiple dist.meta files, and this relies on the paths in the METALOG
having the exact prefix ./dist (or ./dist/usr/lib/debug).

Report, on a periodic basis, the I/O latencies the CAM I/O scheduler
computes. These times are only for the hardware portion of the I/O as
measured from the time the operation is scheduled with the SIM using
xpt_action() until the SIM reports it has completed with xpt_dine(). Any
time the I/O operation spends in a software queue is no included.
The P50 (median), P90, P99 and P99.9 statistics about the latency of
each of the read, write and trim operations that completed during the
polling interval are reported. If there are fewer than 2, 10, 100 or
1000 operations during the polling interval, no statistic is reported
and a single dash '-' is displayed.
The read, write and trim commands (either on the command line or at run
time) toggle display of these operations. The color command toggles
color (it defaults to on, like gstat). When color is enabled, unknown
statistics are reported in blue, high latency for a statistics is
reported in red, medium in magenta and low in green (as with gstat). The
med= and hi= commands can set these latency thresholds.
Limitations: The entire sysctl space for all the devices is walked for
each polling period. This should be optimized to remember the OIDs and
only do such polling with the xpt generation changes. There is also no
way to filter devices displayed. This command only works on physical
devies that are connected to SCSI, ATA or NVME sims as those are the
only ones that are instrumented in the CAM I/O scheduler (the
CAM_IOSCHED_DYNAMIC option must be in the kernel, and the dynamic
scheduler can't be disabled).
