Instead of having multiple kyua libraries, just include the files as part
of usr.bin/kyua. Previously, we would build each kyua source up to four
times: once as a .o file and once as a .pieo. Additionally, the kyua
libraries might be built again for compat32. As all the kyua libraries
amount to 102 C++ sources the build time is significant (especially when
using an assertions enabled compiler). This change ensures that we build
306 fewer .cpp source files as part of buildworld.

Banner appeared in the 6th edition of AT&T Research unit. It was
subsequently on all the Berkeley tapes, as well as PWB, System III and
System V. The PWB/AT&T and BSD banner programs were different, and the
current FreeBSD banner program shares many elements of the 3BSD one,
though the font has changed.

Dirname(1) first appeared in System III, and was later picked up in

This results in a significant improvement in the runtime of sort(1) when
radix sort cannot be used. This comes at the expense of increased
memory usage, but this is small relative to sort's overall memory usage.

Deciding whether to combine two values to a 64-bit one should be based on
the process ABI, and not dependent on whether truss is compiled for an
LP64 ABI. This is a follow-up cleanup for D27625. I found this while
looking for uses of the `__LP64__` macro (since using this is wrong for
CHERI systems).
Test Plan: truss still works. Since I tested on AMD64 and all syscalls
in the trace have their quad argument last there was no difference
in the output. Should fix output for compat32 on MIPS64 though.

Attempting to parse the output as UTF-8 exposed an out-of-bounds read
in vis(3) (see https://reviews.freebsd.org/D30771). However, I don't
think it makes much sense to decode this output at all. Additionally,
passing one byte at a time will almost certainly result in incorrect
output for multi-byte characters.

Currently IREMOTE assumes that every value is (initially) a pointer to a
long. This is true for NUMBERs, but false for STRINGs, which are instead
pointers to pointers, though on ILP32 and LP64 systems these happen to
have the same representation, but this is still a strict aliasing
violation, and of course breaks on systems where the representations are
not the same, such as CHERI. We do not currently have any BOOLs (short,
curiously) or CHARs used with IREMOTE, though the code should not be
relying on that.
This removes the unused setaddress macro, and the now-unused address
macro due to the above issue.

Whilst all FreeBSD architectures have the same representation for
intptr_t and long (even if the former is int on ILP32 architectures),
this is more general and correct, and on CHERI they are not the same so
warnings are generated by default for integer-to-pointer casts that
aren't via (u)intptr_t.

Paste's man page contains an example for a reimplementation of
nl(1). This example uses the command line
sed = myfile | paste -s -d '\t\n' - -
in order to concatenate consecutive lines with an intervening tab.
However, the way the example uses the switches -s and -d and two `dash`
input files is redundant. There are in fact two equivalent but simpler
ways to achieve the desired result:
sed = myfile | paste -s -d '\t\n' -
uses the same style as the previous example, while
sed = myfile | paste - -
is arguably even simpler and illustrates the final sentence of the

- report Grater-or-EQual (GEQ) bandwidth as soon as it reaches

Custom implementation of callouts was removed. There is no
point of doing calout-wheel here as generic callouts are
doing exactly the same. The performance is not critical
for such reporting, so the biggest concern should be
to have a code which can be easily maintained.
This is ia preparation for locking rework which is highly inefficient.
