This commit adds hole-punching support to the truncate(1) utility. If
the option -d is specified, truncate(1) performs zeroing, and if
possible hole-punching in case the operation is supported by the
underlying file system of the specified files.

Merge commit 2f57ecae4b
This is a new major release with a number of changes and extensions:
- Limited the number of temporary numbers and made the space for them
static so that allocating more space for them cannot fail.
- Allowed integers with non-zero scale to be used with power, places,
and shift operators.
- Added greatest common divisor and least common multiple to lib2.bc.
- Made bc and dc UTF-8 capable.
- Added the ability for users to have bc and dc quit on SIGINT.
- Added the ability for users to disable prompt and TTY mode by
environment variables.
- Added the ability for users to redefine keywords.
- Added dc's modular exponentiation and divmod to bc.
- Added the ability to assign strings to variables and array elements
and pass them to functions in bc.
- Added dc's asciify command and stream printing to bc.
- Added bitwise and, or, xor, left shift, right shift, reverse,
left rotate, right rotate, and mod functions to lib2.bc.
- Added the functions s2u(x) and s2un(x,n), to lib2.bc.

yacc makes awkgram.h. However, one true awk includes awkgram.tab.h, so
we link to for the builds. Make sure that we consistently link to it.
Also, restore the awkgram.tab.h dependency to maketab. It should not
have been deleted, despite apparently making meta build on stable/12
work. The important missing arc was proctab.c's dependence on
awkgram.tab.h.

proctab.c is generated from awktab.h, so needs to depend on it.
maketab does not depend on awktab.h, and gets the maketab.c dependency
automatically, so remove them both.
Normally, these don't matter. However, for a meta build, they can cause
us to build maketab twice (once host, once for target) resulting in a
binary that can't run on the host due to proctab.c racing maketab in
parallel legs. In stable/12, this was a reliably lost race, while in
main I've been unable to trigger the race at all (maybe due to dirdep
changes making main more robust).

FreeBSD will convert "0x12" from hex and print it as 18. Other awks will
convert it to 0. This extension has been removed upstream, and will be
removed in FreeBSD 14.0.
FreeBSD used to set the locale on startup, and make the ranges use that
locale. This lead to weird results like "[A-Z]" matching lower case
characters in some locales. This bug has been fixed.

Upstream is poised to deprecate the -Ft wart in one true awk. None of
the other awks do this, and the gawk maintainer says that he's had no
requests for it in gawk in 30 years maintaining it. github can find a
few instances of it in the wild. As such, warn that it's deprecated and
will go away in the future.

The current description of the FS is true, but only part of the
truth. Add information about single characters and note that FS="" is
undefined by the standard, though the two other awk implenetations (mawk
and gawk) also have this interpretation.

When the quite (-q) flag is provided, we don't expect any output.
Currently, the behavior is broken:
$ grep -cq flag util.c
1
$ grep -cs flag util.c
55
First of all, we print a number to stdout. Secondly, it just returns
0 or 1 (which is unexpected). GNU grep with c and q flags doesn't
print anything.

o Set close-on-exec flag for file and pipe redirects that aren't std*
o lots of little fixes to modernize ocde base
o free sval member before setting it
o fix a bug where a{0,3} could match aaaa
o pull in systime and strftime from NetBSD awk
o pull in fixes from {Net,Free,Open}BSD (normalized our code with them)
o add BSD extensions and, or, xor, compl, lsheift, rshift (mostly a nop)
Also revert a few of the trivial FreeBSD changes that were done slightly
differently in the upstreaming process. Also, our PR database may have
been mined by upstream for these fixes, and Mikolaj Golub may deserve

UBSan complains about out-of-bounds accesses for zero-length arrays. To
avoid this we can use flexible array members. However, the C standard does
not allow for structures that only contain flexible array members, so we
move the length parameters into that structure too.

Fixes: 2eb9ad427475190ei ("Simplify and speed up the kyua build")
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.
