e37e2782a9 Only use major()/minor() if they are available in tar(1)
Otherwise silently ignore them in the archive case.  This is the
same in principle as what we do in the unarchive case.

fb12183c52 Add strlcpy()/strlcat()
Refactor recurse() routine in preparation to moving tar(1) over
to use it instead of the ftw() interface.

c83aef2cda Use preprocessor conditionals to check if makedev() is present
makedev() is not portable and is typically implemented as a
macro.  If it exists use it, otherwise silently ignore character
and block devices.

203b52c38a Use getpriority()/setpriority() instead of deprecated nice()
This is now similar to how renice(1) is implemented.

43057f3a39 Remove mknod(1) from sbase
mknod(1) is not POSIX and it is not portable so it should be
in ubase instead of sbase.

1bc2296bac Double NARGS
I just ran a simple one-liner[1] to find the average filepath
length on my system (absolute paths) and that came up with a value
~90 characters.  Assume this is out by a factor of two, we still
have potentially 5000 more arguments that we can put into the buffer.

Surely one might run xargs(1) on something that is not a filename.
We just choose to accomodate the common use-case as much as possible.

[1] find / 2>/dev/null | awk '{print length($0)}' \
	| awk '{a+=$1}END{print "average filepath length: ",a/NR}'

fbd786d22a Correctly handle leftover input
We cannot rely on ungetc() pushing back more than 1 character
reliably on all systems, so just note if we have leftover input and
process it in the next run.
