54af59dd3a It was pointed out[0] that ctags(1) uses some potentially dangerous 
system(3) calls where user-supplied data is used with no sanity
checking. Since ctags(1) is not setuid and is not likely to be used
in a privileged situation, this is not a big deal. However, the
fix is relatively easy and less ugly than the current code, let's be
safe. (I'm sure there are about 2^134 other system(3) calls like this
out there.)

7a80636e7f Include local copies of fts.c and fts.h to be used ONLY on non-FreeBSD 
systems.  The fts.h here is an exact copy of include/fts.h (except for
an initial explanatory comment and the revision tags, of course).  The
fts.c here is slightly modified from lib/libc/gen/fts.c so it can
compile correctly on non-FreeBSD systems.

e3af2353c4 A security issue: An archive containing a symlink to another 
directory, then a file with that symlink as a prefix can drop a file
outside of the current directory, which can be a security hole.

Plug this hole by refusing to extract files if a prefix of the
pathname is a symlink.  The -P option disables this check.

5aa078d988 Speed up hardlink detection by using a self-sizing hash 
table rather than the old linear list search.

On my "hardlink detection torture test", this reduced
user time from 4700 seconds down to 4.2 seconds
and wallclock time from 1:24:48 down to 1:08.
(Yes, that's over one THOUSAND times reduction in user time. ;-)
In the worst case, the new code doubles peak memory usage,
though it could actually reduce memory usage in many cases.

b07f071cf0 Include <sys/proc.h> instead of depending on namespace pollution in 
<sys/user.h> for the definition of TDF_SINTR.  Fixed anachronous
spelling of TDF_SINTR in a comment

Demangled VCS ids.  There were 2 misplaced copies of $FreeBSD$ and of
the include before it.  The vendor id infrastructure was edited.

Fixed the only other remaining style bug since rev.1.1 (expansion of
struct member names made a line too long).
