especially on strings passed from argv; rename system() to exec_shell(),
and make it static; use strlcpy() and make sure it works; use proper
type (size_t) to be passed to malloc()/realloc().
Use getusershell() to make sure the SHELL environment variable passed is
safe to use. Add new option -s to allow anal users to pass things like
perl; this option is here along with getusershell() checking since the
such checking is only intended to affect things like suidperl that might
call apply(1).

all devices are by default known by their 'cooked' name, so
my change was wrong. I thought it was a hangover from old 'block
tape device' support which hasn't worked (if it ever did) since
v6/PWB.
So, the default tape name is now the same as Linux. Far out, man....
actually NOT '.' and '..'. Apparently this isn't the case when accessing
a directory via XFS over NFS on SGI systems. Since I don't have access to
an environment like that, this will sit out in -current for at least six
weeks. However, the patch proposed by the submitter seems acceptable, so
I've decided to commit it to the tree, in the hope that it will solve some
problems without bringing up others.

o Fix up style violations of various sorts.
o Remove redundant normalization of hertz variable, as the sysctl handler
does this work (unlike when kread was used).

no longer contains kernel specific data structures, but rather
only scalar values and structures that are already part of the
kernel/user interface, specifically rusage and rtprio. It no
longer contains proc, session, pcred, ucred, procsig, vmspace,
pstats, mtx, sigiolst, klist, callout, pasleep, or mdproc. If
any of these changed in size, ps, w, fstat, gcore, systat, and
top would all stop working. The new structure has over 200 bytes
of unassigned space for future values to be added, yet is nearly
100 bytes smaller per entry than the structure that it replaced.
