This s part of an import of the PVR-250 driver. Originally it was
calleed pvr250-setchannel, but it seems better to improve this program
to work for any tuner card, so I'm starting with a more generic name.
That shouldn't mislead anybody: currently the program only works with
the (yet to be committed) cxm driver.

* Add rules to usr.bin/top/Makefile that rebuilds a new sigconv.h
header which matches the correct signal set from the build-time

get stale once changes are made to the header).
* Remove the old sigconv.h header, now that it is autoupdated at
build time.
* Various Makefile style fixes (the committed Makefile was kindly
submitted by Ruslan):
- Reorder .PATH, PROG, SRCS and CFLAGS to match style.Makefile(5)

- Add entries to CLEANFILES near the rules that generate the
respective files.
- Move the explicit rule which builds top.1 after the implicit

wildcard specifications. Earlier the only wildcard syntax
was "-j 0" for "any jail". There were at least
two shortcomings in it: First, jail ID 0 was abused; it
meant "no jail" in other utils, e.g., ps(1). Second, it
was impossible to match processed not in jail, which could
be useful to rc.d developers. Therefore a new syntax is
introduced: "-j any" means any jail while "-j none" means
out of jail. The old syntax is preserved for compatibility,
but now it's deprecated because it's limited and confusing.
Update the respective regression tests. While I'm here,
make the tests more complex but sensitive: Start several
processes, some in jail and some out of jail, so we can
detect that only the right processes are killed by pkill
or matched by pgrep.

behavior of sockstat(1) will still be to show "udp", "tcp" and
"divert" protocols, but we can now provide a (comma-separated)
list of protocols, as in:
% sockstat -P tcp
to list only TCP sockets, or we can filter more than one protocol
by separating the protocol names with a comma:
% sockstat -P tcp,udp
Protocol names are parsed with getprotobyname(3), so any protocol
whose name is listed in `/etc/protocols' should work fine.

priority class and use this to:
- print "-" instead of a garbage value for ithreads. Print "-" instead
of the unused nice value for kthreads which are (mis)classified as
PRI_TIMESHARE. For such threads, the nice value can be set to nonzero
by root, but it is never used (at least by the 4bsd scheduler). For
ithreads, we didn't even print the unused value.
- print "i<priority>" and "r<priority>" instead of a biased "<priority>"
for idletime and realtime threads, Here <priority> is the priority
parameter to idprio/rtprio(1). Just add the prefix and remove the
bias for now. <priority> has been stored indirectly in the kernel
since 2001/02/12, and even the kernel cannot recover the original
value in all cases. Here we need to handle more cases than pri_to_rtp(),
but actually handle fewer cases, and end up printing garbage after
a thread changes its current priority while in the kernel.
- for idletime and realtime threads, if they are kthreads then add a prefix
of "k" to the previous string.
- for idletime and realtime threads, if they in the FIFO scheduling class

parts of the string are sure to fit unless <priority> is garbage).

system that don't have audit framefork compiled into kernel or ia32 binary
on amd64 system will result in SIGSYS. There is one place in su.c itself
where it tries to check for errno != ENOSYS, but it has been a nop since su
does not catch SIGSYS anyway. There are few other places in libbsm,
where attempt to invoke audit syscal would result in SIGSYS if no audit
support is present in the kernel, so that the only reliable method for
now is to disable SIGSYS completely in the case when BSM is compiled in.
In the long run, both direct invocation of audit-related syscalls and
libbsm should be made more intellegent to handle the case when BSM is not
compiled into the kernel gracefully.

o When stat(2) fails (i.e. the file has been moved) there's no new
file with the same name yet, so keep showing the file that's open.
This yields the same behaviour as -f, for which we don't stat(2).
o When a new file with the same name has been created (i.e stat(2)
succeeds but the inode or device numbers differ from the opened
file), show any new lines in the opened file (i.e. the old or
rotated file) before reopening the new file.
These changes fix the observed behaviour that tail(1) doesn't show
the very last lines of the rotated (log) files.
