80a4e936b5 extend the "tout" column to 5 characters, it's really common on a modern 
machine to have eg, build output way more than 9999 chars/sec.

this doesn't affect the default disk list on an 80-char wide screen.

bdd303d7a7 support fnmatch(3) patterns for disknames. eg, "iostat wd*" works now. 
update the default disk number selection to note that it uses the current
terminal size to fit disks, not hard coded 4.

5637a88e80 Maintain 5-character width of MB/s column by dynamically adjusting the 
decimal precision.

This should work until disk transfer rates exceed 99999 MB/s.

53211cb1ae Since the swapping of tk_nin and tk_nout was moved to its own 
function (tkswap()), actually call this function.

Fixes problems where the tin/tout fields showed total tty IO since
boot instead of just what has happened in the last second.

134561f7df - convert header() away from a signal function (it does all sorts of stdio 
and more) and use a little sig_header() helper.
- in selectdrives() make sure we don't overwrite some arrays.  this makes
"iostat 1" work again on my really wide screens where defdrives (number that
can fit) was > ndrives (number of drives), rather than dump core trying to
print (char *)1...

c71be29ffd Use the terminal width to choose the default number of drives listed.

70378aeac7 - Account the number of lines consumed so that -xw displays header 
frequently enough.
- As we are initializing dk_select to 0 (via dkinit), no need to check it.
- Re-order the code in display() to highlight the fact that -x is
  exclusive with others.
- If user really specified some drives and none of them are found,
  just bail out rather than falling back to default behaviour.
- Other misc. cosmetic changes while I'm here.

3cf4c73d05 iostat(8) and systat(8) support for separate read/write disk statistics. 
"iostat -x" now shows these (ala linux/solaris), but this is only splitting
the read/write bytes/transactions, not adding any new metrics.  "systat
iostat" now has two new commands to switch between combined/separate mode
for both it's numbers & bar modes.

f80c7eebd7 Since the KERN_CP_TIME sysctl reports total clock ticks across all 
cpus and hz is measured in ticks per cpu, divide tick count by ncpu to
determine elapsed time since last sample.

Fixes I/O rate deflation observed on multiprocessors.
