disk.c and friends

hi all,

i've (rediscovered!) the mess that is disk.c and how various subsections
handle disk IO. In a nutshell, there's lots of stuff in disk.c that implements
async disk IO, but nothing ever uses it these days.

I'd like to:

* tidy up disk.c to simply do sync disk IO calls,
  and remove all of the async stuff (queueing,
  write combining)
* rework things like logfile.c which use file_open()
  but don't use file_write() for some reason

.. and throw it in squid-HEAD.

I also note that in the past, before the great storeio abstraction
by duane, when async-io was compiled in you'd get async logfile
writing. (hence the write combining..) does anyone here see a need
for this to come back at all? Does anyone ever remember logfile
writing being faster with it turned on?
