Commit this code before another patch becomes to difficult to follow.

  This patch does one thing, it changes the root path "/" to reflect an
  element count of Zero (0).  directory_walk will always accept the zero
  element (which sorts first, thankfully) on it's first go around.

  So, Unix will accept "/" when it's parsing it's first element "/".

  Dos/Win32 will accept "/" and "C:/" when they parse their first element,
  "C:/".  The root sorted first, so it behaves as users expect.

  The syntax "//" or "//machine" will be depreciated for now, the user
  needs to set up the extact "//machine/share/" that they want served
  on Win32.

note that a system trace of .var map processing still shows an
extra read() after we hit EOF the first time; we could make
use of the EOF flag in APR to avoid the read() or play with
mod_negotiation

  Revert this patch.  It indicates some fundamental brokenness with the
  apr_filepath_root() fn, which should simply return '/' for an absolute
  path on (most) unix, and advance the path pointer to the first non-'/'
  character  [if only Win32 and others were so simple ;-]

(ie, we can serve pages again :)  I'm still seeing issues with mod_include,

  I'm still not 100% certain on this test.  Regardless, it doesn't impact
