[VOTE] apr 1.7.2 and apr-util 1.6.3

I hosed 1.7.1/1.6.2 and the archives have -rcX in them at the top
level.  I would like to call for an expedited vote to replace them
with version bumps.  I will proceed once we get 3 binding +1.

I have re-tagged because I think the consensus will be that updating
the tarballs and signatures is too confusing.

candidates are here:

For the release of apr-1.7.2 AND apr-util-1.6.3
  [  ]  +1 looks great
  [  ]  -1 something is broken
