s3/php: update to 1.5? version of API

Something like v1.5 of the Amazon PHP library requires the AmazonS3
constructor to be given an array of parameters rather than using
the globals.  More research needs to happen, and particularly
about the v2 API, but this might solve someone's problem with
v1.5 while we do that research.

rbd-fuse: add simple RBD FUSE client

Currently written in C on FUSE hi-level interfaces, so error reporting
could be better.  No serious work done for performance.  But it's
usable as it stands.

Specify -c <conf> and a mountpoint, and images show up as files in
that mountpoint.  You can create new images; they'll be created
with attributes stored in xattrs:

	user.rbdfuse.imagesize: default 1GB
	user.rbdfuse.imageorder: default 22
	user.rbdfuse.imagefeatures: default 1 (layering)

Images may be truncated or extended by rewriting.  Currently
once an image is opened, it's not closed, so it can't be deleted
or changed outside of the fuse path.
