Convert ranger and clients to vrange.

Convert ranger and clients to vrange.

Finally, the meat of the work.  Convert ranger and associated clients
to vrange.

Everything's relatively mechanical given the previous patches.  I did
include a minor cleanup in the edge code.  There's no need to check
that the type of the switch is an integer as non-integer switches are
invalid.  I verified this with an appropriately coded assert.

Tested on x86-64 & ppc64le Linux.
