cluster/stripe: handle short writes and errors in writev callback
cluster/stripe write callback handling is broken in the event of
server side errors and short writes due to crudely summing up the
return values from each node. This can produce incorrect results
or cause an application to rewrite the wrong portions of a buffer
in an attempt to handle this condition.
Modify cluster/stripe writev handling to record the requested size
of each write and use this data to return the number of consecutive
bytes written from the original request. This allows an application
to retry a write at the point of error (and potentially consume
said error).
