, where blob.Storage.PutBlob gets a list of slices and writes them sequentially
* performance: added gather.Bytes and gather.WriteBuffer
They are similar to bytes.Buffer but instead of managing a single
byte slice, they maintain a list of slices that and when they run out of
space they allocate new fixed-size slice from a free list.
This helps keep memory allocations completely under control regardless
of the size of data written.
* switch from byte slices and bytes.Buffer to gather.Bytes.
This is mostly mechanical, the only cases where it's not involve blob
storage providers, where we leverage the fact that we don't need to
ever concatenate the slices into one and instead we can do gather
writes.
