Benjamin M. Schwartz c7cf12703d quicvarint: tolerate empty reads of the underlying io.Reader (#5275) ...

* Tolerate empty reads in `quicvarint.Read`

Currently, `quicvarint.Read` misinterprets an empty read (`n==0`)
as a single zero byte.  While empty reads are "discouraged" in
the `io.Reader` interface, they do sometimes happen, especially
when using `io.Pipe()`.

This change tolerates empty reads, adds a corresponding unit test,
and also includes some additional test coverage related to empty
capsules

* minor test refactor
