serialize/unserialize vector improvement
...hat improves the performance
of the serialize/unserialize interface for vector types. The current
implementation: a) invokes the R_XDREncode operation for each element
of the vector type, and b) uses a switch statement to determine the
stream type for each element of the vector type. I've added
R_XDREncodeVector/R_XDRDecodeVector functions that accept N elements
at a time, and I've reorganized the implementation so that the stream
type is not queried once per element.
In the following microbenchmark (below), I've observed performance
improvements of about x2.4. In a real benchmark that is using t...
