I really don't think any other definition of pstrndup() makes sense --

especially since it always allocates n+1 bytes of memory, even if I go
back to its original definition.  And on examination, all of our uses
of pstrndup() are cases where we want a substring of another string, and
we know the substring is of a certain length.  So speed up pstrndup() by
using memcpy().  (This small change was worth another 50% performance
boost when I tested it on test-util-uri.)
