[svn-r19499] Description:
Bring r19498 from trunk to 1.8 branch:
Optimize the vector-vector memcpy() routine even further, for a total
of ~2x speedup. :-)
Make a generic vector-vector operation routine and convert other
vector-vector read & write routines to use generic routine instead of multiple
copies of the basic algorithm.
Tested on:
FreeBSD/32 6.3 (duty) in debug mode
(h5committested on trunk)
