[svn-r2600] Purpose:
Implemented new feature
Description:
Added data sieve buffering code to raw I/O data path. This is enabled for
all the VFL drivers except the mpio & core drivers. Also added two new
API functions to control the sieve buffer size: H5Pset_sieve_buf_size() and
H5Pget_sieve_buf_size().
Platforms tested:
Solaris 2.6 (i.e. baldric)
