Added vector read / write support to the MPIO VFD, with associated
test code (see testpar/t_vfd.c).
Note that this implementation does NOT support vector entries of
size greater than 2 GB. This must be repaired before release,
but it should be good enough for correctness testing.
As MPIO requires vector I/O requests to be sorted in increasing
address order, also added a vector sort utility in H5FDint.c This
function is tested in passing by the MPIO vector I/O extension.
In passing, repaired a bug in size / type vector extension management
in H5FD_read/write_vector()
Tested parallel debug and production on charis and Jelly.
