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.
