[svn-r21533] Description:
Bring r21442 and r21529 from trunk to 1.8 branch: Add new API routines for querying if collective raw data I/O was actually performed collectively. Tested: Linux/32 2.6 (jam) (h5committested on trunk)

+/* Function: test_actual_io_mode
+ *
+ * Purpose: tests one specific case of collective I/O and checks that the
+ * actual_chunk_opt_mode property and the actual_io_mode
+ * properties in the DXPL have the correct values.
+ *
+ * Input: selection_mode: changes the way processes select data from the space, as well
+ * as some dxpl flags to get collective I/O to break in different ways.
+ *
+ * The relevant I/O function and expected response for each mode:
+ * TEST_ACTUAL_IO_MULTI_CHUNK_IND:
+ * H5D_mpi_chunk_collective_io, each process reports independent I/O
+ *
+ * TEST_ACTUAL_IO_MULTI_CHUNK_COL:
+ * H5D_mpi_chunk_collective_io, each process reports collective I/O
+ *
+ * TEST_ACTUAL_IO_MULTI_CHUNK_MIX:
+ * H5D_mpi_chunk_collective_io, each process reports mixed I/O
+ *
+ * TEST_ACTUAL_IO_MULTI_CHUNK_MIX_DISAGREE:
+ * H5D_mpi_chunk_collective_io, processes disagree. The root reports
+ * collective, the rest report independent I/O
+ *
+ * TEST_ACTUAL_IO_MULTI_CHUNK_NO_OPT_COL:
+ * H5D_mpi_chunk_collective_io_no_opt, each process reports collective I/O
+ *
+ * TEST_ACTUAL_IO_MULTI_CHUNK_NO_OPT_MIX_DISAGREE:
+ * H5D_mpi_chunk_collective_io_no_opt, processes disagree
+ * (collective and mixed I/O)
+ *
+ * TEST_ACTUAL_IO_LINK_CHUNK:
+ * H5D_link_chunk_collective_io, processes report linked chunk I/O
+ *
+ * TEST_ACTUAL_IO_CONTIGUOUS:
+ * H5D_contig_collective_write or H5D_contig_collective_read
+ * each process reports contiguous collective I/O
+ *
+ * TEST_ACTUAL_IO_NO_COLLECTIVE:
+ * Simple independent I/O. This tests that the defaults are properly set.
+ *
+ * TEST_ACTUAL_IO_RESET:
+ * Perfroms collective and then independent I/O wit hthe same dxpl to
+ * make sure the peroperty is correctly reset to the default on each use.
+ * Specifically, this test runs TEST_ACTUAL_IO_MULTI_CHUNK_NO_OPT_MIX_DISAGREE
+ * (The most complex case that works on all builds) and then performs
+ * an independent read and write with the same dxpls.
+ *
+ * It may seem like TEST_ACTUAL_IO_MULTI_CHUNK_NO_OPT_IND and
+ * TEST_ACTUAL_IO_MULTI_CHUNK_NO_OPT_MIX have been accidentally
+ * left out. This is intentional; the other test cases sufficiently
+ * cover all cases for Multi Chunk No Opt I/O.
