[svn-r15657] Purpose: fix bug 1286
Description: Added configure test to see if pointer alignment restrictions are enforced (as in dereferencing an unaligned pointer causes an error). Added code in H5Tvlen.c to avoid dereferencing unaligned pointers, conditionally compiled based on the configure test. Added test case in dtypes.c which would previously cause such machines to fail.
Tested: kagiso, smirom, linew (h5committest); linew64
