[svn-r13138] Description:
Auto-detect the support for the posix_memalign routine and disable the direct I/O VFD if posix_memalign is not supported. This should allow direct I/O to be auto-detected and disabled on FreeBSD. (Direct I/O itself works fine, but doesn't have the alignment requirements on FreeBSD that it has on Linux, so the code would have to be re-worked to not use posix_memalign and we don't need to support that right now). Tested on: FreeBSD/32 6.1 (duty) Linux/32 2.4 (kagiso)
