[svn-r26326] Merge of r26275 from the trunk
- Updated configure.ac so that the direct VFD can now be built without specifying _GNU_SOURCE, etc. on the command line. - The direct VFD is now disabled by default. It was previously enabled, but the configuration script couldn't configure it properly, making it a moot point. Fixes: HDFFV-9057, HDFFV-7567, HDFFV-9088, HDFFV-7566 Tested on jam (configure/make in various configurations only)

+ - Direct VFD configure behavior
+
+ The configure options for Linux now allow the direct VFD to built
+ without passing additional compiler options/defines like _GNU_SOURCE.
+ Passing --enable-direct-vfd is now all that is needed to enable
+ the feature.
+
+ The direct VFD is now disabled by default since it is intended for
+ specialized audiences. It was previously enabled by default, but the
+ configure script did not set correct POSIX levels, etc. making this
+ a moot point.
+
+ Note that the direct VFD can only be configured on Linux when
+ the O_DIRECT flag to open()/create() and posix_memalign() function
+ are available. This is unchanged from previous behavior.
