[svn-r11057] Purpose:

    Bug fix

Description:
    Correct error where the dataset sieve buffer was inadvertantly disabled,
resulting in poor raw data I/O performance for certain I/O patterns.

Solution:
    Hook dataset sieve buffer size setting back up.

Platforms tested:
    FreeBSD 4.11 (sleipnir)
    Solaris 2.9 (shanti)

 /*-------------------------------------------------------------------------
+ * Function:	H5F_sieve_buf_size
+ *
+ * Purpose:	Replaced a macro to retrieve the dataset sieve buffer size
+ *              now that the generic properties are being used to store
+ *              the values.
+ *
+ * Return:	Success:	Non-void, and the dataset sieve buffer size
+ *                              is returned.
+ *
+ * 		Failure:	void (should not happen)
