/*
* The purpose of this test is to verify if a virtual file driver can handle:
* a. Large file (2GB)
* This should exceed 32bits I/O system since offset is a signed
* integral type (in order to support negative offset with respect to
* end of file).
* b. Extra Large file (4GB)
* This definite exceeds 32bit I/O and file systems.
* c. Huge file (tens of GB)
* This verifies the HDF5 library handles big logical file size
* correctly.
* In practice, if a VFD can handle a big file size, there is no need to
* test the smaller file sizes. E.g., If it can handle the Huge file,
* there is no need to test the Extra large or Large files. Therefore the
* test starts with larger size files and continues to test the smaller size
* files only if the large sige file tests have failed.
*
* Another consideration is that even if a VFD is capable to handle a
* huge file but it is likely to take a long time to write every byte
* of a huge file. E.g., a simple workstation may have disks of write
* speed of 10MB/sec. A huge file of 30GB will take about an hour to
* write it. Therefore, this test will run the huge file test only if the
* underlying file system supports sparse file. (A Sparse file here means
* that disk space is allocated only when the contents are actually written.
* E.g., If one creates a new file, seeks forward 10 million bytes, writes
* 1 bytes and closes the file, then a sparse file, will show file size of
* 10 million bytes but actually uses only couple disk blocks, much smaller
* than the formal file size.)
*
* One more consideration is that we want to distinguish an HDF5 library
* failure from some system limits such as current free disk space or user
* disk space quota. Therefore, the test will first attempt to verify no
* such limits exist before running the actual VFD tests.
