[svn-r10847] Purpose: Bug fix

Description: See details from Bug #213.  Family member file size wasn't saved
anywhere in file.  When family file is opened, the first member size determine
the member size.

Solution: This is the fourth step of checkin.  A test suit is added for h5repart,
including a program to generate the test files, a script file to run h5repart,
and a program to verify repartitioned files can be opened by the library.

There's a change from the first step of checkin.  Family name template is no
longer saved in the superblock because different pathname can make the name
different.

In the third step of checkin, h5repart has been modified.  If h5repart is used
to change the size of family member file, the new size(actual member size) is saved
in the superblock.

In the second step of checkin, multi driver is checked against the driver
name saved in superblock.  Wrong driver will result in a failure with an error message indicating
multi driver should be used.  This change includes split driver because it's a special case for multi
driver.

In the first step of checkin.  Family member size and name template(unused at this stage) are saved
in file superblock.  When file is reopened,the size passed in thrin superblock.  A different size
will trigger a failure with an error message indicating the right size.  Wrong driver to open family
file will cause a failure, too.


Platforms tested: h5committest and fuss.
