[svn-r15561] Description:

	Update extensible array code with function to open an existing earray,
add more tests and avoid running the test when core/split/family/multi VFDs
are used.

	Clean up fractal heap test code a bit and expand some of the tests a
little bit also.

Tested on:
        Mac OS X/32 10.5.4 (amazon) in debug mode

                                in production mode
        FreeBSD/32 6.3 (duty) in debug mode
        FreeBSD/64 6.3 (liberty) w/C++ & FORTRAN, in debug mode
