hdf5_ep

[svn-r6808] Purpose:
code warrior fix

Description:
eliminate the CW failure on getname.c
restrict the H5_NO_FILE_SHARING just to the test file_close of testhdf5 test

Solution:
the CW failure on getname.c  can be eliminated if a unmount of the file is made before closing it
on tfile.c the failure is due to the file sharing flag of CW, and the test is maintained as before

Platforms tested:
Windows 2000 (octopus)
Linux 2.4 (rockaway)
SunOS 5.7 (arabica)
IRIX 6.5 (modi4)
