[svn-r11490] Purpose:

Bug fix

Description:
    Fix "double root open" bug and apply same fix to datasets & named datatypes.

    Also fix bug in symbol table entry lookup code that would "transfer" an
object from one file handle to another file handle when the two file handles
were opened on the same actual file.

Platforms tested:
    FreeBSD 4.11 (sleipnir)
    Too minor to require h5committest
