示例1: _Rename
/*! \brief Renames the BEntry to path, replacing an existing entry if clobber is true.
NOTE: The BEntry must refer to an existing file. If it is abstract, this method will fail.
\param path Pointer to a string containing the new name for the entry. May
be absolute or relative. If relative, the entry is renamed within its
current directory.
\param clobber If \c false and a file with the name given by \c path already exists,
the method will fail. If \c true and such a file exists, it will
be overwritten.
\return
- \c B_OK - Success
- \c B_ENTRY_EXISTS - The new location is already taken and \c clobber was \c false
- \c B_ENTRY_NOT_FOUND - Attempted to rename an abstract entry
- "error code" - Failure
