fsal_posixdb_buildOnePath: Build the path of an object with only one Path in the parent table (usually a directory).

Parameters:
p_conn(input) Connection to the database
p_handle(input) Handle of the object we want the path
path(output) Path of the object
Returns:
- FSAL_POSIXDB_NOERR, if no error. Another error code else.

fsal_posixdb_deleteParent: Delete a parent entry. If the handle has no more links, then it is also deleted. Notice : do not use with a directory

Parameters:
p_conn(input) Connection to the database
id(input) ID part of the handle of the object
ts(input) Timestamp part of the handle of the parent directory
