There is a growing number of path concatenation cases, each built on some memory allocation scheme and some variant of sprintf. Introduce a pathbuf type and a few primitive operations to reset the pathbuf, clone a pathbuf, push a path/filename to the pathbuf, get the path, and truncate the path by dirname(). Also provide a convenient qdl_path_exist() operation to test if the pathbuf refers to an existing file. Signed-off-by: Bjorn Andersson <bjorn.andersson@oss.qualcomm.com>
