libsqfs: bring sqfs_file_t in line with stream API

Rename the open function to sqfs_file_open, use an argument for the
return pointer and pass back and error number on failure. Also add
an inermediate function to open an sqfs_file_t using a handle, similar
to the stream API. The get_file_size function is moved to the native
wrappers and some of the implementation is cleaned up a little.
