Add support for '.' and '..' entries in sqfs_dir_reader_t
Two flags are added to the dir reader API, one for the create function
that the dir reader should report those entries and one to the open
function to suppress that if it was enabled.
To implement the feature, a mapping of visited directory inodes is
maintained internally, that mapps inode numbers to inode references.
When opening a directory, state is maintained to generate the fake
entries for '.' and '..'. Since all the other functions are based on
the open/read/rewind API, no alterations need to be made. The tree
scan function is modified, to use the suppress flag, so it does not
accidentally catch those entries.
