udf: Make stat on symlink report symlink length as st_size
UDF encodes symlinks in a more complex fashion and thus i_size of a symlink does not match the lenght of a string returned by readlink(2). This confuses some applications (see bug 191241) and may be considered a violation of POSIX. Fix the problem by reading the link into page cache in response to stat(2) call and report the length of the decoded path. Signed-off-by: Jan Kara <jack@suse.cz>
