We can't change the mod of symlinks and hence AT_SYMLINK_NOFOLLOW is
not supported by chmod(2 -> RTFM!).
The solution is to not use that flag and simply skip symlinks.

Do not try to change the nameless root node which is mapped to the
output directory.

cleanup: unify all the code that reads squashfs images2019-08-05T15:45:59+00:00David Oberhollenzerdavid.oberhollenzer@sigma-star.at2019-08-05T15:38:08+00:00urn:sha1:88f75857702bcc6a2a423570912140c125ec518a
This commit creates a new data structure called 'sqfs_reader_t' that
takes care of all the repetetive tasks like opening the file, reading
the super block, creating the compressor, deserializing an fstree and
creating a data reader.
This in turn makes it possible to remove all the duplicate code from
rdsquashfs and sqfs2tar.

Improve file unpacking order2019-08-04T15:01:14+00:00David Oberhollenzerdavid.oberhollenzer@sigma-star.at2019-08-04T14:56:08+00:00urn:sha1:3a340b12eb9b7ed86a47391345cb836fa662b2d9
This commit moves the file unpacking order & job scheduling to a libfstree
function. The ordering is improved by making sure fragment blocks are not
extracted more than once and files with data blocks are extracted in order.
This way, serial unpacking of a 2GiB Debian live image could be reduced
from ~5' on my test machine to ~3.5', whereas parallel unpacking stays
roughly the same (~3' for -j 4).
