2023-01-19Implement rudimentary reference counting for sqfs_object_tDavid Oberhollenzer
Implement grab/drop functions to increase/decrease reference count and destroy the object if the count drops to 0. Make sure that all objects that maintain internal references actually grab that reference, duplicate it in the copy function, drop it in the destroy handler.

2022-07-08Cleanup: move libutil headers to sub directoryDavid Oberhollenzer
Move all the libutil stuff from the toplevel include/ to a util/ sub directory and fix up the includes that make use of them. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2020-07-29Fix: xattr reader: read the header after seaking to an OOL valueDavid Oberhollenzer
If an xattr value is stored OOL, the value actually holds an 8 byte reference to another, previously stored value. This reference points to the header that we need to read to know the actual size of the value before reading it, not the value itself, so after reading the reference and seeking to it, the xattr reader needs to read the actual header.
