2022-11-22	Move gensquashfs specific code from libfstree to gensquashfs	David Oberhollenzer
	The "from dir" and from "from file" code, as well as the "sort file" code is specific to gensquashfs, so move them there and the test cases as well. The medium term idea is to reduce libfstree to a stub, merge it into the generic writer and ultimately hoist that into libsquashfs.

2022-03-30	Add sort-file implementation	David Oberhollenzer
	A `flags` field and `priority` are added to all file information structs. A news fstree function is introduced for parsing a "sort-file". Each line in the file is space separated, and has the following format: priority [flags] filename Priority is a 64 bit number, flags are optional and filename can be put in quotes if it is supposed to start or end with spaces. Single line comments can be used. The flags can be used to set block-processor flags (e.g. don't fragment, or don't compress), as well as instructing the parser to use file globbing to match the filename. After parsing the file, the list of file info structure is sorted according to the priority (default is 0) using a stable sort algorithm.

2019-12-22	Add basic support for handling and serializing hard links	David Oberhollenzer
	In libfstree, add a function to add a hard link to the fstree. The hard links stores the target in the data.target field, canonicalizes the target and sets a sentinel mode. A second function is used to resolve link, i.e. replacing it with a direct pointer, setting another sentinel mode and increasing the targets link count. The post process function tries to resolve unresolved hard links and only allocates inode numbers for nodes that aren't hard links. If the target node of a hard link does not have an inode number yet, the two need to be swapped, since this is also the order in which they are serialized. The serialization function in libcommon simply has to skip hard link nodes and when writing directory entries, use the inode num/ref of the target node.

2019-12-18	Cleanup: merge the fstree post processing functions	David Oberhollenzer
	Instead of having 3 different functions for sorting the tree, numbering the nodes and generating a file list, that all have to be used in the right order, this commit merges them into a single "fstree_post_process" function. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>

2019-09-28	Move fstree selinux code to gensquashfs	David Oberhollenzer
