2019-09-20	Add sqfs_ prefix to data_reader_t & functions	David Oberhollenzer
	Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2019-09-20	Move data_reader_dump function out of data reader	David Oberhollenzer
	This commit adds two new functions for getting a file block by index, or a files fragment. The data_reader_dump function is rewritten in terms of those two functions and moved to a seperate file. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2019-09-20	Remove fstree code from rdsquashfs	David Oberhollenzer
	Use the directory reader from libsquashfs instead. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2019-09-20	Remove parallel unpacking	David Oberhollenzer
	Parallel unpacking didn't really improve the speed that much. Actually sorting the files for optimized unpack order improved speed much more than the parallel unpacker. Furthermore, the fork based parallel unpacker was actually pretty messy to begin with. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2019-08-04	Improve file unpacking order	David Oberhollenzer
	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).

2019-07-30	Add propper copyright headers to all source files	David Oberhollenzer

2019-07-25	Terminate the unpacker child processes if the main process exits	David Oberhollenzer
	Should the main process exit (e.g. the user presses CTRL+C) or explcitily sends it a signal, the desired behaviour is for the children to stop unpacking and exit. This commit adds a line to configure the kernel to send SIGKILL to the children if their parent dies. The same option also exists on various BSDs (not all of them) but with a different name which has to be checked for and adjusted should the program be required to run on one of those.
