2019-08-23	Do bounds checking in metadata reader	David Oberhollenzer
	In all cases where metadata blocks are read, we can roughly (in some cases even preciesly) say in what range those metadata blocks will be, so it makes sense to throw an error if an attempt is made to wander outside this range. Furthermore, when reading from an uncompressed block, it is more reasonable to check against the actual block bounds than to padd it with 0 bytes.

2019-07-28	Fix free() of stack pointer in id_table_read error path	David Oberhollenzer
	We didn't allocate the ID table, so we don't need to free() it when reading from disk fails. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2019-07-25	Add generic read_table function similar to write_table	David Oberhollenzer

2019-07-25	Replace reads in squashfs with positional reads	David Oberhollenzer
	In most cases, we know exactely where the data that we want to read is on disk, so instead of using read() on the squashfs (or lseek + read), the code can in many places be cleaned up to use the pread wrapper read_data_at instead.

2019-07-24	Enable largefile support	Matt Turner
	Requires that config.h be included before other headers, since the macro _FILE_OFFSET_BITS changes the definitions of things like 'struct stat'. I chose to simply include it at the top of every C file and at immediately after the double-inclusion guards of every header.

2019-07-16	cleanup: move error handling into read_retry	David Oberhollenzer
	If read_retry fails to read the expected amount of data (EOF or otherwise), it is almost always an error. This commit renames read_retry to read_data and moves error handling into the function, making a lot of error handling code redundant.

2019-07-01	Make sure fragment and id tables are initialized	David Oberhollenzer
	In case the tables are not completely filled by reading from the squashfs image. Bug found using scan-build. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2019-06-10	Rename table.h to highlevel.h	David Oberhollenzer
	The idea is to move various higher level helper functions there. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
