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.

2019-07-16	cleanup: move error handling into write_retry	David Oberhollenzer
	If write_retry fails to write everything, it is always an error. This commit renames write_retry to write_data and moves error handling into the function, making a lot of error handling code redundant. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2019-07-04	Fix: possible out of bounds read in libcompress.a	David Oberhollenzer

2019-06-23	Move all handling of compressor names to libcompress.a	David Oberhollenzer
	This commit removes handling of compressor names from gensquashfs. Instead, functions are added to libcompress to obtain name from ID, ID from name and to print out defaults. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2019-06-11	Cleanup dependency handling	David Oberhollenzer
	Always try to gather all compressor libraries available, but only complain about missing a one if it has been explicitly selected. If a compressor has been explicityl disabled, we can still turn it off after checking. Also, rework gensquashfs to set the default compressor based on what's available.

2019-05-04	Rename lzma compressor to xz, zlib compressor to gzip	David Oberhollenzer
	Stick to the terminology that SquashFS uses. SquashFS uses "lzma" to refere to lzma1, "xz" to refere to lzma2 and confusingly "gzip" to refere to raw zlib deflate. We can avoid a lot of confusion by _consistently_ using the same terminology. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
