2021-03-22	Cleanup the block processor file structure	David Oberhollenzer
	A cleaner separation between common code, frontend code and backend code is made. The "is this byte blob zero" function is moved out to libutil (with test case and everything) with a more optimized implementation. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2021-03-21	Add a thread pool implementation to libutil	David Oberhollenzer
	The thread pool enforces ordering of items during dequeue similar to the already existing implementation in libsqfs. The idea is to eventually pull this functionality out of the block processor and turn it into a cleaner, separately tested module. The thread pool is implemented as an abstract interface, so we can have multiple implementations around, including the serial fallback implementation which we can then always test, irregardless of the compile config and run through static analysis as well.

2021-03-07	Optionally use a pool allocator for rb-tree nodes	David Oberhollenzer
	This commit restructures the rbtree code to optionally use a pool allocator for the nodes. The option is made depenend on the presence of a pre-processor flag. To the configure script is added an option to enable/disable the use of custom allocators. It makes sense to still allow the malloc/free based routes for better ASAN based instrumentation.

2021-03-07	Implement a custom memory pool allocator	David Oberhollenzer

2021-03-06	Add a generic implementation of a dynamic array to libutil	David Oberhollenzer
	The intention is to get rid of all the ad-hoc array implementations in the other components and cut down code size. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2020-05-19	Cleanup: move hash table header to include directory	David Oberhollenzer
	Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2020-04-27	Add hash table code to libutil.a	David Oberhollenzer
	Not only does this build the hashtable into libutil.a, it also makes sure the headers end up in the distribution tarball. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2020-03-18	Cleanup: Move xxhash32 code to libutil	David Oberhollenzer

2020-02-22	Add a very simple red-black tree implementation	David Oberhollenzer

2020-02-21	Cleanup: move utilities back out of libsquashfs	David Oberhollenzer
	This commit removes the allocation helpers and string table functions out of libsquashfs back into a "libutil.a". The problem of libsquashfs exporting stuff that it shouldn't is resolved by retaining the internal attributes and directly adding the source to libsquashfs instead of trying to somehow link against libutil.la.

2019-11-25	Cleanup: remove what is left of libutil	David Oberhollenzer

2019-11-25	Cleanup: move overflow safe alloc code into libsquashfs	David Oberhollenzer
	There were only a hand full of instances outside libsquashfs that used the alloc code. In most cases, the thing allocated hat its size derived from something already in memory anyway, so it is safe to assume its size fits into a size_t. At the same time, the opencoded Windows path conversion functions are all unified into a single helper function. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2019-11-24	Cleanup: completely move str_table into libsquashfs internals	David Oberhollenzer

2019-10-28	Add libutil implementation for strndup in case it isn't available	David Oberhollenzer
	"Some" "non-POSIX systems" don't have that. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2019-10-23	For Windows builds, remove the so-version, link libgcc statically	David Oberhollenzer
	The -static-libgcc flag has to be passed through the compiler with a "-Wc," prefix, because libtool tries to be clever about linker flags. If added directly to LDFLAGS, libtool removes it. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>

2019-10-07	Cleanup: move read_data function to libtar	David Oberhollenzer
	Its the only user. The other code doesn't touch raw file descriptors anymore. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2019-10-07	Cleanup: Move padd_file function to libtar	David Oberhollenzer
	It's only ever used for padding tarballs. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2019-09-27	Add a header for platform compatibillity fluff	David Oberhollenzer
	- We don't have "endian.h" everywhere. On some BSDs its in sys and on some BSDs the macros have different names. - We definitely don't have sysmacros.h on non-Unix-like systems. - Likewise for sys/types.h, sys/stat.h and their contents.
