2020-02-15	Cleanup: block processor: move init/cleanup functions into implemenations	David Oberhollenzer
	Again, the generic init/cleanup functions do way too many things that are specific to the thread pool implementation. Thanks to the splitting up of the block processor, they also have become quite trivial. This commit moves those functions into their respective implementations, allowing even further simplificiation.

2020-02-15	Cleanup: block processor: move finish function back into implementations	David Oberhollenzer
	The "generic" version actually uses specific internals of the thread pool implementation. Move it back into the thread pool based implementation and simplify the serial processor. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>

2020-02-15	Don't set error status on block processor for non-fatal errors	David Oberhollenzer
	If the API is mis-used or allocation fails, return an appropriate error code, but don't permanently break the block processor. It's easy to recover from that. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2020-02-15	Cleanup: block processor: remove delayed thread notification	David Oberhollenzer
	Under the assumption that block processing is CPU bound and not I/O bound, this is entirely useless. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2020-02-12	Implement a more explicit object system	David Oberhollenzer
	Make every dynamically allocated, opaque data structure inherit from a common sqfs_object_t structure with common entry points (e.g. destroy). This removes tons of public API functions and replaces them with a simple sqfs_destroy instead. If semantics of the (until now implicit) object system need to be extended, it can be much more conveniantely done this way. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2020-02-12	Cleanup: Move sqfs_block_t to block processor internals	David Oberhollenzer
	It was basically built around the block processor and exposed way too many internals. Removing it from other places was mostly trivial. This commit completely removes it from the public API and even most of the libsquashfs internals. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2020-02-12	Clenaup: remove useage of sqfs_block_t from block writer	David Oberhollenzer
	The sqfs_block_t structure has been written for the block processor and exposes way too many internals. This commit removes its usage from the block writer, cutting it down to the bare essentials, so the structure can be removed from the public API later on.

2020-02-10	Cleanup: remove block hooks entirely from block processor	David Oberhollenzer

2020-02-10	Cleanup: remove the fragment store/discard and block discard hooks	David Oberhollenzer
	There is no obvious non-footgun use for those other than tallying statistics, which is now done by the data structures themselves. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2020-02-10	Add run time statistics to the block writer and processor	David Oberhollenzer

2020-02-09	Move block writer and fragment table management out of block processor	David Oberhollenzer

2020-01-31	Split the block writing/deduplication away from the block processor	David Oberhollenzer
	This commit moves the entire block writing and deduplication of data blocks over to a different data type named "block writer". For simplicity, the interfaces of the block processor are left as is and are turned into warppers. Likewise, most of the code in the block writer is just verbatim from the block processor, to be cleaned up in subsequent commits.
