2020-05-29cleanup: libsqfs: eliminate block writer statisticsDavid Oberhollenzer
- the "bytes submitted" can be moved over to the block processor - the number of blocks submitted are already there (implcitily, by adding the data block count to the fragment block count) - actual data bytes written can be computed from the super block - the remaining block count can be changed to simple counter that can be obtained through a function.

2020-02-12Implement a more explicit object systemDavid 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>
2020-02-12Clenaup: remove useage of sqfs_block_t from block writerDavid 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.

2020-02-10Cleanup: remove the fragment store/discard and block discard hooksDavid 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>

2020-01-31Split the block writing/deduplication away from the block processorDavid 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. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
