Version 2021.01.24: Feature redesign

- Removed RELAXED_RFC, will be supported as addtion in form of patches later - Remove Buffer_Info and use separate buffer types where it makes sense - Make FIFO a raw passthrough pipe - Redefine read/write _buffer - Rename buffer_offset_move to dequeue_bytes - Remove filtering, will be supported by separate binaries - Simplify registration and channel commits - Merge automatic replies in main.c - Remove path filtering, now only using fixed paths - Setup signals earlier - Add option for write_buffer to do a full flush or only partial if not possible - Use global buffers for registration
Refactor some code and more splitting

Alex D.	9a357c63e7	Version 2021.01.24: Feature redesign - Removed RELAXED_RFC, will be supported as addtion in form of patches later - Remove Buffer_Info and use separate buffer types where it makes sense - Make FIFO a raw passthrough pipe - Redefine read/write _buffer - Rename buffer_offset_move to dequeue_bytes - Remove filtering, will be supported by separate binaries - Simplify registration and channel commits - Merge automatic replies in main.c - Remove path filtering, now only using fixed paths - Setup signals earlier - Add option for write_buffer to do a full flush or only partial if not possible - Use global buffers for registration	2021-01-24 15:53:10 +00:00
