sstable cells are parsed into temporary_buffers, which causes large contiguous allocations for some cells. This is fixed by storing fragments of the cell value in a fragmented_temporary_buffer instead. To achieve this, this patch also adds new methods to the fragmented_temporary_buffer(size(), ostream& operator<<()) and adds methods to the underlying parser(primitive_consumer) for parsing byte strings into fragmented buffers. Fixes #7457 Fixes #6376 Closes #8182 * github.com:scylladb/scylla: primitive_consumer: keep fragments of parsed buffer in a small_vector sstables: add parsing of cell values into fragmented buffers sstables: add non-contiguous parsing of byte strings to the primitive_consumer utils: add ostream operator<<() for fragmented_temporary_buffer::view compound_type: extend serialize_value for all FragmentedView types
