adts: slight improvements allocators: change POOL_VARIABLE_ALLOCS to -1 for safety; fix invalid assumptions of it being 0 lib: more expressive param names file: add file_get_random_name for randomized trace generation; allow file_cache.h to declare externally visible file_buf_alloc API file_cache: zero-length file bugfix; also add several flags to the API routines allowing statistics gathering to be disabled (avoids distorting stats due to e.g. trace_entry_causes_io cache simulation) file_stats: add archive builder info; separate IO timing and seek accounting (-> correct results) trace: add random generation capability vfs: made responsible for cache hit/miss accounting (fixes cache miss rate display) This was SVN commit r3681.
