allocators: add freelist capability to Bucket; add provision for variable XOR fixed size allocs archive: re-tag file buffers if reading uncompressed from archive; improve LFH fixup logic file_cache: add cache line invalidation; lock down pages (readonly) when IO finished file_io: cleanup+docs; properly cut off at EOF without breaking alignment. file_stats: add seek accounting (WIP) vfs_optimizer: also record file_buf_free in the trace. initial implementation of archive builder (WIP) zip: lfh_fixup now more efficient (does not involve buffer manager - instead it grabs LFH from temp blocks) tex: plug FileIOBuf leak. avoid writing to tex.hm because that is a read-only file_buf. This was SVN commit r3428.
