- Ported over BFS to the new cache API - Inode no longer inherits from CachedBlock, and therefore, no longer keeps the whole inode block in memory. It now has a copy of the bfs_inode structure in memory instead. This has a number of advantages but also some disadvantages, so it might be reverted later, even if it's unlikely. - Added a NodeGetter class that can be used whenever the real block needs to be accessed (ie. for attributes) - Changed *transaction to &transaction where possible - Removed support for KEEP_WRONG_DIRENT_RECLEN - Removed support for uncached file access since that's no longer needed - Fixed some endian issues in bfs_write_stat() - Removed the install BFS rules, since they don't make any sense anymore (unless you are running Haiku ;-)) Note, logged streams are not supported anymore right now. Also, the transaction code is pretty simple and slow - it will be improved later on. Attribute code is pretty much untested in the new environment. git-svn-id: file:///srv/svn/repos/haiku/trunk/current@10053 a95241bf-73f2-0310-859d-f6bbb57e9c96
