ERR_(FILE|PATH)_NOT_FOUND -> ERR_TNODE_NOT_FOUND, ERR_NOT_(FILE|DIR) -> ERR_TNODE_WRONG TYPE path_util: - path_append: bugfix (no more extraneous /); add support for appending slash - path_replace: bugfix (no more warnings for expected error) - add path_last_component, path_foreach_component - move some defs to the header that belong there from vfs.h/path.h file: add dir_create; move PosixFile definition here and provide accessor for fileio vfs: no longer automatically append slash; instead, make sure caller does vfs_mount: - mount_realpath: bugfix (strip trailing /), interface improvement - document write_target; clarify MULTIPLE_MOUNTINGS; add support for creating real dirs vfs_tree: - refactor TDir::add into find, add, find_and_add - fix TDir and TNode for dir-ends-with-slash requirement - split up lookup into lookup_cb and path_foreach_component - add support for inserting dirs with given mount point: tree_add_path (needed when mounting) wposix: get rid of weird PATH_MAX = 260 (Win32 weirdness) TextureManager: remove no longer needed SupportedTextureFormats GameSetup, Xeromyces: setup XMB location to data/cache/mods/official/xmb Util: HardcodedErrorString now uses error_description_r VFSUtil, i18n: fixes for dir slash issue Closes #79, #80 This was SVN commit r3874.
