* zip.h removed old test symbols
* path_util fixed bug in mixed-separating-slash handling
* renamed ERR_OK to INFO_OK; allows searching for "return ERR_" to yield
all actual errors (instead of having to filter out ERR_OK)
This was SVN commit r3945.
- file: make DirIterator opaque struct with type field, as with
File/FileIo in recent commit. unifies all dir enum interfaces.
- add dir open/nextent/close functions to FileProvider_VTbl
- allocators: change signature of SingleAllocator to that of the
templated type (avoids need for cast)
(affects archive, compression, zip)
- file_util: move dirent filter logic here so it can be used by file.cpp
also, not only vfs.
This was SVN commit r3822.
