- properly differentiate between buffer/offset alignment and length alignment (relevant since block size has been increased to 256k) - use VfsPath for most game paths instead of CStr - clean up timer interface and implementation - self-tests no longer crash - file_cache.cpp: fix for the case where allocation fails (prevent deleter from seeing a null pointer) - allocators: move all shared_ptr-related stuff to its own component; add DummySharedPtr - codec: disable checksums (important for performance at work) - File: made into an interface class to avoid export problems. not entirely sure about this.. - vfs_path.h, path.h, os_path.h: proper fix for using fs::change_extension and similar utility functions with derivatives of basic_path - lib_api: automatically link against import lib if building lib/ as a DLL - path_util: remove unused functions (this component is deprecated) - compiler.h: add INLINE - Xeromyces.cpp: pass PIVFS so that GetXMBPath works in self-test (should do this mostly everywhere rather than have one singleton g_VFS) This was SVN commit r5537.
