janwas a859562ea7 improvements and fixes:
- 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.
