crt: Provide _aligned_* functions

Functions _aligned_free(), _aligned_malloc(), _aligned_offset_malloc(),
_aligned_offset_realloc() and _aligned_realloc() are available since
msvcr70.dll. For older CRT import libraries provide emulation via
mingw functions __mingw_aligned_free(), __mingw_aligned_malloc(),
__mingw_aligned_offset_malloc(), __mingw_aligned_offset_realloc() and
__mingw_aligned_realloc(). msvcrt.dll will use system implementation if
available, otherwise transparently fallback to mingw version.
