fpclassify fix
EntityManager: rename getExtant -> GetExtantAsHandles, fix its
implementation+call site to avoid dynamic alloc/auto ptr, rename extant
-> IsExtant
vsnprintf2 -> sys_vsnprintf. remove printf.h (function is declared in
sysdep header)
use SUS/posix-ish strcasecmp instead of defining that to the
windows-only stricmp
add cppdoc for ia32/cpu
