time: rearrange+pack vtm and time_object structs
struct time_object shrinks from 88 to 46 bytes on my 64-bit system.
* configure.in: use -Wno-packed-bitfield-compat for GCC 4.4+
use __attribute__((packed)) if available
* timev.h: shrink and pack struct vtm
* time.c: pack struct time_object and adjust/introduce helpers
