meltroutine_st, struct meltmixbigint_st, struct meltstring_st):
using GTY variable_size and @@MELTGTY@@ comment.

(melt_allocate_young_gc_zone, melt_free_young_gc_zone): New.
(delete_special, meltgc_make_special): Improved debug printf and
use melt_break_alptr_1...
(ggc_alloc_*) macros defined for backport to GCC 4.5
(melt_forwarded_copy): Don't clear the new destination zone in old
GGC heap.
(meltgc_add_out_raw_len): Use ggc_alloc_atomic.
