  Branch: 8.0

Some more RAM + binary size optimizations.

o type_stack_mark is no longer inline, saves ~10Kb code size

o The type_stack and pike_type_mark_stack are now allocated on demand
when possible (using mmap, the pages are allocated when accessed at
least on macosx and linux)

This saves about 1Mb of RSS in a freshly started pike.
