Improve binary garbage collection
The garbage collector in r13b03 is too aggressive in some cases. This commit raises the level of default initial allowed binary garbage (virtual heap for binaries) before collecting from 233 words to 46368 words (181 kB on 32-bit). A new option, min_bin_vheap_size, has been added to spawn_opt, system_flag and process_flag can be used to change the default values. The option can also be used with system_info and process_info to inspect the values. For symmetry the option min_heap_size has been added to the above functions where it was previously missing. Add testcases for min_bin_vheap_size and min_heap_size for functions process_flag/2, process_info/2, system_info/2 and spawn_opt/2.
