Make amalgamtion the default when building. This way we can support fewer build configurations. Also, remove all undefined behavior due to use of memcpy with NULL pointers. GCC was exploiting this to remove NULL checks in some builds.

typedef struct JanetScratch JanetScratch;
Use make-image-dict and load-image-dict in thread/new Rather than messing with janet_core_dictionary, we instead cache the core enevironment, and pull out the needed tables from there. This is more flexible, more correct, and also exposes janet_resolve_core, which can be easily used from the C API.

Experimental changes to janet_call to make it faster. Remove setjmp and fiber creationg from janet_call. This adds the constraint to janet_call can only be called when there is already a current fiber.
