The memory allocator should assert that the allocation succeeded.

[bcfriesen]

Currently we have

...
ptr = (type*) resist_malloc(size);
assert(ptr);
...

which leads to lots of asserts pasted all over the code base. We can make this more succinct by putting the assert in the allocator itself.

Actually, there already is an assert in the allocator (see line 32 of resist-memory.c). I will remove the redundant asserts in resist-context.c then.
