Allocation limit

[stepancheg]

Add an ability to limit the Bump size: if the number of allocated bytes exceeds the configured number, allocation should fail.

AFAIU, it is possible to make this feature with virtually no runtime overhead if the limit is checked only in alloc_layout_slow.

I would be open to reviewing and merging a PR that implements this functionality.

We should also have quickchecks that set random allocation limits, allocate from the bump and assert that the allocation limits are respected.

Hello! I tried my hand at implementing this feature, tell me what you think
