Caio Oliveira	89afcc94ea	util: Add a way to set the min_buffer_size in linear_alloc ... The default value remains 2048, which is also used for rounding up any user provided size. The option is useful in cases where there's a better idea of the amount of data that's going to be used.

Caio Oliveira	c005b5a16f	util: Avoid waste space when linear alloc'ing large sizes ... In the linear allocator, when a size larger than the minimum buffer size is allocated, we currently create the new buffer to fit exactly the requested size. In that case, don't bother updating the `latest` pointer, since this newly created buffer is already full. In the worst case, the current `latest` is full and it would be the same; in the best case, there's still room for small allocations, so we avoid wasting space if the next allocations would fit.

Caio Oliveira	1020cf8a82	util: Add a few basic tests for linear_alloc ... Not comprehensive, but those were the ones used to work on the previous linear_alloc changes. Also having a test already set up lower the barrier to add more tests for future in case of bugs.
