[PATCH v3 0/3] Extract memory pool logic into reusable component

Changes from v2:

  - Code Review Reactions
  
  - Lifetime management functions for mem_pool will be included in
    future patch series

This patch series extracts the memory pool implementation, currently used by fast-import, into a generalized component. This memory pool can then be generally used by any component that needs a pool of memory.

This patch is in preparation for a change to speed up the loading of indexes with a large number of cache entries by reducing the number of malloc() calls. For a rough example of how this component will be used in this capacity, please see [1].
