[PATCH v5 0/8] Allocate cache entries from mem_pool

Changes from v4 are minor code review feedback items:

  - Remove extern keyword from new function definitions in cache.h
  - Make_cache_entry(..) functions work with object_id instead of sha
  - Add details to commit message for "block alloc: allocate cache entries from mem_pool"
  - Add details to commit message for "mem-pool: only search head block for available space"

The largest change is the new commit "read-cache: make_cache_entry should take object_id struct"
