[PATCH 0/15] store length of commit->buffer

[Jeff King <peff@peff.net>]

Here's my series to drop "buffer" from "struct commit" in favor of a
slab, and then add in a length field. It's a lot of commits, but I tried
to break it down into readable chunks.

  [01/15]: alloc: include any-object allocations in alloc_report
  [02/15]: commit: push commit_index update into alloc_commit_node
  [03/15]: do not create "struct commit" with xcalloc
  [04/15]: logmsg_reencode: return const buffer
  [05/15]: sequencer: use logmsg_reencode in get_message
  [06/15]: provide a helper to free commit buffer
  [07/15]: provide a helper to set the commit buffer
  [08/15]: provide helpers to access the commit buffer
  [09/15]: use get_cached_commit_buffer where appropriate
  [10/15]: use get_commit_buffer to avoid duplicate code
  [11/15]: convert logmsg_reencode to get_commit_buffer
  [12/15]: use get_commit_buffer everywhere
  [13/15]: commit-slab: provide a static initializer
  [14/15]: commit: convert commit->buffer to a slab
  [15/15]: commit: record buffer length in cache
