[PATCH v3 0/5] Patches to avoid reporting conversion changes.

This is the third go at having the git index keep track of conversion mode changes for files.

Changes since last time:

  o The normalized sha1 is gone and replaced with a single bit
    (CONV_NORM_NEEDED).

  o The index extension "NORM" has been replaced with "CONV",
    since the only data to be saved is the conversion flags,
    and the format has been changed incompatibly.

  o The cache entry is now smudged on conversion mode change
    when relevant.

Henrik Grubbström (Grubba) (5):
  sha1_file: Added index_blob().
  strbuf: Added strbuf_add_uint32().
  cache: Keep track of conversion mode changes.
  cache: Added index extension "CONV".
  t/t0021: Test that conversion changes are detected.
