This is the first go at having the git index keep track of the
conversion mode and corresponding normalized blob for files.
The approach is relatively straight-forward:
* struct cache_entry has been extended with two fields,
norm_flags and norm_sha1, to keep track of the data.
* An accessor function ce_norm_sha1() has been added,
which checks that the fields seem valid, and otherwise
recalculates them.
* run_diff_files() and ce_compare_data() compare against
the normalized blob.
Still missing is a testsuite, and I may have missed some place
that ought to use ce_norm_sha1().
Thanks to Junio C Hamano for the suggestion.
Henrik Grubbström (Grubba) (5):
sha1_file: Added index_blob().
cache: Added ce_norm_sha1() and related cache_entry fields.
cache: Added index extension "NORM".
reachable: Made the gc aware of the ce_norm_sha1.
cache: Use ce_norm_sha1().
