Since v1.7.9-rc1~10^2 (write_head_info(): handle "extra refs" locally,
2012-01-06), this trick to keep track of ".have" refs that are only
valid on the wire and not on the filesystem is not needed any more.
Simplify by removing support for the REFNAME_DOT_COMPONENT flag.
This means we'll be slightly stricter with invalid refs found in a
packed-refs file or during clone. read_loose_refs() already checks
for and skips refnames with .components so it is not affected.
