[PATCH 0/3] rename *.idx file into place last (also after *.bitmap)

["Ævar Arnfjörð Bjarmason" <avarab@gmail.com>]

I came up with this on top of Taylor's series which fixes the order in
which we write files associated with pack files[1]. His series fixes a
race where we write *.idx before *.rev, but left the issue of writing
*.bitmap after *.idx, this series fixes that. Now we'll really write
the *.idx last.

There's still a race in these combined serieses, but now it's to do
with our general lack of fsync(), i.e. there's no guarantee that just
because we write files A, B and C in that order that without doing the
proper fsync() dancing on the files and the fd for the directory that
other processes will see it that way. In practice though there is, as
few/no OS's are so pedantic as to expose inconsistent ordering of
written files in a directory, even though POSIX et al leave that
possibily open.

  pack-write: use more idiomatic strbuf usage for packname construction
  pack-write: split up finish_tmp_packfile() function
  pack-write: rename *.idx file into place last (really!)
