This is the result of single_worktree flag never being set (no way to up
until now). To get objects from current index only, set single_worktree.

The other add_index_objects_to_pending's caller is mark_reachable_objects()
(e.g. "git prune") which also mark objects from all indexes.

The core code is factored out and take 'struct index_state *' instead so
that we can reuse it to add objects from index files other than .git/index
in the next patch.

The "submodule" argument in this function is a path, which can have
either '/' or '\\' as a separator. Use is_dir_sep() to support both.

The revision walker can walk through per-worktree refs like HEAD or
SHA-1 references in the index. These currently are from the current
worktree only. This new flag is added to change rev-list behavior in
this regard:

When single_worktree is set, only current worktree is considered. When
it is not set (which is the default), all worktrees are considered.

The default is chosen so because the two big components that rev-list
works with are object database (entirely shared between worktrees) and
refs (mostly shared). It makes sense that default behavior goes per-repo
too instead of per-worktree.

The flag will eventually be exposed as a rev-list argument with
documents. For now it stays internal until the new behavior is fully
implemented.

Updates to the HTTP layer we made recently unconditionally used

When a directory is not readable, "gitweb" fails to build the
