[PATCH v4 0/3] branch: operations on orphan branches

Avoid some confusing errors operating with orphan branches when working with worktrees.

Changes from v3:

This is a major refactoring based on the comments from the reviews of v3. The intention is to make no functional changes in this iteration, except a change to maintain unchanged the user-visible behavior, as Jonathan suggested.

Summary of changes:

  - Inlined reject_rebase_or_bisect_branch() and
    replace_each_head_symref() into copy_or_rename_branch(). 

  - Used names to define HEAD states.

  - Moved die("Branch foo is being rebased/bisected...") after the call
    to validate_branchname(), to maintain the user-visible behavior.

  - Removed the use of ternary operators to avoid introducing unneeded
    noise in the patch.
