Rebase to bash-5.0
    
    - Remove 'bash-2.02-security.patch' patch as it does not seem to be
    needed.
    - Remove 'bash-2.05b-xcc.patch' as this change is already in upstream.
    - Remove 'bash-4.1-defer-sigchld-trap.patch' as this patch was doing
    nothing and this bug that it tried to solve should be fixed in upstream
    https://lists.gnu.org/archive/html/bug-bash/2012-03/msg00045.html
    - Remove 'bash-4.4-coverity.patch' as it has been upstreamed.
    - Delete several other patches that were not removed while rebasing to
    bash-4.4.
